摘要
用超低功耗的微控制器MSP430F1121设计一个嵌入式低功耗的射频/红外转换控制器,该控制器完全由中断事件驱动,在等待用户按键或未接收到无线遥控信号时,系统功耗仅为0.1μA。该控制器能够实现红外遥控信号的自学习及红外-射频信号的自动转换功能,完成对红外遥控设备的控制,实验结果表明:该设计方案能够有效地将无线遥控信号转变为红外遥控信号,并进行有效的控制。
A solution of low-power embedded wireless / infrared conversion controller based on ultra-low power microcontroller MSP430F1121 is proposed. This controller is event-driven entirely by the interrupt and consumes 0.1μA while waiting for the user＇s button-press or not reception of radio frequency remote signal.This controller can realize self-learning of IR remote signal and autotransforming between IR and RF signal,finish to control for the IR remote devices.Experiments validated that the proposed system could effectively convert the wireless remote signals into infrared remote signals with efficient control.
