STM32 MCUs Products

How can I use audio on STM32F7508-DK board ? There is a WM8994 connected to SAI2, but I couldn't find any example of audio using SAI, neither audio example for this board. And the driver for the WM8994 is not provided.

I watched many examples on other boards, but they are always using I2S so I couldn't transposate to my case (SAI).For now, I just would like to connect inputs (Jack IN1 or mems microphone IN2) to the output to understand how it works (maybe first via...

STM429I-EVAL1 Joystick Interrupt by ISR

Hello,I am using a STM429I-EVAL1 board. With this I try to trigger an interrupt by pressing on the joystick, which is on the board. The interrupt is executed correctly a few times, but then it aborts. You can't tell when, it can abort after the 10 ti...

[ NUCLEO-L552ZE-Q ] Why "EXTI Line 14 interrupt " not "EXTI line 13 interrupt"?

I tried this tutorial"https://www.stmcu.com.cn/ecosystem/chip/chipfamily-STM32L5-4", it was not in English. bu the illustration is clear, I tried it in STM32CubeIDE version 1.4.0 on Ubuntu 20.04.1 LTS. When I went to the last step - Setting NVIC_S an...

Keeping PA15 low during the init

Hi community,I'm using STM32F303RE, in that I'm using PA15 as a GPIO which is connected to a Relay, but I recently found out that the PA15 is a JTDI pin which is being pulled up internally, so whenever the STM32 resets, it gets high and after GPIO_in...

Reboot necessary after OTP write?

I am using the STM32L432KCU for a project. I intend to use the OTP area for writing persistent device information (serial number, encryption keys, etc).Is a reboot necessary after writing to the OTP area?Can the OTP region be written to 32 bits at a ...

some question about DALI Slave in STM32F

DALI_RX port and DALI_TX port have been initiated twice in" void DALI_Init(TDLightControlCallback LightControlFunction) " and "init_DALI(OUT_DALI_PORT, OUT_DALI_PIN, INVERT_OUT_DALI, IN_DALI_PORT, IN_DALI_PIN, INVERT_IN_DALI, DALI_Interrupt, DALI_Err...

USART3，USART4 how to use

DearI use the STM32H7B3I-DK this board,and I read the manual.The instruction says I can use CN11 digital pin name D0 and D1,but D1 is (USART4_TX)​,D0 is (USART3_RX).Then how do I use the USART3, because do not find USART3_TX​
