How to produce audio on STM32H745i-disco with the WM8994 audio codec?

I am having issues producing sound from the audio codec. I have tried the examples provided by ST but have not been able to get them to run. Is there a step by step guide to follow for more instructions?

HCI_HARDWARE_ERROR_EVENT occurr only when writeing/eraesing flash

Hi. I received a board in production state with FUS 1.1.1 BLE STAK 1.8.0 This board has a function to log data into flash peridically. Most of our board working well but this board fail to log data after few minutes from power on and BLE stack looks ...

Project for STM32F746 disco with the protocol 61850 Ethernet communication, work with DSP library, working in real-time.

I am trying to make a frequency relay with the STM32F7 disco, for a simulated power electrical systems in real time (OPAL RT); I need to establish a communication between the real time simulator and the STM32F746 dico, through one of the protocols it...

Write JPEG data from ov5640 to SD-Card

HiI am doing a project using STM32L496G-Discovery and ov5640 sensor,what I am triying to do is capture data with a resolution of 320x240 and JPEG format and save it to the sd cardhowever when i open the file created I don't see anything.

I am working with stm32F100 and I want to calculate the time in hours when some GPIO is on

STM32G431KB: I try to make a PWM signal out of my TIM1 channel. I followed this tutorial: https://controllerstech.com/pwm-in-stm32/ My PWM signal goes from 1V to 4.3V and not from 0 to 3.3V. How is this possible?

UART mixed flow control

Hello all,I have a device connected to a stm32l496rg on a custom via uart.At system startup, the remote uart may or may not have hardware flow control enabled, so what I want to do is configure the MCU UART for no hardware flow control and put the RT...

Changing timer frequency by writing the AutoReload Register every 10 microseconds with DMA on a STM32H743

Basically, the frequency change already works. My problem is that the new frequency, which is specified by DMA, only takes effect after the ARR has been reached.I tried to solve the problem by disabling the auto-reload (ARR) preload.unfortunately in ...

STM32L4 STOP2Mode

I'm using STM32L476VG and STM32Cube FW_L4 V1.17.1 version HAL Function.I thought STOP2Mode and RESUME work fine.However, when I took the current consumption waveform, it is the same as STOP1Mode.Why is this happening?void Sleep(void) { MX_UART4...
