Title The Distributed Control System of Switch Array on Single-Chip
Abstract
This article is to introduce the C8051F020 microcontroller to control the antenna switch array. Antenna technology is now widely used in civilian and military communications. Its array of switch control is an important technology. Data transmitting and receiving complete with antenna switch off and on.
On the basic principles of the basic principles of the antenna and radio frequency (RF) switch, Continue to explore the design method for single-pole four-position switch, the main performance and the method for control switch. This article select Silicon Laboratories' C8051F020 microcontroller to control switch array. C8051F MCU is a typical high-performance single-chip and a fully integrated mixed-signal system-on-chip. It is fully compatible with MCS-51 instruction kernel. Hardware to connect with the host computer via the RS232 electrical interface standard. Its communication protocol using the UART. This article debugs programs in KEIL uVision2. After debugging through the hardware connection and GPIO transfer to the 30 switches. The final host computer and distributed control of the antenna switch array.
This article has the C8051f020 microcontroller part of the hardware and software debugging. Experiments show that designed hardware and software scheme is feasible, Operating normally, stable and reliable.
Keywords: Switch Array,Single Chip, UART protocol, Single-pole four set
