I am using STM32F401CCU. I am trying to generate PWM, using DMA. WHen i select DMA data size as word (16bit) it is working. But when I am trying to do Byte (8 bit) it is not working. Is it because the CCRx register 16 bit wide? Is there any way I can...
Sir i am receiving Data for 1channel(8bit header + 24 bit Data ) using 16bit SPI and DMA in circular mode . i am not using AD7768 DRDY pin. I am recieving 1 vaild data after some grab data's (eg:0x00000000 , 0x008325DB) again somewhere vaild data(eg:...
I'm starting project with custom board that is controlled in STM32L031K6T6 MCU.I set up that with cube ide and wrote simple Timer code.Unfortunately, It isn't work. Not only that, Nothing is happend(uart, Hal_Delay, GPIO...)But oddly enough, it is wo...
Hello....I have TIM1 clocking at 1ms. It rolls over at 1000 counts (ie 1 second). Within the pushbutton IRQ I add 50 to the timer register and disable the GPIO IRQ. I would also like to enable a compare IRQ here as well, such that after the counter c...
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...
