Hi!I wrote a program to write a .bmp file to SD card using FATFS. I am using STM32CubeIDE and its generated code. I converted my .bmp file to a byte array online and then copied the array to my program.If i write the whole data at once, everything i...

I made a UART project in STM32CubeIDE. Cube generated the necessary UART initialisation code and created UART_INIT() function (or something like that) in main(). The project worked.Then I decided to add DMA. I regenerated the code and couldn't find D...

Hi!I would like to make a wav. player using STM32 microcontroller. My first step was to generate a sine wave using STM32F103C8T6, SPI interface and external DAC MCP4921. However, it's not working.I attach the schematic of my device.I wrote 2 versions...

Before explicitly calling HAL_UART_MspInit() in main() I actually made a breakpoint in it to find out if the function is called or not. And the program didn't stop there. That's why I assumed that this function is not called automatically. Maybe I ju...

I tested a timer previously. In the first version of the program it generates an interrupt every second. It worked. So in the second version math should be correct.

Thank you for your answer! I will try out your suggestions a bit later.The reason why I enable and disable SPI this way is because my external DAC needs to receive CS signal (low->high) after each 16-bit data transfer. This is quite inconvenient. Sin...
