I2C timeout with OLED display on Pico

in General • 8 years, 12 months

Now I have tried my Heltecs and I cant get them to work. Shorted pins 19-20 on one of them, and Im using 4k7 pull up resistors on SCL and SDA. Tried both 3.3V and 5V. I get "Uncaught InternalError: Timeout on I2C Write BUSY".

The screens works great with an Arduino.

DrAzzy, I have a Heltec 128x64 I2C screen that I have been using with Arduino. It took me some time to get it to work, because it didn't send and ACK back that most drivers expected. Could this be a problem here? I haven't tested it with my Espruino Pico yet...
