I have been able to implement individually:SD + FreeRTOS + FATFS + DMAUSB + FreeRTOS + FATFSI want to know how can I make (SD + USB + FreeRTOS + FATFS + DMA) work. Example would be great. Thank you every much.

I cant't figure this out. I had no problems installing and using the driver with a Nucleo board on my desktop. However, the installer keeps failing on my laptop. The installer asks for and I give it admin privileges. I tried to manually update the...
I can't get the STM32L07RZ-Nucleo ADC regular conversion interrupt example to work. I'm using the Keil MDK variant. I upload the program, start the debugger and put uwADCxConvertedValue into watch window #1The doc file says to connect a signal to P...
Hi,I have a nucleo L053r8 and a nucleo f401re boards. I want to use the st-link of the L053 board to load code and debug the f401 board. I removed jumpers from CN2 and connected the pins of CN4 connector of l053 board to the correct pins of the f401r...
I want use to use a stm32L011 nucleo borad without a PC. Once the code is downloaded I want just supply the power of the nucleo board through the USB port with a single USB charger. When I did it, the nucleo board doesn't start the code. If I supply ...
Hi, I'm new in this world of ST. I have relative experience with Arduinos and LoRa, but now I want to do things with more resources. In particular, I am interested in the LoRa module from Murata and I bought the Discovery Kit B-L072Z-LRWAN1.What I as...
I am reviewing the stm32f4xx_hal_spi.c to setup the SPI interface for Master mode DMA receive-only use. I notice the table showing that in this mode the maximum SPI frequency is Fpclk/64. I haven't bench tested this yet but was curious why this is so...
