atmega32 和RS485的通讯，已经在电路板上测试通过，RS232相对简单一点，RS485需要对控制收发信号处理一下，并且需要RS232转RS485工具来验证收发是否正确-atmega32 and RS485 communication, has been tested in the circuit board, RS232 relatively simple point, RS485 transceiver control signals need to deal with you, and will need RS232 to RS485 transceiver tools to verify the correctness of

本程序为应用在Arm7下的Ps2键盘接口程序。避免了因多中断而数据出现错误的情况-This procedure is used in ARM7 under the Ps2 keyboard interface program. To avoid interruption caused by more than the case of data error

这是本人最近几年所编写的串行通讯的代码集，可以供大家参考学习。-recent years prepared by the serial communication code sets, we can reference for learning.

用89c2051模拟产生dtmf信号，广泛用于防盗报警、电话数据传输等；节省发号及收号电路，成本低。-with 89c2051 simulation of DTMF signals, widely used in anti-theft alarm, telephone data transmission; Savings and resumption of the circuit, and low cost.
