I have problem with my spi. Its not give me a constant answer with the same code.

Hello, i try to program my dwm1000. I am new on that. At the first step i send 0x00 to take the ID verification (0xDECA1000) but its not constant at the same value. Some times is 0xDECA1000 with the same code. Some times i take 0xDC8A0330 or somethin...

Hi! Does anyone already developed a uart bootloader for STM32G081? Is there any example? Thanks

Hi Everyone, Weare working on a project where using SPI3 with DMA to communicate with flash. The problem we are facing is when copying a file from our module to PC, (file size is around 130 MB), it takes almost 14 minutes to complete the transfer.

Is there anyway we can decrease this time. We are using void DMA2_Channel2_IRQHandler(void) and void DMA2_Channel1_IRQHandler(void). Both RX and Tx callbacks are not firing and really not able to debug this issue. Looking forward to a solution. ...
