PWM Pin Level

Hi All,I'm using stm32f1 series. & truestudio.I want to set the PWM pin "High" when pwm does't starting pwm.But when i initialize the pwm, pwm pin is "Low".How can i set the pwm pin "high" when initializing.

Porting ExtMem_Boot to STM32746G-Discovery

Hello Could someone please tell me if it's possible to port the ExtMem_Boot Template for the STM32F7508-DISCO to STM32746G-Discovery board ?Or did someone already port it and could share his code ?Thanks in advance Raphael

Arm Assembly Timer İnterrupt

Hi everyoneI'm trying to write the timer interrupt code I wrote in C (pa3 pin blinks at 10 ms intervals) with arm assembly language, but it doesn't work.I don't know exactly how to do the timer interrupt in assembly language.I tried to write my own c...

Hello everyone. I wanted to know how can I put the stm32f4xx in sleep mode and wake it with internal interrupt. i want it to go in sleep mode for 2ms and be awake for 2ms.

Scanning multiple channels using polling on STM32f401Re

Dear ST community,I am using ADC to measure different voltages and I need a total of 15 channels and I need to measure ADC in a polling mechanism. When I useHAL_ADC_GetValue(&hadc1);It gives me value for only one ADC channel I am unable to receive va...

Offset correction to results from ADC conversion properly not happening

As per the below screenshotThe result of regular channel data is to be subtracted with an offset value. But this works only when the regular conversion sequence starts with an odd channel number and offset correction is not happening when the regular...

Hi, I am using the NUCLEO-L152RE. I am trying to run UART example sending some char's to the Teraterm but can't see any char there. I am using the USART2 (expected to see the char's in the USB STlink virtual com. Do I miss somthng? Regards

I2S : Interface with STM32. Hello, I have a processor type STM32L433RCT6P, after download the datasheet, I don't know how to (physically to wire the pinout) connect to the processor. I think it'll have only 3 pin

DMA UART transfer error "HAL_DMA_ERROR_TE"

Hi all,I'm trying to setup a DMA TX UART code using STM32H743VI MCU. The problem I'm facing right now is every time I call HAL_UART_Transmit_DMA function, I get a HAL_DMA_ERROR_TE in my DMA error call-back. The actual line of code is as follows:char ...
