串口通信该有的都有了,而且样子也不错.大家看后多给意见咯,对了如果有更好的创已请于我联系-the serial communication have some, but looks good. We see multiple views to argue for the better if the founding has been requested to contact me

实现两台机器之间的串口通信！可以对串口进行调试！-achieved between the two machines serial communications! Can serial debugging!

The PCD5003A is a very low power decoder and pager controller specifically designed for use in new generation radio pagers. The architecture of the PCD5003A allows for flexible application in a wide variety of radio pager designs. The PCD5003A is fully compatible with “CCIR Radio paging Code No. 1” (also known as the POCSAG code) operating at data rates of 512, 1200 and 2400 bits/s using a single oscillator crystal of 76.8 kHz. In addition to the standard POCSAG sync word the PCD5003A is also capable of recognizing up to 4 User Programmable Sync Words (UPSWs). This permits the reception of both private services and POCSAG transmissions via the same radio channel. Used together with the Philips UAA2080 or UAA2082 paging receiver, the PCD5003A offers a highly sophisticated, miniature solution for the radio paging market. Control of an RF synthesizer circuit is also provided to ease alignment and channel selection
