trim sand
im currently trying to get my input shifters to work (3 Shifters daisy chained like the wiki shows). My problem is that regardless of which number i selected from the 24 numbers i have due to the shifters only always one physical button works. even if i have different functions with different pinnumbers(not 100% sure how to call this number) only one physical button works, that somehow controls both digital buttons in the sim. what am I doing wrong?

Can u show us the wiring diagram of ur setup
trim sand
distant tundra
Have u tried to connect all CE pins to gnd?
trim sand
you mean pin7?
distant tundra
I believe its pin 15 of the SR
trim sand
distant tundra
Yes that one
trim sand
pin15 is grounded at all 3 of them
distant tundra
Why is the SER from ur master SR connected to gnd?
trim sand
Why is the SER from ur master SR connected to gnd?
the right one is the master
its connected as its said in the mobiflight wiki
distant tundra
Still i belive SER is not supposed to be connected to gnd
mighty pebble
yes in te first SER goes to gnd
trim sand
so my curcit is correct?
distant tundra
mighty pebble
if the green line on the button is GND is corretc
distant tundra
I did mine like that and it works just fine
mighty pebble
don't mix thats for outputs
distant tundra
Oop misread that one
trim sand
if the green line on the button is GND is corretc
the green bottom line is ground yes
distant tundra
I meant the 2nd one
mighty pebble
don't forget the pull ups resistrs
distant tundra
distant tundra
Ser is connected from SER slave to master Q7, u didnt have to connect it to ground
trim sand
so if i select button 6 in mobiflight it uises button 24 for some reason
mighty pebble
did you try first with 1 IC?
trim sand
no
mighty pebble
please share the complete picture with the button part
i don't know why I'm seeing a +5V there in the midle
mighty pebble
did you double check you dont mix the 3 pins going to the arduino?
mighty pebble
check with only one IC
pin 9 of the left most to the arduino
what you get on the debug windows?
trim sand
so it does recognice the inputs?
oh no wait thats just the clock going through
so i dont know how to explain properly but, when i click one specific physical button the clock goes through once and it looks like in the screenshot. when i press any other physical button nothing happens
distant tundra
What kind switches are you using?
trim sand
6x6mm tactile push buttons
distant tundra
May i see how you wired them
trim sand
you mean this?
distant tundra
Its kinda difficult to comprehend it from the schematic
Its like u have the voltage connected to both of the poles of the switch
trim sand
one of the buttons leg is ground and the other one is connected to a pull up resisitor and a pin at the register
mighty pebble
show the press, that is normal when you start running
with each press you get that log?
trim sand
mobiflight seems to only recognice the 24th button from the unput shifters
so only the last button from the last shifter
or if im pressing the 24th button mobiflight things i have pressed all the 24 buttons at the same time
thats my understanding of the logs
distant tundra
Would it be correct if its like: cuz if u swap the resistor with the Vin, it make all the switches On
mighty pebble
so only the last button from the last shifter
that's what i think you mix data and latch
trim sand
Would it be correct if its like: cuz if u swap the resistor with the Vin, it mak...
like that
trim sand
that's what i think you mix data and latch
ill check
distant tundra
Ohh thats prolly why
The pole separation for tactile switches is vertical
Youd turn them on if its wired like that
The SR pin must be with the GND
mighty pebble
Would it be correct if its like: cuz if u swap the resistor with the Vin, it mak...
push buttons dont need vin
distant tundra
This is basically how SR read each pin input if you wired it like that. If SR pin is connected to Vin, its on, else its off. Try connecting all the SR pins to the GND side instead of the Vin
mighty pebble
please just use 2 pins of the push button 1 to gnd and other to the IC input
doesnt need vin

ive found the problem
for some reason the dlock tracer from my pcb seems to have been damaged so there was no connection to the arduino. ive bridge the tracer with a wire and now it works fine. i dont know why the tracer isnt working becuase at all 4 other pcbs that i have (which are 100% identical) the tracer works just fine. i guess i was just unlucky here but whatever now it works with that small walk around
thx for your help anyway
