Hi everyoneI was wondering if it would be possible to implement a DMA setup without interrupts that maintains two circular buffers for the same USART? I would like to save both the SR and DR register values in two separate circular buffers every time...
Hey guys!This probably came up 5000 times, however I did try to look for a solution before I ask this one. Couldn't find one.I am having issues transmitting data via uart with DMA.Problem:The problems I am having is that the RxBuffer is not receiving...
For example how does one put an array or a stack into the CCM RAM?
I am using HAL_UART_ErrorCallback() function to capture any error.When I reset the the board by cutting the power off everything works fine. But if I reset it with reset button or software reset one of the uart freezes and I don't see any error. I ha...
I make a code that is just send SPI data, and the MISO should not return anything. Here is my code:int main(void){ char user_data[] = "Hello World!"; GPIO_ButtonInit(); SPI2_GPIOInits(); SPI2_Inits(); SPI_SSOEConfig(SPI2,ENABLE); while(1) { whil...
Hello!The STM32H750xx data sheet states that the MCU has 2KB of space in flash memory for "option bytes." However, the programming reference describes on page 176 that "Table 21 lists all the user option bytes managed through the embedded Flash memor...
Hi all, I'm editing this post because the forum doesn't allow me to delete it, and it might help someone else..I was having an issue where simply generating a default NUCLEO-H755ZI-Q project from the current latest CubeMX for Cube IDE and following t...
I am a newbie and trying to make my hands dirty in STM32l476 Discovery board.I am trying to control the brightness of an LED which is connected onboard at GPIO PIN PE8. The TIMER on this pin is TIM1 CH1N. What I have tried is till now is below. I wou...
The ram on the STM32H7 is segmented into non-contiguous sections. How would one be able to dynamically allocate memory in different sections of RAM? eg: put large objects in AXI-SRAM and small object that need fast access on DTCM.I'm wondering if thi...
