Hello, I'm implementing UART protocol to control A Motor Driver Board. I need detail on "Flags" and "Status" Registers (i.e. Meaning of each bit). more How can I get Torque Data converted in nm? Thanks

Super vague, try to provide specific context

Which Board? Link to, Schematic or Name..

Which STM32 part?

What UART?

UART register bits on specific STM32, stuff that should be in the relevant Reference Manual for the part.

Hello, I've asked the questions because the relavant documentation (see attached file @ pages 161 and followings) does not contain this Info. I have two custom boards: One motor Driver Based on STM32G431 and one display Driver Based on STM32G031. I'm able to communicate using the protocol described in the attached document but some information is missing: Register "FLAGS", Address 0x01 (Should contain all the Alarm Flags): no information about the meaning of Each Bit register "STATUS", Address 0x02: Same problem as above. More: Register "Torque Measured (Iq)" Address 0x1F: How can the Number Read from this register be converted to nm (NewtnMerter) units? Thanks Alfonso Il giorno mar 29 nov 2022 alle ore 19:04 ST Community ha scritto:
