单片机C8051F040与MAX5322（D/A芯片）的应用程序

周立功 smartArm2200 的基于uCOS-II的综合实验源程序，绝对物有所值-Week smartArm2200 Ligong uCOS-II based on a comprehensive experimental source, the absolute value for money

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

自制小时钟 可以遥控调节时间，采用315M 2262 ，2272 收发模块 发来给新手看看 -Self-made small-time clock can be adjusted remotely, using 315M 2262, 2272, sent to the transceiver module to see if novice

单片机读写E2P程序 利用单片机和2402连接,向2402内写入一串数据,单片机通过按键来将写入的数据读出来 用LED显示-E2P procedures to read and write single-chip single-chip computer and 2402 connected to 2402 with a string of data to write, microcontroller through the keys to write the data will be read out with LED display

这是我用C语言写的一个数字钟，他可以实现多种闹钟和秒表功能-This is because I use C language written in a digital clock, he can achieve a variety of alarm and stopwatch functions, etc.
