STM32F4 HAL USB CDC - Occasional re-enumeration when I2C is also enabled

This is a super super weird one.My device (STM32F401RC) uses the latest HAL libs vs STM32CubeIDE. USB is configured as device-only, CDC.It works *perfectly* until i also enable one of the I2C peripherals (HAL, config'ed as I2C slave) and send/recv I2...

What woul be the best way to read ADC in an RTOS?

I'd like to get ADC readings, implemented with DMA while running in an RTOS.The problem is that the ADC with DMA interrupts the RTOS... don't know what could be the cause maybe interrupts conflicting?

[BUG] - HAL_I2SEx_TxRxCpltCallback never fire in DMA circular mode

I was usig stm32f4 hal version 1.11 and in that version there was this code:void I2S_DMATxCplt(DMA_HandleTypeDef *hdma) { I2S_HandleTypeDef* hi2s = (I2S_HandleTypeDef*)((DMA_HandleTypeDef*)hdma)->Parent; if((hdma->Instance->CR & DMA_SxCR_CIRC)...

STM32H745 and RTOS timers

I'm using AzureRTOS to develop on the STM32H745. I've started with the CM7 core and I've generated some basic code using CubeMX. I've selected TIM6 as a time base for HAL, since AzureRTOS will take over systick for it's uses.I've made a couple thre...

Resolved! HAL_I2S_Receive gives 0s although codec transmits data

Hello!For a week i've been trying to configure my stm32f302cbt6 and the tlv320aic3254 codec to trasmit data to the mcu through i2s_ext_sd but HAL_I2S_Receive returns 0s to the buffer although i see data coming out of the codec. I have configured i2s2...

Flash Erase on STM32G4 doesn't work as intended

I'm running a STM32G473CB with 128kb flash, and I'm getting some issues erasing pages in bank2 of the flash. Using HAL_FLASHEx_Erase the way it's meant to be used, like in the following code that's supposed to erase pages 30 and 31 of bank2, I don't ...

mbedTLS_ssl_handshake failed error while connecting to AWS IoT Cloud using LWIP

Hello,I am trying to connect the STM32F429ZI Nucleo development board to the AWS IoT Cloud using MQTT Protocol, with FreeRTOS and mbedTLS middleware v2.16.2 enabled.I am using DHCP and am able to get the IP. Without security, the code works fine with...

Resolved! STM32L462 - Invoking UART bootloader from user program ( without using Boot) pin.

I working on a STM32L462 project, which needs to invoke the bootloader from the user program. I don't have access to the Boot0 pin. I came across two methods of doing the same but not sure which one should i employ for clean transition.Method 1: - Se...
