Hello everyoneI do not understand how to use the STACK_SMBUS_ExecuteCommand callback function provided by the SMBUS stack (See picture below). The function is called either in receiving data or transmitting data (from the device point of view). Due t...
I can transmit data in this code, but I cannot receive data with an interrupt. Can you help me?Code:#include "main.h"#include "kibar_nextion.h"#include <string.h> UART_HandleTypeDef huart4;UART_HandleTypeDef huart3; uint8_t main_buffer[13];uint8_t pu...
Hi everyoneI have some issues using the X-CUBE SMBUS stack from ST.Issue 1:I have an issue with the alert response process. I am using 2 WB55 NUCLEO's. One is defined as host, the other is a device. Now when the device pulls alert signal low the mast...
Hello,I have a custom pcb with STM32H747XI and a DSI LCD. Everything is on M7 with PWR_DIRECT_SMPS_SUPPLY.The issue that I am facing is that I can't write any data on lanes. Both Positive and Negative are on 1.44v constantly.I tried to be as close as...
1. CubeMX only allows HAL or LL for SPI and other peripherals. STM32C031C6 itself provides the good SPI clock rate. SPI LL API function only allows two-byte R/W.. The slave STPM34 Meter IC requires 4-Byte SPI R/W. So we have to choose HAL SPI API ...
I am new to embedded programming and very recently got started with programming the STM32F407G Disc-1 board with STM32CubeIDE(1.12.0).I typical register level program for LED blinking:Blinking the on-board LED - LD4. int main(void){uint32_t *clk_reg ...
I use NUCLEO-F722ZE and STM32CubeIDE.When I set SDMMC1 to SD 4bits wide bus, the RCC shows a warning “partly disabled conflict with : SDMMC1 : SD 4bits wide bus”. At this time, when I wrote a program on the board and operated it, “FR_DISK_ERR” occurr...
Hi, I am using STM32F746 controller for development. So my hex file size is too more then controller flash memory. So I am trying to use Moving internal flash data to external flash Making external flash work as internal.So kindly explain how to achi...
Hi, I am working on STM32F1 family and implementing LIN communication. I found the function HAL_UARTEx_ReceiveToIdle_DMA() that is very useful to handle variable incoming data. But I have a problem that this function only works first time, but not ca...
I'm simply trying to do:res = f_open(&fil, "file.txt", FA_CREATE_ALWAYS | FA_WRITE);but nothing is created despite the return message. Could it be my SD card? I'm able to read from it in 4B mode.Any suggestions would be gratefully received.
