Portenta Machine Control and PlatformIO RS485

Official Hardware Portenta Family Portenta H7
1

Hi,
we like to use an Portenta Machine Control Hardware (H7 core) with VS-Code/PlatformIO. The Blink Sketch compiles and works ok so far. But when we compile the RS485 Half Duplex Example we get the Error:

.pio/libdeps/portenta_h7_m4/ArduinoRS485/src/RS485.cpp:189:18: error: 'SERIAL_PORT_HARDWARE' was not declared in this scope

The Same sketch in the Arduino IDE compiles perfect?

Does anyone know the problem or even better the solution?

Thanks for your support

Hello nixfindus,

I got the same problem when I had selected "M4 Core" in
Tools>Boards > Arduino Mbed OS Portenta Boards
Instead of "M7 Core".
That was in the Arduino IDE, but maybe there is a similar configuration that needs to be made on this other platform?

Please let me know if you get the example working :slight_smile:
