[Solved] Help with LCD I2C

Post by Panos45 » Thu Sep 03, 2020 12:33 am

I have recently picked up micropython and I am trying to connect an LCD 1602 with PCF8574 backpack for I2C on an esp8266. I have found 2 modules on GitHub, but I have no ideas how to import them on to my Sketch. Do I just save them in the tree directory? I am using uPyCraft.

I'm not sure how uPyCraft works, but you will need to copy the files to the device. I recommend either rshell (https://github.com/dhylands/rshell) or pyboard.py (http://docs.micropython.org/en/latest/r ... rd.py.html)

Problem solved, I just had to copy all the code to a new file and upload it to the esp, but my main problem was poor cable connections, since I was getting unstable address readings on the I2C bus. Changed the cables and works like a charm! uPython looks much better than Arduino! Thanks for the help!
