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​

NUCLEO H745ZI can't use DMA for DAC like shown in examples online with M7, only M4

SOLUTIONBuffer was being put into DTCM by cube. Ensure it doesn't do that, and you should be set.I want to start by saying that it works on the M4, but not on the M7 and I don't know why. The M7 on pretty much all the peripheral configurations I've s...

"STM32" vs "STM32 Arduino" - I2C difference

Hi, I am trying to debug my code with logic analyzer and see why my code works on "STM32 Arduino", but does not work on "STM32". Viewing at logic analyzer I see that "STM32 Arduino" much more consistent.Why could the message be different "0xD1 0x00" ...
