I want to make voice recorder with STM32F7 and save voice as .wav in SD card. before this one, i tried to save audio samples as .txt file, but during save them in sd card by FAT, some sample has been lost. therefore i try to another way. Please help ...
I am using an STM32L071CB MCU. It has a Cortex-M0+ core.I noticed that the implementation for `HAL_PWR_EnterSLEEPMode` in the latest version of the HAL uses a NOP instruction to "flush instructions" before WFI. I don't understand how this is guarante...
Hey,I followed the intructions of the Youtube video and put the code in the files like it is described in AN5418 for the STMG474RE. There were no errors after building the code. So I flashed it to the board and tried to run this example.But the STM32...
I am currently developping a system which uses an STM32L496 as a USB host that communicates with up to 6 USB devices through a few hubs. The devices are all CDC or Audio class, and are controlled by the singular STM32L496 on the USB bus, but there is...
I try to use the M4 for ADC. it always report timeout in HAL_ADCEx_Calibration_Start or HAL_ADC_PollForConversion. I use STM32CubeIDE 1.5.1 with STM32Cube FW_H7 V1.8.0. I also try to initialize ADC in M7 and use it M4, get the same error message. If...
Hello Sir.In STM32H747I-DISCO board, LAN8742A IC cannot read properly.Always read only the 0xFFFF value. In the same source, NUCLEO-H745ZI-Q board reads IO of LAN8742A well.In LAN8742.c ®value is always 0xFFFF. if((pObj->IO.GetTick() - tickstart...
My new project use 3 SPI with interrupt method. When the SPI is receivedin HAL_SPI_TxRxCpltCallback(SPI_HandleTypeDef *hspi) this function How to identify which set of SPI has been received ?
I am starting a new project on STM32H7 and would like to start using AzureRTOS.I have a very primitive example on github here : https://github.com/c4chris/H745-Test I thought I could simply replace FreeRTOS with AzureRTOS on both cores, but so far I ...
Hi,I have a problem with HAL_UART_TxCpltCallback not getting called after UART transmission using DMA. I set the DMA in Normal mode. I also turned on the UART global interrupt in CubeMX. Actually the USART1_IRQHandler gets called after I send some st...
Hello,We have purchased the STM32F769I-DISCO KIT as we plan to use STM32F769I in USB audio IN/OUT application.I am trying to make "STM32CubeExpansion_USBAudioStreaming_V1.0.0" example provided by ST working. So far: I have configured the above exampl...
