TMC9660 TMC API Not out yet

Thank you for your inquiry. MentioningThomasErnst for assistance.

Please provide an answer to this question - we might switch from TMC4671/TMC6200 to the TMC9660 during development, but the missing API is a reason against doing so.

More specifically the question is, whether a C API for the TMC9660 in register mode is actually planned to be provided, and if so when it will be released.

Another question is whether a C API for the TMC9660 in parameter mode is also planned to be provided.

ThomasErnst any follow up?

Hello, quite interested in this as well. Any follow up for this? ThomasErnst 

Hello, I checked the GitHub repository and saw that the TMC9660 was recently added. UART only, but both parameter and register mode seem to be supported. 

github.com/.../TMC9660

sorry for the inconvenience:  
I have use and integrated in my MCU the TMC-API of the TMC9660 with the UART 'C' functions:
I am able to send for the bootloader command 8 byte: tmc9660_bl_sendCommand (uint16_t icID, uint8_t cmd, uint32_t writeValue, uint32_t *readValue)    <--  The TMC9660 Answer OK!!!!

While for the 9 byte parameter: tmc9660_param_sendCommand (uint16_t icID, uint8_t cmd, uint16_t type, uint8_t index, uint32_t writeValue, uint32_t *readValue)   <--  I NEVER GET A RESPONE from the TMC9660 and the BLDC motor don't Start!!!!  

My boot is probably not ready? Do I have to go out? Am I doing something wrong?   Have you ever managed to get response from the 9 byte parameters??  

Thank's
