Crickit hat for RPi showing overvolt from phone powerpack, o

Hi, I'm powering a Crickit Pi Hat from one of those cellphone backup battery packs. I'm getting an overvolt light on the cricket (the triangle next to the slightly worried looking smilie face), but everything seems to be working okay. How bad is this? Also, I can't find a way to query the Crickit or...

I've taken at look at the compiled code in gdb and objdump, and it looks reasonable and seems organized similarly to the shipped firmware which I dumped from one of the unmodifi...

Re: Query stored data on adafruit.io by time

Thanks for the reply Adam!

Ok, this will work I think. For now I don't actually need this, I can do some querying locally. I will certainly get this implemented down the road and will revisit this forum.

Cheers,

Corey

Re: Query stored data on adafruit.io by time

Hi cweiss! The API endpoint you're looking for is called "Get Feed Data" in our documentation. The "Activity" records are things like, "you created a feed" or "you removed a block from a dashboard". Not particularly interesting in terms of collected data. I ha...

Re: More on interrupts for Circuitpython

It is actually not hard to use interrupts when CircuitPython is running. What is hard is to connect them to the Python code. Things like running interrupt handlers written in Python are not likely to happen in CircuitPython in the forseeable future if ever. However using precode coded interrupt hand...
