Mesa card emulation in microcontroller

Thanks for the link, looks promising

The STMBL Servo drives also act like Mesa devices. In that case they are a Mesa Smart-serial device, and use an STM32 microcontroller.

This means that you can send motor positions as a floating-point number on an all-digital link, and get the actual position back in to HAL in the same way.

Interesting, I must admit I don't really understand the serial device part, I assumed this was for a serial device out of the Mesa card to other peripherals.

Hi andypugh,

Just re-read your post after reading a bit more about the serial interface, does the servo connect over ethernet, and is it set up as a mesa device?

Thanks

Sorry, I am probably confusing things,

The STMBL contains an STM32 and plugs in to a Mesa FPGA card just like a Mesa Smart-Serial card. In fact as far as the system is concerned it is a normal smart-serial card.
I think that the smart-serial cards from Mesa use a dsPIC rather than a µP like the STM32.

Yeah, I think I guessed correctly, smartserial allows peripherals connected to a Mesa to be controlled by LCNC.

I'm interested in getting LCNC to communicate with an STM32 as if it was the FPGA, DOIT commands etc.
