Currently, SCM is moving in the direction of high-performance and multi-species, trends will be further towards the CMOS, low power consumption, small size, large capacity, high performance, low price and built the external circuit and so a number of areas. Which high-speed large capacity single-chip microcomputer in various areas has aroused great repercussion is widely used in intelligent control. Now it features more complete, which is to meet a variety of complex fields, "site control." And the MCS-51 in the field of computer plays an important role.
Designed to achieve this drying plate keyboard vacuum right time and exposure control. Vacuum pre-set time, the exposure time parameters, and the preservation of the EEPROM, Boot automatically read from the EEPROM parameters. Digital vacuum tube time, exposure time, using LED indicates the current state of work. Work with the countdown displays the remaining time to time when the regular, open or close the corresponding relay.
This paper describes the design of the current, mainly used in the AT89C2051, CD4094. 24C02 chip, involving mainly module and control module, and the application of the tools Protel, such as proteus.
