Did anyone tested audio playback on STM32746G-Discovery board, for any STM32F7 SDK version?

Hi ST community,Did anyone tested audio playback on STM32746G-Discovery board? May be one of the following use cases:(1) Audio_playback_and_record which is available in Applications/Audio folder OR(2) any simple use case just to play the audio PCM da...

Audio_playback_and_record on STM32Cube_FW_F7_V1.15.0 for STM32746G-Discovery not working

Hi All,I am trying to run Audio playback and record application present in the path:STM32Cube_FW_F7_V1.15.0/Projects/STM32746G-Discovery/Applications/Audio/Audio_playback_and_record/SW4STM32/STM32F7-DISCOBut it hangs inside "FRESULT AUDIO_StoragePars...

ethernet with dp83848 on RMII mode

I changed ethernet transceiver chip .My ethernetif.c file works with lan8742 but I have to use dp83848 on my project.I've compare datasheets of two chips and I've edited lan8742.c-h files according to dp83848's datasheet.However it's not work...

Uploading DFU bootloader to external STM32F072 using STM32F030 NUCLEO-64 board

Most of the websites including ST say that you need the USB pins of the new MCU to write the bootloader using Dfuse software. Is there any way to write the DFU bootloader to a new STM32F0 MCU using the SWD pins on the STM32F030 NUCLEO board? I have t...

What is the easiest way to update the user firmware (microcontroller application code) on a Nucleo board?

I'm working with a Nucleo F429ZI, and I want to be able to make firmware updates to the board in the future, preferably through the board's USB port (not the ST-Link debugger USB, as this will be removed for my application.) I was wondering what the ...

Confusion with interrupts and handlers in HAL

I'm using stm32f103c6, i'm confused as to how should i handle the interrups, what i need is to count pulses from an external source, it has to be accurate so the best way is to do it with timers right? So i've configured the cnt_en from timer2 to act...

STM32L0 IrDA pulse issue

Trying to implement an IrDa and comparing to a tv remote the pulse width is very different, ours is around 18.4uS where the tv remote is 540uS for a short bit. I cannot seem to adjust this exept for reducing the baud rate.What clock speed should be s...
