Hi all,
How to reset i2c bus whitout reset mcu?
Thanks
Kind of guessing here, but you could see if this works.
- lambda: |-
Wire.end();
delay(500);
Wire.begin();
Doesn’t work. Wire.end() - not allowed.
I working on the project where several board with I/O Expander connected by I2C. Once one of the board lost power (I was not planning to make back-up power supply for it) and power is restored. I can’t control outputs any more. I wish I can re-initialize expander, but can’t find solution.
