This is my interrupt handler...void USART1_IRQHandler(void) { uint8_t data; HAL_UART_IRQHandler(&huart1); __HAL_UART_CLEAR_FLAG(&huart1, UART_FLAG_RXNE); data = (uint8_t)(huart1.Instance->DR & (uint16_t)0x00FFU); HAL_UART_Transmit(&hua...
Hi, I want to use the STM32H743 ADC in differential mode. At first, I tried the the example STM32Cube\Repository\STM32Cube_FW_H7_V1.3.2\Projects\STM32H743ZI-Nucleo\Examples\ADC\ADC_DifferentialMode and there is something wrong in testing zero vo...
Dear Members,How can I save FIFO ?I have a psedo code :for (i = 0; i < NUM_SAMPLES_TO_READ; i++) {Read FIFO_DATA;Save IR[15:8];Read FIFO_DATA;Save IR[7:0];Read FIFO_DATA;Save R[15:8];Read FIFO_DATA;Save R[7:0];}STOP;my code : for(i=0;i<=number_samp...
I am using STM32L476.In it I am using MSI as a clock source, I want to switch to HSE as Clock Source, I want to know the best oscillator to use (4-48Hz) so that the power consumption is minimum, also I want to know if there would be any change in the...
Hello,My questions are as follows:1. Can I use DDR-SDRAM with FMC or should i use SDRAM only?2. Can I use two SDRAMs and control them with "Chip Select" pin? I want to use this SDRAM. This SDRAM is similar to used on the STM32F779EVAL board, but 512M...
Posted on November 02, 2017 at 09:19Hi all, In a STM32F0 I have configured the IWDG and every time that in debug mode I stop the MCU, then the watchtdog active and the reset is on.I read the user Manual and some post seen in this community . I use ...

I posted the list below as a reply in: https://community.st.com/s/question/0D50X0000A7WOCGSQ4/where-can-i-find-the-adc-input-impedance-of-stm32h743-in-differential-and-singleended-configurationsbut the thread seems buried and I think these items shou...
I am trying to interface with the Winbond W25Q80DV which is a SPI flash memory chip. I am using the STM32L476VG development board. To test the connection I am first trying to read the manufacturing ID from the chip. Using an oscilloscope I am able t...
I'm using the following code to read from the QUADSPI data register. (uint8_t) * dptr;*dptr++ = QUADSPI->DR;What I get is it reads 4 BYTEs from the FIFO and only returns the lowest Byte in memory pointed to by dptr. The ref manual says you can read B...
