I tried to change SPI1 to SPI4 in the LL example code.My problem is I cannot detect any signal on the CLK or data pins.void Configure_SPI4_DMA(void) { /* DMA2 used for SPI4 Transmission * DMA2 used for SPI4 Reception */ /* (1) Enable the cl...
Hello, is there any way to use EXTI simultaneously in different ports with the same pin number?Examples for MCU STM32L071CB:Using PA4 and PB4, orUsing PA10 and PB10, orUsing PA6 and PB6, and so on
Android version fails to connect with "error during the connection with the node XYZ". I have tried both latest version available in Google Play Store (v4.14.7) and the other version (v4.14.4) available on ST Micro website. Does anyone have solutions...
HAL_PWR_EnterSTANDBYMode() will still wait properly, but HAL_PWREx_EnterSHUTDOWNMode() will immediately return to RUN mode.What do you think is the cause of immediate wakeup?As shown below, the only code difference is whether to enable HAL_PWREx_Ent...
Using STM32F429ZIT6 - NucleoHere's what I observe on PE9. Counter Mode is upcounting, PWM Mode 2 At first, I thought there had conflicts in the parameters (OCMode, OCPolarity and OCIdleState) of MX_TIM1_Init() function static void MX_TIM1_Init(void) ...
Today my STM32H747I-DISCO board arrived. Currently faced out an issue about the specification on the website from ST:https://www.st.com/en/evaluation-tools/stm32h747i-disco.htmlThere is a 512Mbit SDRAM mounted on the board instead of 256MbitPlease ca...
Have a file and I am trying to transfer it to SAI2. For some reason ???? I am not getting into the DMA Callback. DMA is in normal mode. Can anyone shed any light on this? /* USER CODE BEGIN 2 */ HAL_DMA_RegisterCallback(&hdma_sai2_a, HAL_DMA_...
TIM1 is slave of TIM2 and get triggered correctly when Encoder count reaches sConfigOC.Pulse = 200; However, the output pin TIM1_CH1 (PE9) stays high.#include "main.h" TIM_HandleTypeDef htim1; TIM_HandleTypeDef htim2; UART_HandleTypeDef huart3; ...
I have tried everything to clear this error. Does anyone know what I am doing wrong and how to fix it? The error if pointing to the HAL_UART_Transmit_DMA call.uint8_t SPI_data[SPI_Buffer_Size] = {};HAL_UART_Transmit_DMA(RS485_1, SPI_data, strlen(SPI...
Hi everyone,I'm working on a custom display board with a STM32H7A3ZI MCU. I have the same QSPI Flash than the STM32F769I-DISCO board, which is the MX25L51245G, except that I use the 16 pin package for my custom board. The H7 has an Octospi interface ...
