Hi! I'm in a conundrum, and am wondering if there are hacks around this. I'd like to use CAN on a a G4. And give it updatable firmware by USB. My options appear to be this:#1: Share a CAN Rx line with Boot 0 pin.#2 Share CAN Rx line with USP_DN.Are e...
Hello,I am trying to restart a STM32L072 into DFU bootloader mode (using STM32 LoRa Discovery kit) .The bootloader is working and I can use it to flash my firmware using a jumper between BOOT0 and VCC.Now I would like to enter bootloader from source....
HAL_ETH_ReadData() reported bufflength 60 bytes (damrxdesc-> DESC0.FL shows 64 bytes. looking at the code, bufflength is derived from DESC0.FL - 4. ). However wireshark shows the incoming frame is TCP ACK with no data. So it should be 54 bytes, and ...
I am trying to run a USB HS example with external PHY on NUCLEO-F756ZG. As I count find example I have gone ahead and created code from scratch. I am using USB3300 external PHY. I have made the proper connection except for RST and +5V to the module b...
I've seen many topics similar to my problem and went through their solutions but they didn't work for me so I'm asking here with details related to my problem. I've made a PCB and implemented USB 2 FS on it using STM32F407 PHY in device mode. here is...
In stm32h743, in SPI, I have a slave device with interrupts enabled. In particular, I'm enabling all the error interrupts (UDR, OVR, CRCERR, FRE, MODF), and the RXP, TXP and EOTIE interrupts, in that order.If I enable EOTIE the first of all of them, ...
Hello ST Community, I am trying to play audio file on STM32G431RBT6, but I am not able to successfully play the audio. I shall be thankful if you can provide any suggestions/ feedback to help me debug the cause of noise in my output. Also I would lik...
Where can I find a complete compilation of the LL Api, especially what USART handling is concerned?I'm trying to implement (with FreeRTOS underlying) a ring buffer driven I/O system to read from and write to UARTs.Do I understand it right? There is o...
I want to configure a USB device using STM32F746.I want to select the USBH MSC Host and Device as needed (without rebooting..).In CubeMX, only "Host Only" or "Device Only" can be selected.When selecting DualRole in CubeMX, a library is not created.I ...
