Hello,I wanted to put some complicated calculation into CCM SRAM in my STM32G474RE MCU. I basically followed instructions of AN4296, unfortunately I found an issue when programming the MCU.A few attaches as below:1. The link script2. The code change ...

Hello, I am working on a project that requires control the motor speed by adjusting bus voltage. The PWM width shall be consistent. The motor bus voltage is controlled by another ST micro. Is this a possible approach? What documents/ examples I can r...

Hi, I am working on a customized board powered by STSPIN32F01B, FOC is used with 3 external OPAs for each shunt resistor. The code is generated by MCWB 5.Y.4. The SDK keeps returning error code 16 or 32 after pressing the start/stop button. I have b...

Hi, I am using STEVAL-SPIN32F04 dev kit to start my learning curve on STMC. I opened a example project of MC Workbench 5.Y.4 " and simply modify the speed sensor algorithm to observer+PLL and then I got compiling errors : Error[Pe020]: identifier "st...

Hi, I am using CubeMX generates the application that contains MCSDK, The generated code has both stmg4xx_mc_it.c and stm32g4xx_it.c. I noticed that all the motor control related ISR code are coded in stm32g4xx_mc_it.c and I am confused with 2 issues:...

Hi All,I am sorry I was OOO last couple of days. I tried the code from F.Belaid. It worked well with my nucleoG4 board. I even did some further modifications, and it still worked as expected. This means that there must be something wrong with my prev...

I see, the observer + PLL algorithm works only for FOC. Not six-step control. It seems using the b-EMF to simulate the hall sensor signal input to calculate rotation speed. Am I correct?
