Re: I2C LCD screen with Raspberry Pi Pico
Posted: Fri Feb 12, 2021 10:05 pm
Hello, could I get some help please?
I'm trying to get a crowtail ic2 lcd to work on the pico, it has the MCP23008 module, so pyb_i2c_adafruit_lcd.py and pyb_i2c_adafruit_lcd_test.py should work for me right?
I tried to convert it to pico friendly from pyb, and I get no errors on running it, but the lcd doesn't seem to recieve any commands, it's not backlit but the top row is full. I tested the esp8266 files just in case, but didn't seem to work either. I've used the lcd on arduino before, so there shouldn't be any hardware issues.
I'm not sure if I have the i2c commands correct, I tried to copy from them from the esp8266 files. I would appreciate pointing out the errors.
Here's a link my code: https://github.com/EMartti/crowtail-i2c ... /tree/main
Thank you
