  • Linux (tested on Ubuntu 18.04.1)
  • C / C++
  • Command line
  • Pico SDK
  • Docker (optional)
  • LVGL

Installation

cd <your projects folder>
git clone https://www.github.com/deshrike/pico-waveshare
cd pico-waveshare
git submudule update --init

Pico SDK

You can compile the Pico programs locally, or using Docker.

To compile locally, install the Pico SDK.

To use a Docker image, follow these steps:

cd <your projects folder>
mkdir pico-waveshare
docker run -d -it --name pc1 --mount type=bind,source=${PWD},target=/home/dev lukstep/raspberry-pi-pico-sdk:latest

After a reboot, you will need to restart the container:

docker start pc1

Connect to the Docker container:

docker exec -it pc1 /bin/sh

Inside the Docker container:

cd /home/dev/pico-waveshare

Compiling

cd /home/dev/pico-waveshare  (if using Docker)
cd <your projects folder>/pico-waveshare (if you have installed the Pico SDK locally)

cd cdjwatch
mkdir build
cd build
cmake ..
make

The build folder should now contain a file called cdjwatch.uf2. Copy this file to the device.

Follow the same steps for the other examples: blink, canvastest and lvgltest.

Examples

blink

Pico example to blink the on-board LED (Backlight).

lvgltest
