ADC Timer Trigger
My ADC1_Data Register is null. I can't understand why it is. Can u help me?#include "main.h" #include "SysClockConf.h" uint16_t values[256]; // MY CLOCK IS 170 MHz." // STM32G431 // READ_BIT() Fonksiyonu void GPIO_Config(){ RCC->AHB2ENR |= RCC_AHB2E...
UART DMA
I am using STM32H743I used uart's DMACheck whether data has been received through this functionBut there is no data in the buffer. Why the hell is this happening?And, of course, I changed the linker start(0x24000000) and end address(0x2407FFFF) of th...
I am working with STM32G4 NUCLEO and STM32CubeIDE. Created a project to use FDCAN2 (classic mode) to evaluete CAN comm in polling mode. On FDCAN2 CAN messages are only received when I additionally activate FDCAN1.
FDCAN1 has a basic parameter 'Clock Divider' set to 'Divide kernal clock by 1'. FDCAN2 does not have this parameter. In library function HAL_FDCAN_INIT(...) there is a statement: /* Check FDCAN instance */ if (hfdcan->Instance == FDCAN1) { /* Confi...
Unable to use SPI2 on PA12 PA11 PB15 with STM32H743
Hi,created some SPI2-slave code running on PB10(SCK), PB12(NSS) and PC3(MOSI) without problem. Needed to move SPI2 to other pins as PB12 will be used by RMII in later design. Decided to use PA12(SCK), PA11(NSS) and PB15(MOSI). SCK is running at 12.28...
STM32WL55 using XO
Hello to everyone,There are many examples that come with the STM32WL55. Especially LoraWAN examples are very useful. All examples are made to work with TCXO and are not very obvious to those working with XO in code.We made a board with the STM32WL55C...
Which GUI language should I choose to cooperate with STM32?
Hi!I need to make a GUI app that checks the connection between the computer and STM32, sends commands and receives messages etc. I don't have much experience in writing windows apps, so could you tell me which programming language is best to use, and...
Blocking of the program flow with data reception with interruption through the USART port
I am having problems receiving data through the USART port. It enters the interrupt well but when it enters the HAL_UART_Receive function the program is blocked in the UART_WaitOnFlagUntilTimeout function. As I understand it, this works, it waits unt...
How to disbale All interrupts except systick timer interrupt ?

I2C error handling
I am developing with STM32F030Cx, using CubeMX for the configuration. The application is basically a simple full cooperative scheduler (no RTOS, no context switching) that calls several "tasks" in a sequence. I am using the blocking functions of the ...
