Can the SPI run at another voltage apart from VDD?

The data sheet isn't specific, apart from one diagram Figure 13 that shows IO's box with an arrow from VDD that then connects to a level shifter to the core domain.Please advise. A real handy feature would be to alternative voltage IO for the SPI's...

When setting up pins to communicate using SPI on a sensortile I changed the Pins so one is the C and one the B GPIO, how would I set this up, I haeve only seen one somewhat related thread that wasn't comparable, thanks!

Why my timer encoder mode oscillates in the same values?

Hi, i'm using my STM32F7 nucleo 144 and i'm learning about timer encoder mode and i follow the example in the datasheet but when i check the CNT register it oscillates in the same values and if i use the A0-A1 pins the encoder works bad, can somebody...

STM32L452RE ADC Bad value on just one of the 9 channels

I have STM32L452RET6P running at 1.8V, 24MHz. I am using nine ADC1 channels and am getting a very low value (about half) on ADC1-1 (PC0).All inputs are set up the same way, with an RC filter (33kOhm/0.1uF). The sampling rate cycle is 12.5 at 10bits, ...

Resolved! SPI interrupt too slow for SPI frequency

I need to confirm my understanding. Say that my STM32H7 SPI is setup as Slave and that it processes the incoming SPI data byte per byte in interruption. It is very likely to happen that the SPI throughput is faster than the SPI interrupt handler dura...
