#

Let's see how many times until it doesn't work?

#

Second time goes well

old mango Aug 16, 2022, 4:15 AM

#

Yep

wary cloak Aug 16, 2022, 4:16 AM

#

Third time also

old mango Aug 16, 2022, 4:16 AM

#

Repetition is good for finding heisenbugs like these

wary cloak Aug 16, 2022, 4:16 AM

#

Fourth also mmm

#

Let's try

#

Combining functions

#

Now I will do charging money

#

Doesn't work

#

I will reset

#

Let's try it again

#

Charging money

#

It works

#

Let's go read saldo

#

It works

#

Let's try charging money again

#

Mmm

#

It worked

#

Then read saldo again

#

It worked

#

Well now it's all working huh, yeah but when I'm testing it doesn't

#

Mm

#

Let's try to buy then

#

ferrisHmm

#

It worked wtf

#

And reading

#

That's weird

#

But I told you those other two cases when it stopped working

#

That's why I call it inconsistency

#

It went from failing a lot from being perfect now

#

Ok now let's try master mode then

#

Works

#

Read saldo

#

It doesn't

#

Finally

#

Ok let's reset

#

Now I will try

#

Read saldo

#

Do master mode

#

And try read saldo again

#

ferrisHmm

#

It works

#

Any conclusion yet(?

#

I'm really lost there's no pattern

#

Aha

#

No I went charge money it didn't work

#

And there were only 4 operations this time

#

Ok let's try repeat that behavior

#

Read saldo
Master mode
Read saldo
Charge money

#

It worked

#

ferrisPensive

#

Any more test?

old mango Aug 16, 2022, 4:26 AM

#

So, is it still being inconsistent?

wary cloak Aug 16, 2022, 4:26 AM

#

Yes as you read

#

Because I did that for operation thing and it didn't work but then repeat it and it did

#

4 operation*

old mango Aug 16, 2022, 4:27 AM

#

I think it's something to do with the halt state

#

If you repeat the operations quickly does it it have issues more often than when you pause in between?

wary cloak Aug 16, 2022, 4:28 AM

#

I don't think so but we could try

#

For example ver saldo

#

Has like a

#

10 second delay

old mango Aug 16, 2022, 4:28 AM

#

Pause as in move the card away from the reader for a while

wary cloak Aug 16, 2022, 4:28 AM

#

Buy well the time I take you write the number

#

and so on

wary cloak Aug 16, 2022, 4:29 AM

#

old mango Pause as in move the card away from the reader for a while

I didn't understand

old mango Aug 16, 2022, 4:30 AM

#

Actually, hmm. Try commenting out all the HaltA calls and see if you still have issues?

wary cloak Aug 16, 2022, 4:30 AM

#

All?

#

Isn't it necessary to do that with stop crypto?

old mango Aug 16, 2022, 4:30 AM

#

I'm not 100% clear on that

wary cloak Aug 16, 2022, 4:31 AM

#

Ok let's try

old mango Aug 16, 2022, 4:31 AM

#

And ISO 14443 (the relevant specification) costs money to buy

wary cloak Aug 16, 2022, 4:31 AM

#

Tho as you see it takes time to get the inconsistency

#

Or not

#

Because it's inconsistent(?

old mango Aug 16, 2022, 4:33 AM

#

PICC_IsNewCardPresent documentation says that 'Sleeping cards in state HALT are ignored'

wary cloak Aug 16, 2022, 4:33 AM

#

I saw something interesting

#

#

Here there's not a haltA

#

There's in the if not in the else

old mango Aug 16, 2022, 4:34 AM

#

There also not StopCrypto

wary cloak Aug 16, 2022, 4:34 AM

#

Maybe it's fine but saying

#

Btw I think I comented all

old mango Aug 16, 2022, 4:35 AM

#

Well, give it a shot, ig?

#

Hopefully doesn't cause any issues

wary cloak Aug 16, 2022, 4:35 AM

#

But in any case if that was the issue it would always fail when getting there but then there's this other try when I did the 4 operation going through master mode again and nothing happened so

#

Went to

#

Leer saldo

#

Did it two times, third it got stuck

#

Let's repeat the behavior

#

And see if it gets stuck again

#

It doesn't work now

#

In first try

#

Reset again

#

Now it works

#

Tch

#

Just when I thought we found a common behavior

#

And if I do it a second time it works too

#

Third time also

#

Any other idea or keep testing?

old mango Aug 16, 2022, 4:38 AM

#

Well, I'd uncomment those lines you changed

#

Add any missing haltA or stopCrypto

wary cloak Aug 16, 2022, 4:39 AM

#

I hope I didn't go too back

#

Cause I saw int precio again

#

Got rid of it ofc

old mango Aug 16, 2022, 4:39 AM

#

If it still doesnt work, maybe try PICC_REQA_or_WUPA?

wary cloak Aug 16, 2022, 4:40 AM

#

old mango Add any missing haltA or stopCrypto

Hard to know where I think I will add them in that else but I think there's no other place

wary cloak Aug 16, 2022, 4:40 AM

#

old mango If it still doesnt work, maybe try PICC_REQA_or_WUPA?

What's that?

old mango Aug 16, 2022, 4:41 AM

#

Can do a ctrl-F in the MFRC522.cpp

#

I think it's documented there

#

Or, hmm, actually

wary cloak Aug 16, 2022, 4:42 AM

#

Well it's getting really late so I think we better at least for now don't continue on with this because it can end up being a lot of wasted time maybe that's another thing we should leave alone and deal with it because It just doesn't make sense either

old mango Aug 16, 2022, 4:42 AM

#

PICC_IsNewCardPresent is what i think is the culprit

wary cloak Aug 16, 2022, 4:42 AM

#

I mean it could be

old mango Aug 16, 2022, 4:42 AM

#

Because it only works on cards in the IDLE state

wary cloak Aug 16, 2022, 4:42 AM

#

Remember that

old mango Aug 16, 2022, 4:43 AM

#

And doesnt do anything to cards in HALT

wary cloak Aug 16, 2022, 4:43 AM

#

Where I first discovered and were more often

#

We're with new card present in master mode

#

Remember when I told you when printing it I got

#

11111110000011111100000111000010011

#

And once I had to

#

Read the card 7 times

#

Wait so maybe

#

When doing this process

#

I get to the haltA state

#

So when I ask for a new card present I get ignored?

old mango Aug 16, 2022, 4:44 AM

#

Yeah

wary cloak Aug 16, 2022, 4:45 AM

#

Tho I mean even then

old mango Aug 16, 2022, 4:45 AM

#

I think the card eventually goes back into IDLE

#

Im just not sure how that process works

wary cloak Aug 16, 2022, 4:45 AM

#

That wouldn't explain the inconsistency because I always go through haltA and go to a new card present again

#

Ig

#

Mmm

#

So maybe it's merely a hardware very specific issue?

old mango Aug 16, 2022, 4:47 AM

#

Cuz it's an RFID card, it doesn't have onboard power, so it's probably going to reset itself within a certain amount of time

wary cloak Aug 16, 2022, 4:47 AM

#

So may he it's time

#

Well I think we can't do anything else about it

#

So there's this last thing of the personalized characters and

#

It would be done

#

Bye bye rfid

old mango Aug 16, 2022, 4:48 AM

#

Do you have your reader's data sheet?

wary cloak Aug 16, 2022, 4:48 AM

#

I will try this one

#

Well above they sort it out(?

#

Somehow

#

.

#

.

#

.

#

.

#

Like that

#

Tho they found it in the document or smth

#

Just when you came

#

Anyways I'm trying this

#

lcd.createChar(0x01, {
0x0d, //0,0,0,0,1,1,0,1
0x12, //0,0,0,1,0,0,1,0
0x00, //0,0,0,0,0,0,0,0
0x16, //0,0,0,1,0,1,1,0

0x11, //0,0,0,1,0,0,0,1
0x11, //0,0,0,1,0,0,0,1
0x11, //0,0,0,1,0,0,0,1
});

#

Replacing every place when an ñ should be with \x01

#

Tho then even if it worked I still need the ¿

Try doing createChar before you init

#

Ok

wary cloak Aug 16, 2022, 5:04 AM

#

wary cloak contrase\x01a

Is this ok?

Oh actually nvm dont

old mango Aug 16, 2022, 5:04 AM

#

old mango Try doing createChar before you init

*dont do this one

wary cloak Aug 16, 2022, 5:05 AM

Well I already tried that and it failed (?

Here is that

Huh

#

Weird

hallow hinge Aug 16, 2022, 5:09 AM

#

I edited it but forgot to message lol

old mango Aug 16, 2022, 5:09 AM

#

Looking at it, you might have to use lcd.printByte or lcd.write (not sure what it's called) to write custom characters

wary cloak Aug 16, 2022, 5:09 AM

#

hallow hinge I edited it but forgot to message lol

Oh I was thinking how the hell I missed it(?

old mango Aug 16, 2022, 5:10 AM

#

Or maybe print()?

wary cloak Aug 16, 2022, 5:10 AM

#

Mmm

old mango Aug 16, 2022, 5:10 AM

#

LiquidCrystal_I2C is abandoned so it's hard to see what exactly the correct way is

wary cloak Aug 16, 2022, 5:10 AM

#

It would look so bad tho combining my function with a normal one

#

can't we maybe change my function?

#

To accept that?

old mango Aug 16, 2022, 5:11 AM

#

Idk, maybe?

wary cloak Aug 16, 2022, 5:11 AM

#

old mango Or maybe print()?

It's lcd.print

old mango Aug 16, 2022, 5:11 AM

#

I think you might need lcd.write for custom chars

wary cloak Aug 16, 2022, 5:11 AM

#

Could be

#

Could try in setup maybe

#

void setup() {

  lcd.clear();
  lcd.write("\x01");
  lcd.clear();

  delay(5000);
}

old mango Aug 16, 2022, 5:13 AM

#

Oh, no

wary cloak Aug 16, 2022, 5:13 AM

#

?

old mango Aug 16, 2022, 5:14 AM

#

lcd.write(1) not write("\x01")

wary cloak Aug 16, 2022, 5:14 AM

#

Ok it didn't work it didn't show anything

wary cloak Aug 16, 2022, 5:14 AM

#

old mango lcd.write(1) not write("\x01")

K let's see

#

I'm trying it with my function tho

#

Rn

#

Nah there it doesn't work

old mango Aug 16, 2022, 5:15 AM

#

If that doesnt work, switch from createChar(1, ...) to createChar)(0, ...) and then try with lcd.write(0)

wary cloak Aug 16, 2022, 5:15 AM

#

wary cloak ```rust void setup() { pinMode(PIN_ACOMPANANTE3, OUTPUT); pinMode(PIN_ACOMPA...

Ok let's see with this setup

#

Tho I realized

#

The delay is wrong bruh

#

Well

#

lcd.clear();
  lcd.print("\x01");
  delay(5000);
  lcd.clear();
  lcd.write("\x01");
  delay(5000);
  lcd.clear();

old mango Aug 16, 2022, 5:18 AM

#

Wait that's the wrong lcd.write tho

wary cloak Aug 16, 2022, 5:18 AM

#

That worked

#

Tho it first printed the ñ then a 0 for some reason

#

I will see what happens I only do print

#

Not write

#

It works

#

Weird but

#

If it works with print

#

Why doesn't it with my function?

#

I have one theory tho

#

"\x01" Does this really count like one character?

old mango Aug 16, 2022, 5:21 AM

#

Yes, it does

wary cloak Aug 16, 2022, 5:21 AM

#

Because I have 20 character limit and the contraseña it's not short word

#

Is that I thought

old mango Aug 16, 2022, 5:21 AM

#

That's something that C++ itself handles

wary cloak Aug 16, 2022, 5:21 AM

#

Since it's says "contrase"

#

Not even

#

Contrasea

#

I thought maybe it run out of space

#

Why does the A disappear

#

BTW

wary cloak Aug 16, 2022, 5:22 AM

#

wary cloak ```rust lcd.clear(); lcd.print("\x01"); delay(5000); lcd.clear(); lcd.wr...

This doesn't work with write

#

It prints a 0 with a line at the middle or smth like that

#

It works with print but

#

Then

old mango Aug 16, 2022, 5:23 AM

#

With write(1) or write("\x01")?

wary cloak Aug 16, 2022, 5:23 AM

#

Why not with my function that uses print

wary cloak Aug 16, 2022, 5:23 AM

#

old mango With write(1) or write("\x01")?

Both I tried both

#

Now I will try print with 1

#

It doesn't

#

lcd.print("\x01");

#

this is the way

#

But again

wary cloak Aug 16, 2022, 5:24 AM

#

wary cloak Why not with my function that uses print

.

old mango Aug 16, 2022, 5:25 AM

Okay gimme a sec, i have an i2c lcd and an arduino lying around here somewhere

wary cloak Aug 16, 2022, 5:25 AM

#

Sure and I will leave my function here I sent it to a friend once so

#

I have it by itself

old mango Aug 16, 2022, 5:26 AM

#

I already have it, no need

wary cloak Aug 16, 2022, 5:26 AM

#

Oh ok

#

I was going to try this

#

imprimir(
    { "\x01",  'c' },
    );
  delay(5000);
  lcd.clear();

#

And it works

#

So

#

My function can print the ñ

#

Now

wary cloak Aug 16, 2022, 5:32 AM

#

wary cloak contrase\x01a

Why not here

#

For example

#

imprimir(
    { "\x01a",  'c' }
    );
  delay(5000);
  lcd.clear();

}

#

This prints nothing

#

Like in that other case

#

imprimir(
    { "\x01 a",  'c' }
    );

#

It works but

#

There's and space between the two

#

There should be a way to print them together

#

@coral geyser happen to now?

#

Know*

#

And if case still around @hallow hinge any clue?

hallow hinge Aug 16, 2022, 5:36 AM

#

"\x01" "a" should work without space

old mango Aug 16, 2022, 5:36 AM

#

Aight, found my stuff, writing

wary cloak Aug 16, 2022, 5:36 AM

#

Nice

wary cloak Aug 16, 2022, 5:36 AM

#

hallow hinge `"\x01" "a"` should work without space

Let's try it

#

Ok it works

#

Noe let's try it in a real scenario

#

Now*

#

Lot's of errors

#

No wait

#

Ok solve that

#

Let's see

#

It wooooorks

#

Now I will implement it everywhere and see if it's done

#

@hallow hinge thank you for the ñ

#

Think you could the ¿ and we call it a day?

#

Tho I still have to check the ñ works everywhere but it likely does

#

It works everywhere yay

#

@old mango the ñ affair has been solved

#

Tho there's only one issue

#

#

imprimir(
    { "contrase""\x01""a" "correcta.",  'c' },
    { "Acerque la tarjeta", 'c' },
    { "al lector", 'c' }
    );

#

No clue why there's no space there

#

I tried doing and extra space also

#

Any idea?

#

:D

#

I created ¿

#

By my own

#

uint8_t QUESTION[8] = {
    0x00, //0,0,0,0,0,0,0,0
    0x04, //0,0,0,0,0,1,0,0
    0x00, //0,0,0,0,0,0,0,0
    0x04, //0,0,0,0,0,1,0,0
    0x08, //0,0,0,0,1,0,0,0
    0x10, //0,0,0,1,0,0,0,0
    0x11, //0,0,0,1,0,0,0,1
    0x0e, //0,0,0,0,1,1,1,0
    };

#

So Happy

#

Now let's see if I can use it

#

It woooorks

wary cloak Aug 16, 2022, 6:05 AM

#

wary cloak

So now we only have the solve this

wary cloak Aug 16, 2022, 6:05 AM

#

wary cloak ```rust imprimir( { "contrase""\x01""a" "correcta.", 'c' }, { "Acerque ...

.

#

And that's it

#

There's nothing else

#

@old mango I hope you aren't doing a whole setup for the lcd(?

#

@oblique bridge could you help me solve this last issue?

#

Well ig this will have to he left for a 2 minute section tomorrow

old mango Aug 16, 2022, 6:10 AM

#

wary cloak <@328740666651705356> I hope you aren't doing a whole setup for the lcd(?

Welp ,_,

#

Looks like you got it working tho

wary cloak Aug 16, 2022, 6:11 AM

#

I just experienced another inconsistency trying to read money for the first time

#

Since it's the first time I don't think time played a role here

#

But again

#

I don't know if we can do anything about it

wary cloak Aug 16, 2022, 6:11 AM

#

old mango Looks like you got it working tho

Just an issue

wary cloak Aug 16, 2022, 6:11 AM

#

wary cloak

I can't get a space there for any reason

wary cloak Aug 16, 2022, 6:12 AM

#

wary cloak ```rust imprimir( { "contrase""\x01""a" "correcta.", 'c' }, { "Acerque ...

.

old mango Aug 16, 2022, 6:12 AM

#

You have "contraseña""correcta" there are no spaces in that to begin with?

wary cloak Aug 16, 2022, 6:12 AM

#

There are

old mango Aug 16, 2022, 6:13 AM

#

Not in that string you're passing it

wary cloak Aug 16, 2022, 6:13 AM

#

"contrase""\x01"" a" "correcta"

#

And even if I did

#

Another space

#

It doesn't change

old mango Aug 16, 2022, 6:13 AM

#

There's a space before the a but none between a and correcta

wary cloak Aug 16, 2022, 6:14 AM

#

Oooh

#

Let's see

#

Done

#

Bye bye cpp rfid I hope at least you made me a better programmer

#

Ofc we have two little details

#

That of "the card is already in the system" Affair we couldn't solve and the inconsistentencies

#

So it's not 100% perfect but at least like 90

old mango Aug 16, 2022, 6:17 AM

#

wary cloak <@328740666651705356> I hope you aren't doing a whole setup for the lcd(?

At least i didnt waste too much time on it 😔

wary cloak Aug 16, 2022, 6:18 AM

#

Sorry for that

old mango Aug 16, 2022, 6:18 AM

#

Nah np

#

Most of it was just finding stuff

wary cloak Aug 16, 2022, 6:19 AM

#

Now finally before I went to sleep I wanted to tell you what's next tho maybe we aren't working on it for a week of something I ain't sure about that because I don't have the components yet and I have a small issue when I do

old mango Aug 16, 2022, 6:19 AM

#

And like i said i have a project I'm starting soon anyway so not like it was out of my way or anything

wary cloak Aug 16, 2022, 6:19 AM

#

So next two components and last

#

4 Ultrasound sensors and 1 infrared?

#

Idk how you call it in English

old mango Aug 16, 2022, 6:20 AM

#

About the same

wary cloak Aug 16, 2022, 6:20 AM

#

Basically if there's a glass you can serve the drink on keep on buddy, if not, it won't work

old mango Aug 16, 2022, 6:21 AM

#

Ultrasonic & infrared, prolly

#

Ultrasound is more the medical thing, in common speech at least

wary cloak Aug 16, 2022, 6:21 AM

#

And the ultrasonic would be on the top of the recipient so it would warn you hey you have 3 uses left, and then it would say, fill me or I won't work

#

Basically that

#

Pretty easy right?

#

I already have an ultrasonic code that use as a base, it's pretty simple and there are no libraries involved

#

#define trig 10
#define echo 9
float tiempo;
float dist;

void setup() {
pinMode (trig, OUTPUT);
pinMode (echo, INPUT);
Serial.begin(9600);
}



void loop() {

digitalWrite(trig, HIGH);
delayMicroseconds(10);
digitalWrite(trig, LOW);
tiempo= pulseIn(echo, HIGH);
dist=tiempo*0.01715;
if(dist<=300)
{Serial.print("Distancia en cm: ");
Serial.println(dist);
delay(500);}
else
{Serial.println("Muy lejos");
delay(500);}

}

#

Now ofc

#

First this Wednesday I should show all the rfid stuff but aside from that we are testing the base functionality irl last time it didn't work

#

So they maybe tell me don't get onto new stuff if old one doesn't work at all

#

Or even then my partner takes it's time to buy the sensors

old mango Aug 16, 2022, 6:23 AM

#

Didnt really understand what you were saying but those are fairly simple sensors so there shouldn't be any issues for you

wary cloak Aug 16, 2022, 6:23 AM

#

All sort of stuff could happen

wary cloak Aug 16, 2022, 6:24 AM

#

old mango Didnt really understand what you were saying but those are fairly simple sensors...

I think I will try to do it alone but in any case I may need a small hand

#

I have only one issue

#

Ofc since I have a MEGA likely I have enough pins left for the sensors

#

But you know what I don't have more of?

#

VCC and GND

#

So yeah though trying them

#

At least all the components together

#

It's going to be a pain

#

And also testing ultrasonic would requiere it to be where it needs to because you know it won't work as intended if not and also

#

It's really imprecise

old mango Aug 16, 2022, 6:26 AM

#

Oh, yeah, ultrasonic is indeed somewhat imprecise

wary cloak Aug 16, 2022, 6:26 AM

#

But yeah that and

#

The project is done

#

Maybe I could make it better but

#

Not with more components and libraries

#

But with what I already have

#

For example for now it works only in one case one drink, I could change that

#

And honestly I would be up to make more personalized characters

#

Like a bottle or something cool

old mango Aug 16, 2022, 6:28 AM

#

Can prolly expect a few percent off, more if it's not a flat surface or the sensors are low quality

wary cloak Aug 16, 2022, 6:29 AM

#

I will measure the distance and pick the lowest and highest

#

That was my idea

old mango Aug 16, 2022, 6:29 AM

#

Also they usually have a minimum range that you need to keep in mind

#

Oh, and it'll also be affected by temperature and humidity to a certain extent

wary cloak Aug 16, 2022, 6:30 AM

#

Really?

old mango Aug 16, 2022, 6:30 AM

#

Air pressure, too, iirc

wary cloak Aug 16, 2022, 6:31 AM

#

Well in any case we already tested it on water

old mango Aug 16, 2022, 6:31 AM

#

Yeah, used an ultrasonic sensor for measuring change in speed of sound with temperature/pressure/humidity

wary cloak Aug 16, 2022, 6:32 AM

#

Well so as you see no clue when are we continuing this ofc we could program without the components so when we have there's less work but idk

#

So I guess I may continue the rust re writting, bye bye cpp rfid hello rust rfid

#

Well gn, and thank you very much a nightmare has finished (?

arctic mist Aug 16, 2022, 7:30 AM

#

guys what the fuck

#

that is impressive

wary cloak Aug 16, 2022, 7:19 PM

#

The usual when I'm speaking (?

#

arctic mist guys what the fuck

Did we pass the record yet?

#

This thread has been at the top of #981431291683700776 for what 2 weeks now?

wary cloak Aug 16, 2022, 10:25 PM

#

@coral geyser question

#

So tomorrow I'm having that class again

#

About the USB

#

The only thing I should different is when finishing the setup I should run all comands with "--offline"? Like "cargo check --offline"?

coral geyser Aug 16, 2022, 10:32 PM

#

Yeah that's all I can think of

#

Other than remaking it with a different filesystem so rustup and cargo behave normally

wary cloak Aug 16, 2022, 10:38 PM

#

coral geyser Other than remaking it with a different filesystem so rustup and cargo behave no...

Remaking it with a different file system?

#

Btw I would like to retake the rust re writting and so since the cpp one is really advanced now

#

Tho not today

#

Like in two days

#

Could you help me again?

coral geyser Aug 16, 2022, 10:41 PM

#

wary cloak Could you help me again?

Sure

coral geyser Aug 16, 2022, 10:42 PM

#

wary cloak Remaking it with a different file system?

Currently it has Fat32 but that doesn't support shortcuts and locking files. If we changed it to ntfs (the default for a windows drive) then it should behave normally

wary cloak Aug 16, 2022, 10:44 PM

#

Mmm well in that case

#

If it doesn't work the offline

#

I will use my own pass all the stugf again

#

And it that one

#

We can do what you just said

coral geyser Aug 16, 2022, 10:46 PM

#

All the weird errors you have seen with it on the other computers is because cargo tries to do something that fat32 doesn't support and it gets really confused. I am hoping using --offline will make it not try to do those things

wary cloak Aug 16, 2022, 11:59 PM

#

Oh

#

Tho..

#

What's fat32?

coral geyser Aug 17, 2022, 12:28 AM

?

wary cloak Aug 20, 2022, 3:07 AM

#

old mango ?

Haven't tested it yet but

#

I let one classmate play with the project

#

In one moment he changed the password to idk what so I said

#

Good moment to show off I have a master mode for this cases

#

But it didn't work

#

If I remember correctly before finishing to write it, it would already say incorrect password

#

My first thought is maybe because it was shorter so it didn't give me enough time to complete it

#

Ah. .

#

I know what it can be

#

So.

#

I don't remember the code like that much but

#

I think we had in a variable the length of the password entered by the user the first time

#

And we use it in the for loop for getting the user password

#

So if the password is shorter than the master password I won't get to write it

#

I guess when I tried at home they always had the same length

#

There's a lot of possible solutions, not giving freedom to the user and having the password be a fixed size (easy way out I would like to avoid it) or find a way so that master password matches regardless

#

What I'm not sure is if the problem only arises when the password is shorter

#

If is equal length it won't

#

But would it if it's longer?

#

I think maybe when we get an user password we don't set how much he can write based on the current password len

#

But rather

#

Just like create password function say, well you can type whatever but I will stop you at character 10 or you can finish earlier with "#"

#

If the code is as I remember that may fix it

wary cloak Aug 20, 2022, 5:53 PM

#

@coral geyser btw I tried the offline solution

#

And got this

#

C:/Users/Taller03/Desktop/simple_bartender # cargo check --offline
error: failed to download `paste v1.0.8`

C:/Users/Taller03/Desktop/simple_bartender #

#

So yeah

#

We will have to do it the other way

#

I actually wanted to try doing it today

#

Well my road map for today would be:
1- Do the django web I have to hand in (tho if my tutor doesn't answer my question about what I have to do, I can just do the base)

2- fix the master password issue of the Arduino project

3- solve the pendrive issue ideally

4-and finally if it's a great day we could start the rfid part of the rust re writing project

#

And I have a question about the last one, Do I do git repository for it? Now that I more or less know

wary cloak Aug 22, 2022, 1:47 AM

#

@old mango i tried Solving the issue on my own but I couldn't

old mango Aug 22, 2022, 1:48 AM

#

Which issue?

wary cloak Aug 22, 2022, 2:03 AM

#

old mango Which issue?

This one

wary cloak Aug 22, 2022, 2:03 AM

#

wary cloak Haven't tested it yet but

.

#

Tho now

#

I can properly tell you

#

Because I tested it

#

And it was as a I thought

#

Master password works only ik the scenario

#

Where your password and the master password has the same length

#

If less it won't let you write it all and it will say beforehand is incorrect

#

If longer it won't stop when you type it and it will go on

#

I thought the solution was fairly easy

#

Mimic how you get a password in create password, until 10 characters or stop with #

#

Because rn

old mango Aug 22, 2022, 2:05 AM

#

Mmhm

wary cloak Aug 22, 2022, 2:05 AM

#

The for loop is until you reach password len

#

You see currently waitForPassword is like this

#

char* waitForPassword(char* user_password){
  int i;
  int password_len = EEPROM.read(254);
  for(i=0;i<password_len;i++){
    char input = keypad.waitForKey();
    user_password[i] = input;
  }
  user_password[i] = '\0';
  return user_password;
}

#

And I tried changing it to this instead

#

char* waitForPassword(char* user_password){
  int i;
  int password_len = EEPROM.read(254);
  for(i = 0; i < 10; i++){
     char input = keypad.waitForKey();
     if(input != '#'){
       user_password[i] = input;;
     } else {
       break;
     }
  user_password[i] = '\0';
  return user_password;
  }
}

#

Forgot to get rid of password len declaration

#

But ignore it

#

Strangely

#

This didn't work

#

If I remember correctly now I can like type only one character for any reason so ofc it will say is incorrect

#

What I did do was change the text of "write your current password" To give now the feedback of how it works now

#

Tho it was a bit hard because of character limitation but I guess this is enough

#

imprimir(
      { "Ingrese",  'c' },
      { "su contrase""\x01""a", 'c' },
      { "actual y finalice", 'c' },
      { "con #", 'c' }
         );

#

Anyways

#

That's the issue idk why my solution didn't work and more so why it failed like it did

old mango Aug 22, 2022, 2:09 AM

#

Is waitForPassword giving the correct value?

wary cloak Aug 22, 2022, 2:10 AM

#

Wdym?

#

I mean it should I only changed the for loop nothing else it returns the same thing and has the same structure

#

Only changes is that now the for loop goes until 10 or it breaks when #

#

Nothing else ao

#

So*

old mango Aug 22, 2022, 2:11 AM

#

Where in the code is the failure occurring? It looks like waitforpassword is fine and I'm a bit confused by what the current issue is

wary cloak Aug 22, 2022, 2:12 AM

#

Actually now that you say it

#

I didn't try in the other place where I used wait for password

#

But aside from that

#

It is wait for password

#

I go to change password

#

It ask me for my password

#

I type like one character

#

It says incorrect password

#

It doesn't let me write anything now

#

And ofc is because for any reason idk the for loop goes for only one iteration and gives back one character that obviously doesn't match with the password

#

And really the only thing that could fail in change password is wait for password that anyways didn't work before for what we needed with Master password

#

Well I say another issue

#

There's a double ";;"

#

Well double ";" I mean

#

But well I don't think that's it either

wary cloak Aug 22, 2022, 2:31 AM

#

Now that I think about it, it's strange that it didn't warn me about the ";;" Considering how C++ cries to me for the smallest thing

old mango Aug 22, 2022, 2:49 AM

#

Ohhh i see what the issue is

#

Read over that function again, and tell me where the for loop ends

#

@wary cloak

old mango Aug 22, 2022, 2:55 AM

#

wary cloak Now that I think about it, it's strange that it didn't warn me about the ";;" Co...

Nah, C++ is fine with that
It actually counts the second semicolon as an empty statement
Like when you do

while(!Serial.available())
  ;

#

Which is just saying "while serial is unavailable, continuously do this <empty statement>"

wary cloak Aug 22, 2022, 3:02 AM

#

Oh

wary cloak Aug 22, 2022, 3:02 AM

#

old mango Read over that function again, and tell me where the for loop ends

Ok let's see

#

Oh

#

The return is in the for loop I need an extra bracket

#

Well I have to go to sleep for today but tomorrow I will try that and hopefully that solves the issue and that would be it for now

#

Tomorrow I tell you "it worked" Or "this happened"

wary cloak Aug 23, 2022, 12:18 AM

#

@coral geyser think you'll be tonight to make the pendrive thingy?

wary cloak Aug 26, 2022, 12:30 AM

Hey I didn't update you

#

It worked

#

I also had to change some other things but messages only it's perfect now

#

Now the project has a technical issue not a code issue so I will have to wait

#

Tho

#

The ultrasonic sensors code is kinda some more or less

#

Now I maybe will start the other the one with the SIM and stuff

#

Ideally I won't need help until reaching the final part with the SIM module

#

Because that's new, tho maaaaybe if I could figure it out on my own would be cool

#

In any case I'll be asking

wary cloak Oct 8, 2022, 2:45 AM

#

I will need help I'm installing this abstraction on a new pc and got stuck here

#

I had already re installed rust and followed the instructions up until that point

#

but for any reason
