tt-392 / tt-time

the beginning of a bigger pinetime os project.

TT-time

This is the start of a project for the PineTime. Some day it might be a nice usable smartwatch OS, but right now, it is starting to look more and more like a fancy tech demo.

Compiling

(this part needs some work)
Extract the nRF5 SDK (https://www.nordicsemi.com/Software-and-tools/Software/nRF5-SDK/Download#infotabs) somewhere on your computer In the Makefile, replace ../sdk with the path to where you extracted the SDK.

Uploading

To upload this code using the instructions on the pine64 wiki:
https://wiki.pine64.org/index.php/Reprogramming_the_PineTime The .hex file is located in the _build directory
I personally use a J-link programmer with the nrfjprog commantline tool.
To upload using this tool, use the following commands:

cd _build
nrfjprog -f NRF52 --program nrf52832_xxaa.hex --sectorerase
nrfjprog -f NRF52 --reset
