Hello,I am testing the processing time of a STM32L476 chip on a Nucleo board.Here below is the code:uint8_t algo_principal(s16 xin, s16 yin, s16 zin) { uint8_t retour; uint32_t i; uint32_t test; test = (uint32_t )xin + (uint32_t )yi...
How can i change the Frequency/Speed by which the Data is transfered to the UART TX pin?
What are the frequency that stm32 microcontroller peripherals work on ?
Hi, guys. I'm using the STM32L4 discovery (MB1184C) board to test DAC (Pin PA5).I use Keil uVision 5 to debug the code.I noticed the Timer trigger option and I want to use this.I want to put this MCU to sleep at the main function's while loop.Periodi...

Hello,Iam trying to implement a phase shifted 4 channel PWM on STM32F302R8 .The PWM signals should look like the first picture. I use CH and CHN complementary PWM generation with deadtime insertion. PWM mode ist asymmetric PWM Mode 1 for both channel...

Hello,I try to setup ADC1 and ADC2, but I don't get the timing values given in reference manual and data sheet. I work with STM32H743 NucleoI have setup RCC to clk ADC with 36 MHz from PLL2P. I checked the frequency at master clock out 2 on PC9. To i...
Good day. Faced such a situation. I want to get at the output of the DAC zero level (writing to the register is trivially 0). That's just absolute zero does not work, on the output of the microcontroller there is somewhere around 70mV. The influence ...
I am using Timer6 on STM32F7 series MCU. As soon as I enable the Timer, UIF bit is set in Status Register which is rc_w0, means it gets cleared by reading or writing 0. Then Execution goes to ISR. In ISR when I read the Status register and Try to cl...
