Hi Jorgen,

Sorry I changed the SPI CAL layer slightly to get the S3 working better with IDF v5.1.

There's an example here if that helps. I'll post it to the component wiki page too.

Lol Steve beat me to it

Hi Stefan,

Thanks for that, hopefully resolved now.

Hello,

The Flowcode web developer now has a component to allow you to do serial communications from inside the web page. Hopefully that's what you're after but if not then let us know.
