I've worked out how to disable in the MEMs microphone I just want to use the blue 3.5mm input to receive/record the incoming audio. Thanks.

SD card not working on STM32F746G-DISC0, error "R/W Error" found when "disk_write()" called?

I have been trying to implement SD card function using SDMMC1 onto the STM32F746G-DISC0 dev board in my custom code which uses FreeRTOS and the TouchGFX. These later functions are working fine, however after mounting the SD Card, any other FatFS func...

The first SPI message is weird in SPI slave using DMA

This is my code in the SPI slave: #define SPI_PACKET_LEN 8 static uint8_t spiRxBuf[SPI_PACKET_LEN]; static uint8_t spiTxBuf[SPI_PACKET_LEN]; void task() { // spiTxBuf has all zeros, but the master sees "00 00 00 00 FF FF FF FF" HAL_SPI_Tra...

Resolved! How fast is ADC able to work with USB?

Hello, I am trying to send ADC data (12 bit) to pc with USB as fast as possible. Now I am using STM32F405 and configured ADC like picture below. Those data of ADC is transfered to the pc by interrupt of DMA which is cirucular mode. And the data trans...

Resolved! AzureRTOS + HTTP WebServer and MULTIPART transfer

Hi All,I've succesfully implemented an HTTP WebServer into our application running AzureRTOS on a STM32F429.I'm now moving to data transfer over HTTP, in order to have a Web page (entry point) for transfering a binary file (encrypted) to remote updat...
