As stated in my first post, i was fiddling with the LiquidCrystal code on arduino to intercept what was sent on the I2C bus.
With those values, using bytearray, and with this code :
Code: Select all
from machine import Pin, I2C
from time import sleep_ms, sleep_us
i2c = I2C(scl=Pin(5), sda=Pin(4), freq=100000)
for value in values:
I was able to print capital A on my LCD.
Will now try to implement bytearray in pyb_i2c_lcd.py
