STM32F072RB interfacing with nrf24l01

I am using STM32F072RB and I have interfaced it with NRF24L01 module.I have refer the library files attached below for nrf24l01 module.I am trying to send string "Hello World" from one module to another. .Transmission found ok, but at receiving side ...

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. ...

Hi, all , i tried to connect a blue pill board to my pc via usb but i cant seem to get the connection to stick , i dont want to use stm cube and want to do it with raw code, is there anything in the datasheet that yo ucould highlight for clarity?

Unable to establish communication between STM32L4R5ZI and S25FL128L(NOR Flash) via Quad SPI.

i have generated the code from STM32CubeMX for OctoSPI, but not able to establish communication with NOR Flash.It get stuck at following line "if (HAL_OSPIM_Config(&hospi1, &OSPIM_Cfg_Struct, HAL_OSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK)" and goes to ha...
