Getting code on the watch
|
||||
-------------------------
|
||||
The watch library in this repository is very work-in-progress, but it should allow you to get started. To create a new project, copy the “Sensor Watch Starter Project” and write your code in the app.c file.

The watch library in this repository is very work-in-progress, but it should allow you to get started. To create a new project, copy the “starter-project” folder in the apps folder, and write your code in the app.c file.
|
||||
|
||||
You will need to install [the GNU Arm Embedded Toolchain](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads/) to build projects for the watch. The watch library has been tested with the `9-2019-q4-major` version and the `10.3-2021.07` versions.
