ST Motor Control workbench serial interface specification?

[Jolof.1]

Where can i find the serial port communication protocol specification, so i can control a motor over the uart, without using ST Motor control workbench?

Dear Jolof.1,

this specification is indeed missing.

Do you have any particular question on this topic we can try to answer?

Thanks,

Claire

I got the specification from another person at ST by email, not from this forum..

​thank you! have you implemented / tried already?

[Jolof.1]

You are welcome Claire =)

Lmazz.1 : Yes i have implemented "motor control protocol (MCP)". In controller that controls two motors. Works fine, a hint is top read out the fault flags, in case a fault occurs the motors stops and the flags needs to be cleared before you can continue running the motor.

​Awesome - are you using any of c library to handle the communication protocol or you just coded your own?

[Jolof.1]

Made my own, could not find any library for it.

[Lmazz.1]

what about this? do you think is possible to use?

[Jolof.1]

Yes, not sure. Could be that it's only the Slave-end support for the protocol. Not the controlling master end?

I never dived deep into that code..
