I found an application note described about the sinusoidal wave acquisition using 10bits ADC and 2 DMA. My question is how they display the reconstructed waveform? by UART? or by DAC?Below link is the application note AN4173https://www.st.com/conten...
Dear all， I am using the usart2 of the STM32F767 to implement the Modbus function. I used the Receiver timeout interrupt to detect if a piece of data is over. However,sometimes a timeout interrupt had occurred. when data is still receive. I set the ...
I am leaning to program the H743ZI and have a simple application where the user leds blink at a certain rate given by a delay produced by a for loop.When the code is uploaded, I get the desired rate. If I disconnect and connect the board again, the p...

Hello,I've taken the code from the Timer cookbook example TIM_ExtCLK_ETR and modified it slightly for my purposes. I removed the DMA transfer and am looking directly at the TIM2->CNT variable at a 1 second interval for right now. In this case, I'm...

I have STM32L496QG soldered on my PCB. I can use only Boot Loader via Serial COM port. I tried to use ST's Flash Loader Demonstrator, it doesn't work. I need some Windows -based software. What can you recommend?
Hallo everybody,i would like to generate analog signal (0-5 V) via DAC but the problem is the maximam voltage is 3.3 V . ist it possible to change some configuration to generate an analog signal with maximam voltage from 5 V? thanks #DAC #[Analog an...
I do not know if and what I am doing wrong. I am using CubeMX and a Nucleo 64-Board. This is the while inside the main:while (1) { if(HAL_ADC_PollForConversion(&hadc, 1000) == HAL_OK){ adc_value[i] = HAL_ADC_GetValue(&hadc); media += ((f...
