In recent years, with the field of computer penetration in the community and the development of large-scale integrated circuits, ARM MCU applications are continually deepening, as it has a strong functions, small size, low power consumption, cheap, reliable, the use of easy, so particularly suitable for control of the system and, more widely used in automatic control, intelligent instruments, meters, data acquisition, military products, as well as the fields of household appliances, ARM is often as a single-chip the core components to use, in accordance with the specific hardware architecture, as well as application-specific features of the software object to be perfect.
In this development trend, the system chosen for the digital control unit 89S52, 100KV high voltage power supply on an acquisition, and display data and send functions.
