Title Microcontroller Based MSP430F5438A agricultural monitoring systems - Hardware Design
Abstract
MSP430F5438A chip design agricultural monitoring system that can automate operations and information management, in order to reduce production costs, improve production efficiency based. MSP430 MCU from the launch date has ten years of history, the size, cost and power consumption have reached a high level, which has been widely used in the fields of intelligent instruments, automatic control equipment. Data acquisition circuit design, complete MSP430F5438 microcontroller minimum system design. According to the functional requirements and performance monitoring system for agriculture, use MSP430F5438A microcontroller as the master controller chip, expanded, including clock module, memory module, A/D converter circuit, the communication circuit monitoring system, including peripheral modules, and each modules in detail circuit design to ensure the reliability and performance of hardware. Finally, the function of the system debugging, you can see under the control of a system controller, the system can be completed automatically, data collection and other expected features.
