PIC单片机的RS232通讯程序

Digitemp Jr. is a device that is designed to measure

and report ambient temperature. When connected to

an RS-232 port on any PC, it will periodically measure

and report in ASCII form the ambient temperature in

degrees Celsius. These temperature readings can be

monitored with any terminal program. If the terminal

program supports capture to disk, the temperature

readings can be saved to disk for further analysis with

a spreadsheet program or other data analysis tool. The

simple ASCII output format of Digitemp Jr. makes it relatively

easy to write custom software for receiving,

recording, and analyzing ambient temperature data.

Best of all, Digitemp Jr. requires no external power supplies

or batteries. It is powered directly by the RS-232

port.
