I am interfacing TFmini S LIDAR with nucleo STM32F103, I am using 2 UARTS, uart1 and uart3 to receive LIDAR data. I am using DMA for that. LIDAR frequency is 1000Hz and data length is 9 bytes. uart 1 and 3 baudrate is set to 256000.
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...
WHY MISO ECHO BACK WHAT MOSI SENT, EVEN THE MISO PIN IS ALREADY DISABLED.
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...
How to write non-reserved option bytes on STM32H750xx MCU?
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...

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...
heap allocation on segmented ram
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...
STM32L - Programming issue -> Internal command error
