Not as far as I know, but it might be a fairly simple thing to create.
It need to create HAL pins then gather the data from wherever, and put

That appears as a COM port, so would probably be conveniently
interfaced by a HAL driver

I don't think you are going to use an ADS1256 for
servo feedback. 30khz sounds good, but when you
look at the datasheet fine print, there are caveats.
First, the inputs are multiplexed, so cycling the
multiplexer drops your 30khz data rate to an effective
4.3khz rate. There is also a 0.2msec
Is there an easy way to bring CANopen information into LinuxCNC?
I have a number of CANopen modules that have I/O that would work well as tool
changers or displays for status information like Control Cabinet voltages etc.
Under Linux CAN messages are available via SocketCAN. So it's easy

The boards always seem to have lots of unpopulated pads. I assume that
these are for

I really don't know yet how much work it would be to
port STMBL to the Pico. A stock STMBL drive, with
an STM32F405VG processor has four analog inputs
(as far as I can tell). Those are 12bit, and can be scaled
in stmbl's local hal. I haven't investigated the sampling
rate for those conversions.

I finally succeeded in getting the STMBL code on a STM32F407
Discovery eval board talking to a Mesa 7I90 via sserial. The
final issue was assuming the wrong pin for sserial tx on the F407.
Here is my final summary of everything necessary to replicate
what I did, for anybody else trying this.
