RP2040 PIO Support not available anymore

[nmaas87]

Dear all,
RP2040 posses PIO Blocks ( https://tutoduino.fr/en/pio-rp2040-en/ )which allow to generate e.g. 4 additional full-directional UARTs which are offloaded to the PIO blocks (see: https://arduino-pico.readthedocs.io/en/latest/piouart.html ).

In the past this was as easy in integration as creating an new PIO UART:

SerialPIO SerialE(27,26);

and then using it with TMC2209 like this:

stepper_driver_el.setup(SerialE,SERIAL_BAUD_RATE,SERIAL_ADDRESS_0);

however, this does not work anymore now:

X:\sketchbook\libraries\TMC2209\src/TMC2209.h:43:27: note:   initializing argument 1 of 'void TMC2209::setup(SerialUART&, long int, SerialAddress, int16_t, int16_t)'
   43 |   void setup(SerialUART & serial,
      |              ~~~~~~~~~~~~~^~~~~~

cannot convert 'SerialPIO' to 'SerialUART&'

Any way to get this working again? Thank you! :)

Last working version: 9.0.12

Good point! I just modified the code to hopefully add support for SerialPIO. Can you please try version 9.2.0 and see if it works for you? Thanks!

Yes, thanks a lot, that worked! Can confirm works again! 👍🏻
