EEVblog #1144 - Padauk Programmer Reverse Engineering
Bug191:
Hi I am new to Padauk and am currently working with pfs154 for my final project in uni.
I need some help with going to deep sleep and waking up. Currently I am trying to get IC to go to deep sleep and wake up on interrupt on pin PA0. After wakeup I set pin PA3 to HIGH to verify that IC is not still in sleep. When I do this it successfully goes to sleep (verified with current draw of only a few uA) but after I bring rising edge to pin PA0 for wakeup it doesnt do anything for about few seconds and then if gives me square wave on pin PA3 instead of just HIGH. After that it shuts down again going to few uA of current draw. I even added capacitor to VDD (5V) to make sure there is enough current for fast wakeup.
I attached my code below.
Please help

Not exactly sure about your specific issue. Have you looked this example?

I recall I rather had issue not to wake up the device due to noise on the pins.

How can we restart the process of getting support for more devices? Is anyone with experience in adding support for additional devices still active?

Are there any notable new devices that can actually be bought publically? e.g. at LCSC?

I did something on the Padauks again:

Apologies if it is not terribly useful. It's one of those things that had to be done, because they were possible.
