@inverseeffect Unit testing on hardware is a little more difficult that pure software because timings can be variable and you need to have real hardware connected. It certainly is possible to create small units of code and have them run and check their results, it's no different to running your full code, just split into smaller chunks and with more checks.

Solved: just needed to increase the timeout to 2 seconds before setting machine.pin_deepsleep_wakeup(['P3'],machine.WAKEUP_ALL_LOW, True) and then going into deepsleep

Thank you. Everything works now. I hope that pymakr will be fixed as well.

@jmarcelino Ok that makes sense. ADC threshold sounds great, as does a simple GPIO-based pulse counter in case you're looking for ideas :)

Hi, the new WiPy available for purchase on the webshop does have the increased memory: 4MB RAM, 8MB flash and fully working DeepSleep. Best wishes Fred
