Hello.I have a project with Azure, and now I want to connect an external USB memory. Does anyone have a tutorial on how to configure the project to be able to read and write files from the external USB memory?I have only found the following documenta...
STM32H743We have 4 SPI busses running at 12.5MHz but the SPI clocks are sequentially. SPI 1 and 2 are using DMA Channel 1 while SPI 3 and 4 are using DMA Channel 2. We would like them to run in parallel.Can they run in parallel.The code uses HAL_SPI_...
Hello everyone, I have a complex problem which I would like help from the memory experts and instruction optimization, if possible. I am trying to receive data using CDC_Receive_FS() call back, and, concurrently, process the data using an ISR which i...
hello,I am using Stm32f407 with an IM69D120 mic. I have couple of questions regarding the interface and configuration of the mic.1) Is it possible to configure the audio codec with a 4 kHz sampling frequency and a 16-bit resolution?2) Which interface...
Dear experts,I'm reading RMs for STM32 models with dual flash banks (F4, H7...) and don't quite understand how to use bank switching.Take the firmware update scenario when old firmware is in bank1 and new is programmed to bank2. So it programs some o...

I recently posted this content in ST's comunity and I can't figure out the problem yet. I updated all the drivers, such as GitHub STM32H747I-DISCO BSP, OTM8009A LCD and NT35510 LCD. Also, I included all the path to nt35510, files nt35510.c and n...
I am trying to get the STM32U575 to wake from STOP3 mode using the NUCLEO-U575ZI-Q dev board. I followed the example to enable the wakeup pin, clear any pending wakeup flag, and then go to sleep. I have this configured to pin PC13 which is the user p...
Hi,I am trying to use the async transfers with usarts, but it fails to enable the UART (using uart_rx_enable), due to no DMA configured for the usart.I have not been able to modify the device tree for DMA, but so far unsuccessful.On the dma2 node, I ...
