Tiempo de canto ver Smartstrap Tutorial (3 / 4 paso)

Paso 3: Programación del guijarro

1. Configurar una cuenta de piedra en cloudpebble

2. Asegúrese de que el PC y el Smartphone están en la misma red local y luego encienda el desarrollador conexión en tu aplicación para smartphone guijarro tiempo Opciones--> conexión programador
3. Cree un nuevo proyecto vacío, agregue un nuevo archivo de origen denominado "main.c" y luego pone el siguiente código a la misma
