I am using UM1594 user manual for 6 step sensorless bldc motor control. There is psuedo code. It's quite well but i can't understand some points.

What's the mean of this sentence?

"Lookup TIM1_CCER value from table based on phase to commutate bridge" What should i do? in page 5.

Or is there any other documents to understand this topic?

Six-step sensorless BLDC motor drive example software for the STM32™

Dear @Samet Yazıcı​ 

Welcome to the STM32 Community

Could you give more details to the STM32 Community about your setup -the material you use- ?

(HW and also SW: CPU(s), tools and versions, board(s), motor(s) and so on)

And more especially did you use STM32 MC tools or what version of those tolls you use (such as MC_suite, STM32 MC Motor Profile, STM32 MC SDK, STM32 MC Workbench, the used example, the origin of the base of your application source code, and so on)?

Best regards

Dear @sametyazici,

Looking at the document, it is a very old one (2013) which is not aligned with our latest 6-steps examples, nor with the current FW architecture and communication feature.

So, we will recommend you to use the MC SDK, using one of the 6-steps examples as a good starting point.

Best Regards,

PBo
