I'm working on a project that requires USB_OTG_FS and USB_DEVICE as MSC; I've managed to hook up the SD card to the USB_DEVICE layer and the HAL_SD_ReadBlocks works fine and I can even play back music from the SD Card via the MSC interface. However t...
HelloI'd like to get a STM32 board that has support for HS usb transfer, but i'm not sure how to understand if a board supports it or not, how can i know? Is it enough for the STM32 chip to support it and to have a usb port on the board?thanks
Hi. I have STM32F769i-disco board and i want to execute DFSDM audiorecord example in my board.I have some trouble when executing the DFSDM_audiorecord examples which exists in STM32F769i-eval Board. But i compile it but it doesn't playback..what ...
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 ?
