摘要
用FPGA+ARM的方式设计低成本加固液晶显示器控制电路。FPGA负责对比度调整,ARM微控制器负责温度、亮度、通信、键盘扫描的控制。创新之处在于用低成本架构取代老方案,缩短开发周期,并引入LED背光源辅助加热、动态背光源降低功耗的思想。
The low-cost ruggedized LCD control circuit is designed with FPGA and ARM. FPGA is used as image contrast processing unit. ARM processor deals with the controls of temperature,luminance, communication and keybroad scanning. The circuit chooses the low-cost arehitecture,decreasing the development cycle.
