Hi,

The lcd_demo1.c is not an application for Linux, therefore, you cannot use it directly on Linux. My suggestion is to implement a Linux driver for LCD.

For LED, there are some support in kernel, although they are simple. If you want to implement a driver that can be interfaced by your application, you can refer to the pio button driver in the kernel.
