I got an M5Fire and a QR-Code Scanner with the Atom Lite. I want to send the results of the QR scanner to the M5Fire via UART, and I connect them with a Grove cable via Port C on the M5Fire (which I bought last week).
I can make it work, BUT
- it only works when I download it via UIFLOW, I can not test it live from UIFlow, because then it runs into an error
- The setup to make it work is different from what I would expect (Tx and Rx have to be switched).
You can see the screenshot attached, which makes it work:
If I run it "live", I get the following error though:
Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled.
Which I saw being attributed to the pins being used otherwise.
Can anyone help me shed some light on that?
Thank you so much
