HD7279的程序，从51上移植到avr上面的程序，传上来提供大家参考...

基于ATMGA8515L的PS2 键值显示 -Based on the PS2 keys ATMGA8515L Show

该例程是利用MC9S12DG128中TC0和TC7通道共同完成模拟PWM功能的实例。-The routine is the use of MC9S12DG128 the TC0 and TC7 simulated co-channel PWM function instance.

单片机与电脑通讯，简单的max232代码。-SCM and computer communication, a simple MAX232 code.

C8051F120 ISP下载程序，通过串口可以更新程序，实现硬件的自动升级，更新程序大小为62KB-C8051F120 ISP download programs through the serial port can update procedure, automatic hardware upgrades, updates size is 62KB

三菱梯形图转成51单片机HEX文件。 三菱软件写好梯形图，再运行转换软件，设定好51单片机的输入输出， 打开写好的梯形图，转换出的就是hex文件，烧录到51单片机，51单片机 就可以执行PLC的动作了。51单片机控制板价格便宜，可以代替简单场 合的PLC，控制成本降低。 1：把PWM转换后，在PWM文件下生成一个HEX文件。 2：生成的文件很大，51单片机要选用8K以上(AT89S52就是8K)储存量的。 3：把HEX文件下载到单片机就可以用了。 -Mitsubishi ladder into 51 single-chip HEX file. Mitsubishi software written ladder, and then run the conversion software, set 51 single-chip input and output, open ladder-written, conversion is a hex file, burn to 51 single-chip, 51 single-chip microcomputer can be implementation of the action of PLC. 51 Single-chip panel prices, can replace the simple occasions PLC, control and lower the cost. 1: after the PWM converter, PWM documents generated in a HEX file. 2: generate a lot of paper, 51 single-chip 8K to choose more than (AT89S52 is 8K) storage capacity. 3: The HEX file can be downloaded to a single-chip microcomputer used.

PC机和智能型仪表通过RS485进行异步通信-PC and intelligent instrument for asynchronous communication through the RS485
