Problem with two simmilar projects
Greetings everyone!Lately, I have generated two projects for Nucleo-STM32H745ZI EvB.The first one was generated just for the MCU and for the second one I have chosen the EvB as a reference. So now I do have two quite simmilar projects where the first...
Resolved! Can dual circular DMA buffer be implemented on a single RX USART?
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...
STM32H7 Huge program with UART Tx using DMA
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...
Where in Cube IDE are the linker options?
For example how does one put an array or a stack into the CCM RAM?
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...
STM32H755 dual core debugging issue is related to BOOT_CM4 option byte
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...
How do I configure GPIO pin (PE8 )as PWM output to control LED Brightness.
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...
