how to understand the code of single shunt resistance current sampling about FOC 2.0 version, could you give me a code description document about this part in detail,or communication with me about BLDC/PMSM control，thank you very much!

Dear @Wfang.1​ 

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 (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

I am using STM32F103RBT6/STM32F103R8T6 base FOC 2.0 version to develop vector control of BLDC. I can achieve three shunt current sample,but can not achieve single shunt current ,which the related code in the stm32f10x_svpwm_1shunt.c file. I can not fully understand the logic of this file and the purpose of some variables(such as MINTIMCNTUPHAND,MIDTIMCNTUPHAND,CH1NORMAL,CH2NORMAL,etc. how to modify these variables in different application). I am developing this project base on keil MDK environment, and do not use STM32 MC tools. I bought a motor control board online to verify FOC strategy base on single shunt current sampling. If the strategy could be verified, the code would be transplanted to our product.

​

because of the little information about single shunt current sampling base on ST, I need the support of you. how to understand the content of stm32f10x_svpwm_1shunt.c file, that's my appeal.

Best regards

Additional remarks: after several days of understanding, I found some problems with my current code which could not achieve single current sampling, so I wanna get full source code about the single shunt current sampling to realize FOC control. If possible, I Will be very happy. Thank you. Of cource, a description of this part of the code is ok.

Best regards
