Hello, I am using STM32L4S5VIT in LQFP100 package, i want to control a non-muxed PSRAM Memory of 64Mb (ref: IS66WVE4M16EBLL-70BLI) by FMC bus.The problem is that the MCU have just the Muxed Mode as shown below :Can i add a multiplexer to connect betw...
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...
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...

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...
