This repository contains instructions and source code to build Dialog drivers using only the Fuchsia SDK.

Prepare yuor environment

  1. Run the bootstrap script that downloads the appropriate Bazel binary:
scripts/bootstrap.sh
  1. To verify that you can use the ffx tool in your environment, run the following command:
tools/ffx sdk version

This command prints output similar to the following:

andresoportus@andresoportus:~/src/dialog$ tools/ffx sdk version

  1. To load the driver components on Qemu, first start the Qemu as specified in https://fuchsia.dev/fuchsia-src/get-started/sdk/get-started-with-driver?hl=en#start-the-emulator

  2. Follow the README.md for the specific driver, for instance da7219/README.md.
