Interface Driver Development

This paper introduces the Java programming Interface driver in the Android development environment . Includes LED interface and driver, backlight adjustment control program, keyboard interface and driver,UART serial port and communication program,Wi-Fi Interface and communication program,3G interface and driver,MediaPlayer player program, etc.

led Lights by gpio " Span style= "font-family: the song Body;" > interface gpj3_0 and gpj3_1 control. gpio gpio interface control backlight, change timer 0 PWM led backlight brightness adjustment.

on the experimental platform is configured with a matrix keyboard, from gpio interface gph2 and gph3 Port and 3*2 matrix keyboard interface. Keyboard driver Description: 1. virtual memory image and device resource configuration; 2. cache initialization configuration and gpio set; 3. Configure the keyboard as an input device and register the keyboard driver; 4. 5. interrupt scan.

Insert the WI-FI+BT+FM triple wireless card on the experimental platform to achieve Wi-Fi settings. The so-called Wi-Fi, an industry term published by an organization called the Wireless Ethernet Compatibility Consortium, is a short-range wireless transmission technology that can support Internet-connected radio signals within hundreds of meters, and people also call Wi-Fi for wireless broadband. 3G is a communication technology standard, all called 3rd Generation, is the wireless communication and the Internet and other multimedia communications to combine the new generation of mobile communication system.
