I have an application running on an ST32F446 using code generated by STM32CubeMX. I use SPI1 in slave mode to receive commands, and have FATFS operating with USB HOST to connect to a USB FLASH drive. I can send commands via the SPI interface to open ...
This is not a question, more like a statement and proposal to update datasheet.In these two datasheet:DS9716, STM32F401xB STM32F401xC, DS9716 Rev 11, page 105/139DS10314, STM32F411xC STM32F411xE, DocID026289 Rev 7, page 114/149It are specified sample...
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...
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...
