Hi,I was wondering on how to access USB DFU mode on STM23L412.As it seems, I'll have to power up the board to be able to reach it.Just resetting does not seem to be enough...Is this so, or am I doing something wrong?I tie Boot0 to VDD and pull nRESET...
I just learn try to make RAW API LWIP http server. I have done with simple html. I just used MX_LWIP_Process(); Now I want to handle long url like 192.168.1.10/menu/config/hardware/... I have made many sub folders in fs folder, but it only work when ...
Hi.HAL_I2S_Transmit_DMA() and HAL_I2S_Receive_DMA doesn:'t work simultaneously. As a result, programmer cannot use I2S TX and RX together in the STMH7 Duplex I2S.STM32H743CubeIDE 1.2.1STM32Cube FW_H7 v1.6.0Attached screenshot points where the API ret...
I encountered this problem when I attempted to send a one byte command using HAL_SPI_Transmit(..), and then trying to read 2 byte response from Miso, using HAL_SPI_Receive(..)My test code is plain as follows, no intterupts, nothing connected to SPI p...
Hi there,I'm designing a PCB which will feed audio at 48KHz / 96KHz / 192KHz to a DAC over I2S (TI PCM5242).I'd quite like the option to have USB - in an ideal world, USB Audio, but at the very least a COM port (USB device).For the DAC, I'd need an H...
Hi all,I had an occasional issue on my project (STM32H743) which uses SD Cards (FatFs). In general the writing to multiple files was working perfectly, however after a while, writing to the SD card (when frequently interrupted by SPI-Receive-Interrup...
Hi,Greetings!Wondering whether the following logic works:Configure TIM7 for a sampling rate of 48khz. TIM7 triggers DMA to fetch audio samples at this rate, dumps it into the DAC buffer.Is this the right path ?If so, how to go about with the dual cha...
Hi,In order to compile FreeRTOS in C++, I did a makefile that compile FreeRTOS in C (to avoid void* issue not recognized by C++), and the other files with C++ including stm32h7xx_it.c on cpu Cortex-M7.Whatever the options of compilation I am using (...
Hello,I'm just developing upgrade path of my custom STM32F767 device. I can enter stock bootloader with boot0 pin+reset as well from software jump. It works fine, programs flash and option bytes. The problem arises when I'm trying to program protecte...
Hi!I have been searching for days trying to find an answer to this question. Lots of people have similar questions but none of the answers have worked for me. I am trying to get my STM32L071xx to jump to bootloader from application code. I need this ...
