No Raspberry Pi serial data from Arduino firmware

[GothAck]

The firmware outputs via SerialUSB but I cannot see any code to output to the pi via GPIO.

I think the HealthyPi board talks to the RPi via the serial port on the GPIO pins. So it doesn't use the GPIO per se -- only the serial port on the GPIO.

It is meant to, yes, but after flashing the latest arduino code I see no data being sent to the RPi. I've tried searching through the code but can only see transmission of the packets via SerialUSB, which IIRC is just the USB CDC serial port. The USB serial device is transmitting data just fine, just not via the RPi GPIO header.

thanks guys @GothAck and @abhas . We have moved the latest version of this repo for HealthyPi v3 to https://github.com/Protocentral/protocentral-healthypi-v3/

The code is actually sending to both SerialUSB as well as Serial
