I am looking for some guidance how to implement a system that utilize both SDMMC and USB MSC so I can read/write data inside SD card from MCU and external PC.Thank you for your helps
Hello, I am developing a driver for the STM32H743 Ethernet Interface with external LAN8742A PHY on the NUCLEO H743ZI2 board.I am doing stress tests. When transmitting and receiving a large amount of frames simultaneously, sometimes the TI interrupt i...
Hi!I have STM32F373 and I want to send data with USB FS.When I generate a project, I get this struct.PCD_HandleTypeDef hpcd_USB_FS;What should I do to send data with that struct?
I've noticed that when I connect my STM32F3Discovery board, configured as a USB virtual COM port, using only the USER cable, I will get the "USB device not recognized" error on the windows side, and more specifically "Device descriptor failed" in dev...
I'me using STM32F103C8 MCU with Stm32CubeIDE 1.6.1. Project uses CMSIS OS v1 and 3 UARTs enabled global interrupts. UART settings 57600 8 N 1 for all three.Interrupts handled in the callback:uint8_t rxByte[UART_COUNT] = {0}; QueueHandle_t uartQueue...
I get always zeros from my code. Is there something you see immediately.This is what TI tells me to do (I have ADS1115).For example, to write to the configuration register to set the ADS111x to continuous-conversion mode and thenread the conversion r...
We are using the STM32 USB Device Library.This is the USB circuithttps://peter-ftp.co.uk/screenshots/20210511523173514.jpgDoes the STM library implement this, or do I need to detect a drop in VBUS (cable to Controller being disconnected), or is no ac...
Hello All,I am having an issue interfacing an SD card to the STM23H7.I am using the SDMMC1 with 4 bit wide bus. When testing HAL_SD_WriteBlocks , I can write and read from the card successfully at various lengths (different number of blocks). But I...
