Helder AIO Battery Monitor

[GB3]

Hey guys!

I was just wondering if anyone has completed a battery monitor using the extra pins on Helder's AIO board. I did a search and I couldn't find anything, but I probably missed it. I'm probably going to be using the banggood power supply. I'd like to see what other people have completed

Yes. I have with on screen display and low battery video and shutdown. write up coming soon hopefully.

I am definitely looking forward to that write up.

Wow HoolyHoo, thanks! I'll be on the lookout for your writeup!

Yes!!! Looking forward to that write up!

I'm working on it. Tested it today with Helder's latest board and a Powerboost 1000C but should work just as well with the Banggood power supply. After playing and tweaking the code seems like it's working like a charm. Sorry for the crappy video but here is a sample with me connecting and disconnecting the battery.

Very cool.

i would really love to get that piece of script/ guidance to make htis

To properly use the new code you're going to need a USBasp so if you don't have one pick one up.

Yes, sorry, just been really busy lately but I will make the guide as soon as I get a chance. On the software side it will involve flashing Helder's AIO with a new hex file and installing my python script along with some modules. The easiest way to flash the board is with a USBasp programmer as Helder suggested. On the hardware side for the monitor all that is needed is one resistor and a DPDT switch which you may be using already on your build. The GB original switch will work also if using the Powerboost 1000C.

When finished, the script should display on screen battery monitoring with a low battery warning video and critical battery level video along with an automated shutdown that would cancel if you plugged in the zero to power. Also adding an option to install a extra button that will be monitored that when pressed and held, will initialize a graceful shutdown at any time so you don't have to go through emulation station menu to shutdown. A good placement is same place Kite placed his mode button. That button is optional however and not needed if you don't want it.

Once I do the write up, I welcome all testers for feedback as my testing is currently limited to an outside the case Helder board setup but the good news it works very well.
