My STM32H747 (Portenta H7), with latest CubeHAL H7 drivers, fails on USB streaming, as USB audio from MCU to host (USB Digital Microphone).It enters in USB FS IRQ handler all the time the branch with the "Incomplete ISO OUT". Nothing comes out to PC....
Not just an idea, something to verify:"PDM microphone via USB or Network"Instead of doing the PDM2PCM conversion (inside MCU) - send the PDM bit stream to a host PC at it is. We can do the PDM to PCM conversion, e.g. with Python scripts, on a host PC...
Hi, i'm trying to set up the RTC timer to be able to use the alarm and HAL_RTC_Init always return HAL_TIMEOUT. It seem like RTC_ICSR_INITF never go to 1. uint8_t init_RTC() { /* USER CODE BEGIN RTC_Init 0 */ /* USER CODE END RTC_Init 0 */ ...
I want to use a STM32G4 device in a new project but I was disappointed to find the USB implementation only supported Device mode.What is the hardware (implemented in the MCU) that make it capable of host mode from device mode (OTG supports both)? Wi...
I'm developing a vibration and temperature analysis system.To do this, I have developed a sensor based on an STM32L053C8 chip and a KX122-1037 accelerometer.Looking at the datasheet, this accelerometer can reach a maximum data rate of 25600Hz, which ...
1. stm32F105 + stm32cubemx2. project was created using freertos by stm32cubemx,no peripheral enabled,and config no use gpio as analog.3. mcu can go to stop mode normally before os started4. mcu wakeup for unknown reason when enter stop mode in defaul...
HiI would like to store the call stack when the STM32H7 crashes. I implemented unwind.hThe code works on a bare metal simple est code but not with FreeRTOS is runningAny idea as to why? The code static uint16_t CallStackAddr;CALLSTACK_DATA uint3...
We are using STM32CubeProgrammer and STLINK-V3SET to program our products on our assembly line for mass production. We have a couple of questions 1) Is there a way to program using the command line or some other mechanism to keep a record of the numb...
Hi, I am using STM 32 STLINK-V3. Thereis a problem with following UART receiver function. __HAL_UART_CLEAR_FLAG(&huart5, UART_CLEAR_NEF|UART_CLEAR_OREF); HAL_UART_Receive(&huart5, rx_buffer, ROVER_MSG_LEN, 1000); __HAL_UART_DISABLE_IT(&hua...
Hi all, for a projet I need to create a signal at 500khz, and every 60 µs I want to stop the toggle (or not) I generate the signal with the output compare of tim2 (on stm32L073)then, in TIM2_IRQHandler(void)I try to count the number of call, then st...
