Can you hook up a logic analyzer or Oscilloscope to determine a possible baud rate. It may not be a standard one. The standard ESP8266 for instance starts at a speed of 74880 baud, just to switch then to 115200 baud with the start of Micropython. With Windows/Putty, you can set non-standard baud rat...
GPIO0 is Pin(0), GPIO2 is Pin(2). Both must not be 0 upon boot for normal opeartion, but pulling them up for I2C is no problem. So your code snippet would e.g. be from machine import Pin, I2C scl_pin = Pin(0) sda_pin = Pin(2) i2cbus = I2C(scl=scl_pin, sda = sda_pin) I used scl_pin and sda_pin to poi...
