Basic Manual for DaFit Fitness Tracker firmware update protocol, works for nearly any nRF52832 tracker from Company DaFit

The minimum size of update file is 0x10000(can be filled with garbage to get to size) and the maximum size is 0x2F000
the update will first get stored onto the external flash at position 0x3D1000 by the stock firmware(not by the bootloader)
the size of the update will get stored at 0x3D0000 on external flash with 4 bytes uint32_t

when bootloader gets activated it will copy the update from external flash to 0x23000 of the nRF52 internal flash.

If you are like me you find yourself cloning a repo, making some proposed changes and then deciding to later contributing back using the GitHub Flow convention. Below is a set of instructions I've developed for myself on how to deal with this scenario and an explanation of why it matters based on jagregory's gist.

To follow GitHub flow you should really have created a fork initially as a public representation of the forked repository and the clone that instead. My understanding is that the typical setup would have your local repository pointing to your fork as origin and the original forked repository as upstream so that you can use these keywords in other git commands.

1. Clone some repo (you've probably already done this step).

   git clone git@github...some-repo.git

rbnpi

This program runs on Sonic Pi midi version. It works on SP 2.12-midi-alpha6 released recently to patreon subscribers of Sam Aaron see https://patreon.com/samaaron It also requires the program TouchOSC which is available for iPad or iPhone users at a very modest price. The TouchOSC file required to run this program is contained in the file index.xml To produce the TouchOSC file, download the raw file index.xml, right click it and select the Compress function. Rename the resulting file SPlissajous.touchosc and say Yes when it asks if you want to change the file extension. Open the file using the TouchOSC editor and download it to your iPad or other compatible device using the sync function. The layout is designed to fit on an iPhone or iPad. The SPlissajousTouchOSC.rb file should be downloaded and opened or pasted into a blank Sonic Pi buffer.

Remote GPIO

GPIO Zero allows you to create objects representing GPIO devices. As well as running it on a Raspberry Pi, you can also install GPIO Zero on a PC and create objects referencing GPIO pins on a Pi over the network.

To do this, you'll need to do a few things to get set up:

1. Enable Remote GPIO on the Pi in the Raspberry Pi Configuration Tool.

2. Run the pigpio daemon on the Pi:
