TIM1 ch1 as pwm, ch2 as cc to trigger adc caputre

On STM32F105 chip, i need to output a pwm, then adc caputure the voltage on pwm high stable level.So i try to set tim1 ch1 to pwm out, and then set tim1 ch2 as compare output wih no pwm to trigger adc capture with DMA. (CC2<CC1)Eventrually, i cannot ...

Are there any example that uses USART as SPI ? Currently I am using stm32g071kbt6 mcu for a project and i have to use USART peripheral as SPI. Other SPI peripherals on use. I found a few presentation about USART that says USART can be use as SPI and ...

Peripheral sharing with dual core H7

I am working with a dual core processor for the first time & am wondering if i need to use a semaphore to block one processor while the other reads a peripheral register?In my application the M4 is being used as a slave for some concurrent processing...

DMA for loading PWM values directly

I am attempting to use the DMA to auto-load PWM values for a motor control application. An example very similar to what I want to do is given in the RM0090, section 17.4.20 (for STM32F427). However, I'm missing some detail and can't get the DMA to tr...
