I am not sure how to read continuous data from an external ADC. The ADC has an SPI interface and a data ready pin.Every time the data is ready, the data ready pin goes low and the data can be read. My goal is to read out the data via the DMA every ti...
Hi every one ..I designed custom board for stm32h745xit6 .My TouchGFX working fine with internal flash .The core board has mt25ql256a and connected as under PB2 CLKPG6 NCSPF8 D0PF9 D1PF7 D2PF6 D3I generated STLDR as explained in ST videos tutorial.my...
I've setup my STM32L475 non-RTOS as a USB HID Host to interface with a barcode scanner. All works well if I call sdf MX_USB_HOST_Process in my main application loop with no delays. However, if MX_USB_HOST_Process is not called fast enough, characte...
Hello, I want to take data from ADC input and store them on the internal flash memory of my STM32f769i-discovery board. Can you help me about the use of flash memory? Thank you.
Hello,we are trying to flash the external NOR flash at address 0x90000000 with Openocd 2-times and get an error at the second flash try: Open On-Chip Debugger > program /home/xyz/kr.elf [stm32h750xbh6.cpu0] halted due to debug-request, current mode: ...
I am having trouble with getting FatFS to work with SDMMC. When I try to do f_mount, I keep getting an FR_NOT_READY error. It seems to be coming from when initializing the SD card in sd_diskio.c. The tutorials I have found online seem to have the BSP...
- STM32G0B0 USART1 receiving RS485 data via interrupt driven data collection. Our micro is attached to a RS485 interface(38400, 8,N,1) receiving BACnet data. The data taken on the 485 bus is different from what we receive in the USART buffers. We h...
Looking to add self test to a project using both STM32L4 and STM32H7While going through the versions of x-cube-classb, it appears versions 2.2.0 must be used for STM32L4 and version 2.3.0 and further for STM32H7.Is there a way to use same version of ...

Below i have attached a code which enables the PLL freq of 72MHz using HSI of 16MHz. The issue is if I give a Timer pre-scaler of 36000-1 (I am using timer2, which in case of STM32F401RE is on APB1 bus so using a pre-scaler of 2 for APB1 which makes ...
