STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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-...
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 ...
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...
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 variation...
SPI receive funtion not working correctly. Only one time is working, where is my mistake ?thanks void SPITransReceive(SPI_TypeDef* SPIx,uint8_t data,uint8_t *pbuff,uint8_t dataSize){ while(dataSize > 0){ while((SPIx->SR & SPI_I2S_FLAG_TXE) == R...
