#I2C Error in Adafruit DC and Stepper Motor HAT for Raspberry Pi
fresh grotto
I have also been advised to use alternate code.
Define kit = MotorKit(i2c=board.I2C(), address = 96)
fresh grotto
Soldering.

Tried using address as parameter

import time

kit = MotorKit(i2c=board.I2C(), address = 0x70)
kit.motor1.throttle = 1.0

kit.motor1.throttle = 0

Here is me running the blinka test code
This is the code:
import board
import digitalio
import busio
print("Hello blinka!")
# Try to great a Digital input
pin = digitalio.DigitalInOut(board.D4)
print("Digital IO ok!")
# Try to create an I2C device
i2c = busio.I2C(board.SCL, board.SDA)
print("I2C ok!")
# Try to create an SPI device
spi = busio.SPI(board.SCLK, board.MOSI, board.MISO)
print("SPI ok!")
print("done!")

you need to use backticks, not smartquotes to get the code blocks to format correctly
i looked at your screenshots, and for some reason the Python code isn't detecting the I2C devices that your i2cdetect commands are, which is kind of odd. i haven't touched Raspberry Pi in quite a while, so maybe someone who's more familiar with it can help

Okay, I’ll try #help-with-linux-sbcs

you can link the thread to make it easier to find when you do post there

Attempted reflow. Same issue

@novel sedge , may I have help?
novel sedge
do you know how to run python interactively? to type commands in REPL?

do you know how to run python interactively? to type commands in REPL?
Do you mean typing $ python3 into the console to run code there?
And for REPL, I'm not familiar with that
novel sedge
yep
that's it
REPL is just the >>> prompt
run python3 and the try the command interactively
import board
from adafruit_motorkit import MotorKit
kit = MotorKit(i2c=board.I2C())
one line at a time?
novel sedge
yep
novel sedge
unfortunately it's likely still a connection issue
that Remote I/O error is pretty much always connection related
is it still showing up reliably in a scan?
fresh grotto
unfortunately it's likely still a connection issue
Are there specific pins I should focus on?
fresh grotto

novel sedge
these two
try scanning also via REPL
exit and relaunch python3
then:
import board
i2c = board.I2C()
i2c.try_lock()
i2c.scan()
syntax?
fresh grotto
Is that supposed to detect i2c addresses?
fresh grotto
How come that is empty but the other command returns 60 and 70 address?
novel sedge
not sure. but potentially another indication of marginal connections.
fresh grotto
Could I test I2C with another device or does it have to designed for it?
novel sedge
do you have some other I2C device?
fresh grotto
I'm not sure what that may be. The only HAT I have is this Motor HAT. I've got an assortment of components like Ultrasound sensors and small LCD screens
I also have a Pi Pico and an RPi 4
fresh grotto
It's getting late so I'll respond fully tomorrow but they are these
novel sedge
not i2c
fresh grotto
hahaahha I realised I had plugged in the HAT with only one row of GPIO pins when doing those tests
fresh grotto
```python
import board
from adafruit_motorkit import MotorKit
kit = MotorKit(i2c...
Same error.
fresh grotto
yep. addresses would be in the `[]`
Yesss!!!

looks like addresses are showing up in REPL scan now. are things working now?
