Hi STM32 Community,I'm using a SoM with the STM32H750, made by Emcraft. My goal is to set up Ethernet using the standard HAL library alongside lwIP. However, I've hit a snag with the MDIO communication to the PHY(a Waveshare LAN8720 board).Based on t...
Hi,I have a requirement to transmit and receive CRC-16 hardware computed checksum via SPI in stm32L151 microcontroller.As per the datasheet, i configured polynomial 0x1021 and enabled CRC.the problem is, CRC register TXCRCR is updating for all instru...
I'm working on a project involving the integration of USB functionality for data transfer and data logging on an STM32F407VG microcontroller. The project's objectives include logging data files on an SD card and allowing users to download these files...

Hello STM Community,I hope everyone is doing well.We are currently using the STM32 USB in our commercial products, focusing on the CDC class. Through our exploration of the documentation, we haven't found a conclusive answer to our specific question....
Hello,I was just porting a F767 design to an H723-Nucleo, and found out that this H7 Nucleo is using its ST-Link's HSI as a clock source to the H723 at 8 MHz. With the usual terrible HSI quality, which showed itself in low quality SPDIF TX and PTP sy...
Hello, I'm working on a STM32F407 LwIP acting as a TCP server with a bare winsock based client on Windows 10.The project is derived from CubeMX V1.27.1 with the tcp_echoserver.c module creating and communicating to the client.After a few transfer of ...
If this is not the right section of the forum to ask this question, I kindly ask you to move it to the correct one. Thank you!I need an ADC with differential input but I only have STM32F407 (which doesn't have it). I was thinking of sending the diffe...
Hello,sometimes the initialization of the SD card fails in function SD_FindSCR.There seems to be a timing problem between SDMMC_ConfigData and SDMMC_CmdSendSCR because send data starts before SDMMC is ready.With an additional wait function for status...
