Re: ESP32-S2 with 1.8 V IO

Hi thanks,

I knew about that feature to allow operation with 1.8 V flash IC. But what if I want the other pins, not the flash ones, to operate at 1.8 ? Is there any way to do so?

Cheers!

ESP32-S2 with 1.8 V IO

Hi,

I'm considering a design where it would be nice to have the GPIO working at 1.8 V on the ESP32-S2, is it possible? How? This isn't by far my first design with the ESP32 but it's something I never fully understood.

Thanks a lot,
Luís Rosado

Running code from different flash partitions

Hi all! I'm trying to understand if something like the following is possible to implement. - I would like to have a small partition to store data like the device serial number, communication encryption keys, and other secret data. Think 1 kByte would be enough, encryption is required. What type of p...

ESP32 parallel bus readout

Hi everybody! I'm trying to tie the ESP32 to a very specific peripheral. This peripheral outputs a 4 bit data word clocked at 25 MHz on the two clock edges. I'm trying to crack a way to retrieve such high data stream on the ESP, preferentially using DMA. Any ideas on how to do this without additiona...
