* rp2040: Add spi0_gpio4_gpio3_gpio2 bus to support fysetc PITB V2 (#6683)Jessica Hunt2024-11-271-3/+24
| | | | | | | | | | | | | | | | The Fysetc PITB V2 board uses a spi bus config that is supported by the RP2040 chip, but not klipper, so this adds the relevant config to the file to allow you to run the tmc5160's on the board via hardware SPI. This resolves the issue of software spi not working on this board, which I was unable to fully understand. I have also seen other users encounter similar bus config issues with the rp2040 setting up things like accelerometers and such with this pin layout. As requested, this also uses the new convention for spi bus naming, while maintaining the old bus names for compatibility. Signed-off-by: Jessica Hunt <hunt.jessica@proton.me>
* rp2040: Only change SPI settings while peripheral is disabledKevin O'Connor2024-01-251-0/+4
| | | | | | | Make sure to disable/enable the peripheral to ensure the clock polarity is properly set prior to a change in CS. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* rp2040: implement SPILasse Dalegaard2021-07-151-0/+110
This implements SPI for the rp2040 target. All output groupings of both SPI blocks are available for use. Signed-off-by: Lasse Dalegaard <dalegaard@gmail.com>
