Hi!I am using STM32F031 MCU as my BLDC motor controler,I using "gcc-arm-none-eabi-10-2020-q4-major-win32.exe" as compiler and compile with -Ofast option.However,when i using HAL_ADC_Start_DMA(),the ROM of code almost fill up the MCU.is it normal?TURN...

Hi!I am using STM32F030K6T6 as my bldc controller.i set up my adc as below:/* ADC init function */ void MX_ADC_Init(void) { ADC_ChannelConfTypeDef sConfig = {0}; /** Configure the global features of the ADC (Clock, Resolution, Data Alignment an...

Hi! i am using STM32F401CCU6 for BLDC/FOC motor control application.For foc application requirements, i need sampling 3 phase current in inject mode, vbus and motor temperature in regular mode.However, there is only 1 adc available for sampling. i tr...

Thank you!I found some flaws in my code and i fixed it already.It cant work buz i did some time-consuming job in adc-dma interrupt.and here is my code: HAL_TIM_Base_Start(&htim1); HAL_TIM_PWM_Start(&htim1,TIM_CHANNEL_1); HAL_TIM_PWM_Start(&htim1,T...

I found solution by myself.I have to set "Clock Prescaler" to "PCLK2 divided by 8" and everything going well! However I still can't understand why the MCU is not working at the division of 2? Is DMA clock problem or ADC can't handle that fast?

HAL_ADC_Start_DMA() consume so many ROM with STM32F031 MCU & latest GCC compiler.

TIM interrupt not firing after circular adc-dma started on STM32F030K6T6

How to setup regular mode(SW trigger+DMA) and inject mode(TIM1 CC4 trigger+IT) working together on the SAME adc in cubemx?
