I wrote test utility using EVC.

 

A few days ago, I used EVC to test some of the functions of utility, learning and doing it.

1. Test buzzer

 

 

2. Adjust the LCD backlight and implement it by reading and writing the registry.

 

 

3. Test IrDA Communication

 

IRDA setup:

 

4. Get power status

 

 

5. Set and read gpio. You can see that the LED controlled by gpio is highlighted and disabled.

 

I also want to add some other functions. Now I am busy solving other issule. I will write this utility in two days.
