Toggle led using external interrupt from push button

I want to toggle a led when an external interrupt happened. But I could not. That's my code using keil mdk for stm32f103c8t6 Any help, please? #include "stm32f10x.h" void GPIO_Config (void) { RCC->APB2ENR |= (1<<2); // Enable GPIOA clock GPIOA-...

TIM1 break interrupt and TIM9 global interrupt false 0 0 TIM1 update interrupt and TIM10 global interrupt false 0 0 how to enable tim1 interrupt since there is no direct global interrupt controller using stm32f401ccu6

Resolved! I am using STM32L031F4P. I want to use it Programmable Voltage Detector to detect the voltage of its power supply. I am not finding any library to use. I want to have some coding help and its library file.

Resolved! How to config the FIFO Threshold of OCTOSPI

According to my understanding, I can read/write data directly through the "DR" register. Why do I have to set the FIFO Threshold value? How to use the FIFO correctly during the reading and writing procedure? And another question is that How to set ...

STM32L4P5 - I understand that a "load multiple registers" takes multiple clock cycles to execute. can an interrupt break in the middle of this or does it wait till after the set of loads is complete?

Resolved! Possible to use TWO circular DMA buffers for same I2C rxd?

Hello,I would like to use TWO circular DMA buffers for ONE I2C interface.Depending on received address byte, in the ADDR interrupt I would always enable the correct circular buffer (disabling the other one - so at one time always only ONE buffer is a...

I am using a STM32G030F6P6. I would like to know if I can use printf for debugging on USART2 (PA2, PA3) or USART1 (PA9, PA8). I believe both are valid, but I would like to check. BR Gilberto

Resolved! Can't program STM32G031J6-DISCO: “No device found on target"

Hi, I am trying to use an STM32G031J6-DISCO board to get a grasp on the 8-pin STM32G031J6 MCU that I consider for building small IoT sensors (for teaching purposes). I am new to STM32 products (or ST MCUs in general). I managed to write a few variati...
