使用8051驱动2.0英寸TFT屏幕（S6D0118 IC）

在AVR单片机下通过USART实现串口通讯，里面包含有其配置及源码。-In the AVR microcontroller achieved through USART serial communication, which contains its configuration and source code.

ARM程序，2*2键盘功能，程序可扩展成3*3或4*4的键盘，在LPC2103上测试成功。-ARM procedures, 2* 2 keyboard functions, procedures can be extended into a 3* 3 or 4* 4 keyboard, to test the success of the LPC2103.

单片机用T1中断在IO口P1.0输出乐曲(在P1.0口与VCC间接一喇叭即可听到) 1.由于输出的是方波，比较难听:-)你也可以将波形细分用DA输出正弦波 2.由于T1频繁中断，任何其他中断发生都会是乐曲打顿，只适合试验 3.优化音符编码：一个字节中包含节拍、音符、升降调，可区分数据和命令 -Single-chip microcomputer used in the IO port T1 interrupt output music P1.0 (P1.0 port with VCC in the indirect one can hear the speaker) 1. As the output is a square wave, more bluntly :-) You can also fine-waveform DA output sine wave with sub-2. Due to the frequent interruption of T1, any other interruption occurs Dayton will be playing music, is only suitable for test 3. optimized coding notes: A byte contains rhythms, notes, take-off and landing tune can distinguish between data and command
