is it possible to put designs on caravel that have direct access to a few gpio pins? i'm a bit confused by the docs, which say no, but I thought some people had gotten this to work?

you mean caravel analog? 11 bare pins. You need to take care of ESD

does that mean there is no such support in caravel (digital)?

afaik, no

You can connect to the analog pad of the digital io, but the bw is limited

ah ok, thank you

@aryap: You can connect to the pad but there is an ESD protection resistor in series between your connection and the pad which is 150 ohms. So if you can tolerate that 150 ohms and the ESD diodes which will limit your voltage range to within the power supply rails (approximately), then it's okay to make the connection on the

analog_io

pins of

amazing, thank you
