Hello everyone, I am a beginner on STM32F4. I want to using DMA for receiving data via USART. But it doesnot work, please help me to solve the problem. Here is my code:void USART2_ConfigDMA(void){ DMA_InitTypeDef DMA_InitStructure; RCC->AHB1ENR = ...
I want to use DMA on my stm32h7 board, but i can find which channel is used for what protocol ect.
I'm using F401 that is connected to an A\B encoder and the A\B are routed to TIM2 that is set to work in encoder mode and it is counting the encoder movement as expected.I want to use another timer that will work as TIM2 slave for measuring the encod...
Hi,Being new to QSPI technique I have to ask for some help to find out if I have misunderstood the whole concept.Our target is to have two QSPI flash memories and run the code from the first one (xip) and use the second one for data storage to be use...
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...
