STM32 MCUs Products

Using I2S on IT with STM32F407, I observe that the SPI_I2S IT asserting rate is not the audio sampling rate.

The IT asserting rate seems to be totally de-correlated with the rate of reception of a sample from the microphone.Has somebody already used a microphone MEMS I2S ICS-43434 by InvenSense-TDK ?I don't succeed to connect a stereo pair of this microphon...

I am interfacing ADS8688 with stm32f429zi, I have used SPI. I have 2 different setup. first setup with 3 ADC in which all ADC channels gives output near 47000 and Second setup with 8 ADC which channels gives values near 23000. Why it gives half values?

STM32G030F6 I2C2 set to slave mode, it can not work fine.

I am newer in STM32G030 develop.I tried to set STM32G030F6 I2C2 slave mode with PC.Q1.Using "HAL_I2C_Slave_Transmit(); it seems Master (PC) read 8 bytes later and stop. The other data will not read.Q2. If used HAL_I2C_Slave_Transmit_IT(), It only wr...

Can't figure out why RTC wakeup event doesn't work

Hello,I've followed all the steps required to generate and handle a RTC wakeup in the manual, but it still doesn't work. I can't figure out why that doesn't work.The goal of the following code is that, when I click the reset button of my nucleo L152-...

Exact meaning of VIL and VIH and the resulting switching point between HIGH and LOW

We want to realise a cheap measurement of a external voltage over a voltage divider with a STM32F765ZI processor. We calculate VIL with the formula "0,35*VDD-0,04" which is guaranteed by design. On base of this calulated VIL we calculate our voltage ...

Is there an example of implement Mbus slave for serial connection

We have multiple STM32 uC on board and would like to share as many connections for programming the parts.

Is there a way to connect them in parallel with some individual enable to reduce the outward interface of the board. ie maybe connect everything in parallel except for RST line or ??? any suggestions would be appreciated
