用C实现数字电压电流表：1、由外部输入直流电压电流，电压范围20V，电流范围1A； 2、电压/电流通过开关切换； 3、显示：数码管显示电压值/电流值，精...

用AVR 音乐合成： 1.音乐数据存放于芯片的flash存贮器中2.PA口显示不同的音阶变化。 3.音乐数据的低四位选择音调频率，高四位*5后，为音调持续时间。-Using AVR Music Synthesis: 1. The music data stored in flash memory chips in the mouth 2.PA show different changes in scale. 3. The music data to choose the four tones of low frequency, high 4* 5, in order to tone duration.

实验采用七段码LED设计（数码管），显示直观；采用定时器中断，计时更准确；功能齐全，可随时启动、停止、清零，后者智能化程度更高。-Seven-Segment LED code using the experimental design (digital control), visual display using timer interrupt, a more accurate time functions, may at any time to start, stop, cleared, and the latter an even higher degree of intelligence.

C8051F120初始化SPI，启动CC2420。通过将CC2420 得VREG_EN 引脚置位高电平使能Voltage regulator，等待其稳定；然后重新启动CC2420 芯片，等待晶振起振。-Initialize SPI, start the CC2420. By CC2420 have VREG_EN pin high to enable the set Voltage regulator, waiting for their stability and then re-start the CC2420 chip, since waiting for crystal oscillator.
