Hi,
I have this project in which the uno reports via serial to the pi. The pi runs a python script.
The problem I have is this: If I connect the uno after the pi has started the serial messages come through just fine. If they just start together (the uno just up and running immediately) then the messages come though corrupted. Sending a reset message to the uno does not help. Any ideas?
Cheers,
Uri
Without seeing your code, how can we know?
A common problem is PC code that does not allow for the Arduino to reset when the serial port is opened.
Have a look at the code in this Python demo
