msp430f149单片机与nrf905串口通信，这是发送节点的c语音程序-msp430f149 MCU and nrf905 serial communication, which is sending node c voice procedures

基于MSP430F149的温湿度传感器DHT21（又名AM2301）控制程序。 说明：空闲时单片机处于LPM3,若串口收到有效命令唤醒单片机开启采集，温湿度值以字符形式发送到串口，用串口调试助手即可观察。-Temperature and humidity sensors based on MSP430F149 DHT21 (also known as AM2301) control procedures. Note: when the MCU is in idle LPM3, if the
