I had success when using the ULPI interface on a STM32H7A3 (on the nucleo board) using an external ULPI transceiver board https://www.waveshare.com/usb3300-usb-hs-board.htmbut when porting over to the STM32H7B0, I am not having much success. I believ...
Hello, I happened to have to make an MCU board for a military application. Generally I always use STM32 MCU with which I am very comfortable.But for this specific application I tried to search if there were any MCUs specifically designed for mil...
Hello,I'm on a STM32H743 (nucleo-H743ZI2), and I got LWIP (no OS) to "work", as in it receives ip packets and reads them. The problem is with allocating on the heap. I didn't use the libc_malloc option, the heap pointer is at 0x30044000 and is 1600 b...
I am trying to implement a simple soundcard from using STM32F407G-DISC1 board.It utilizes STM32F407. I am using CubeIDE version 1.10.1I configured the USB to be Full-speed Device Only. And I configured the middleware as Audio class.I set the the heap...
I am trying to implement a UART Rx using a typicalstart-byte, length, payloadpattern.I spin read on 1 character until it is my start byte. Then I read 2 bytes, shift them into a 16 bit length and read the remainder of the payload.The trouble is, the...
I am trying to stream audio from my PC to my STM32F411CEU (custom development board) with USB. Using STM32CubeMX I configured my MCU as audio device class. When I plug STM32, the PC reckognizes MCU as STM32 Audio Device but there is an error, the dev...
HiIn the various filex with SDMMC examples the icache and dcache are enabled so when porting I did the same.I noticed when attempting to use DMA SPI it was not working until I disabled these. For the SD I then have to disable cache and cache manageme...
I'm designing a board with STM32F411RE which needs to support DFU for firmware upgrade.Looking at AN2606 on bootloaders, I will need to use BOOT0 = 1 and BOOT1 = 0 to start in DFU mode.However, looking at the schematic for the Nucleo f411RE, it looks...
