Is it possible to use the SAI peripheral with the data line only - SD_A or SD_B (without outputting the peripheral clock signal) when using the "free protocol" mode for a single-wire communication purposes?

Dear STM32 MCUs community,I am currently working on a project with the STM32l452RET6 MCU with a goal to use the SAI peripheral for one-directional single wire communication purposes, so only the "data line" (SD_A or SD_B) will be outputted using the ...

STM32F446 MCU LSE Ready Issue

Hello, I used STM32F446 MCU. I'm disconnecting the external RTC crystal. Then I turn the device off and on, but the LSERDY bit does not become zero. What could be the reason for this? Thanks.

Resolved! Weird ADC failure STM32F091, any ideas

We've been building a PCB with four STM32F091s on each PCB and we've built about 50 units by now (over about 3 years). I have now seen three PCBs where the ADC readings are 'bad' on two of the four micros. By 'bad' I mean conversion values are 30% is...

ADC direct channel issue on STM32H7A3

Hello everyone,I'm having some throuble in reading the direct analog input on channel PA0_C.In my design I'm using several analog input. They seems to work properly in general and I have a precision more or less as expected. On channel PA0_C, though,...

Waking from Standby with any GPIO with STM32L4?

I thought of using an STM32 to build a device which responds to infrequent pushbutton presses, but should also conserve battery. My initial instinct was to use an STM32L4 in Standby or Shutdown mode, setting the GPIO as external interrupts which woul...
