【正文】 cuit, PC machine and monolithic integrated circuit serial port munication channel and some interface circuit. The monolithic integrated circuit through carries on corresponding processing to the signal, thus realizes the temperature control goal. In the article also emphatically introduced the software design part, uses the modular structure in here, the main module includes: Nixietube display sequence, keyboard scanning and pressed key disposal procedure, temperature signal processing procedure, blackwhite control procedure, excess temperature warning procedure.
