TMC2130

[anfractuosity]

Hi, I'm wondering if anyone could possibly point me in the right direction, I couldn't tell if the TMC2130 is supported, I've been trying
to enable doing the following (I'm very new to grblHAL, so possibly I'm doing something very wrong here).

#define SPI_ENABLE 1
#define TRINAMIC_SPI_ENABLE 1
#define TRINAMIC_ENABLE 2130
#define TRINAMIC_MIXED_DRIVERS 0

#define SPI_MISO_PIN       4
#define SPI_MOSI_PIN       3
#define SPI_SCK_PIN         2
#define SPI_CS_PIN           5

I get the following over the USB UART -

[MSG:Warning: Could not communicate with stepper driver!]

Any ideas would be most appreciated!

I actually have 3x TMC2130 modules connected to the RP2040, with 3 different CS pins, I wasn't sure if it's possible to specify 3x CS pins though either.

(I've verified the hardware works by a micropython example I made)

The low level code required for TMC SPI drivers has not been implemented yet since there are no boards available for them.
With low level code in place both single and dedicated CS lines is possible.

Other drivers has such low level driver code in place that could be modified for the RP2040.
FYI the reason that it compiles without it is that the interface is implemented as weak functions.

Here is one implementation, will you be able to port it to the RP2040?

Thanks a lot for your reply and information. I'm not sure I have the skill to port it, I will see if I can take a little look though.
