DS18B20程序(LJD-SY-5100单片机程序) 控制DS18B20完成芯片的控制和数据传输-DS18B20 procedures (LJD-SY-5100 single-chip process) control chip DS18B20 complete control and data transmission

单片机最小系统，两位LED数码管由串口输出接两个164驱动，Lout,Rout为左右声道输出，SET， ALT0， ALT1为三个按键，也可自己在开始的I/O定义改成你想用的I/O口；12M晶振，若用89C51则只可装下约14首歌曲，用89C52则可装下近40曲-The smallest single-chip system, the two LED digital tube by the serial output driver 164 then two, Lout, Rout output for the left and right channels, SET, ALT0, ALT1 three buttons can also be their own at the beginning of the I/O definition change you want to use the I/O port 12M crystal, if one uses a 89C51 only loaded about 14 songs can be loaded with 89C52 under near 40

ICCAVR下的红外解码程序，包括全部源码，还有原理图和PCB图，以及主要芯片资料-Under the infrared ICCAVR decoding procedures, including all source code, as well as PCB schematics and maps, as well as major chipset information
