1、无线龙（）4协议栈CC243（）单片机串口测试实验（UART）程序：1、《main.c》#dcfincENABLE_ALL_INTERRUPT()(IENO1=0x80)#defineDISABLE.ALL_INTERRUPT()(IENO&=-0x80)#include,,ioCC2430.hn#defineucharunsignedchar#defineuintunsignedint#defineBYTEunsignedcharexternvoidLARTxISRopcn(void);〃开串口接收中断服务函数externvoidSET
2、_UARTO_ISR(void);//冷口中断接收设置函数externoidnitUART(void);〃初始化函数main(void){uchartemp=0;SLEEP&二-0x04;//reset2:Bothoscillatorspoweredupwhile(!(SLEEP&0x40));//XOSCispoweredupandstable等待起振CLKCON&=〜0x47;//reset6:Mainclockoscillatorselect:32MHzcrystaloscillatorSLEEP1=0x04;//set2:Osc
3、illatornotselectedbyOSCbitpowereddown〃先让两个振荡器都起振；等待品体振荡器起振并稳定;〃通过CLKCON的OSC位把主时钟选择32M晶体振荡器；〃再让没有被CLKCON的OSC位选择的振荡器停止起振(关RC振荡器)initUARTO;〃初始化UARTxISRopenO;〃开串口屮断ENABLE_ALL_INTERRUPT();//开全局中断whilc(l);振荡器起振稳定——＞设置主时钟——＞初始化串口——＞开串口中断——＞开全局中断//2、《uart・c》#includenioCC2430.hHun

7、,UART可由这两线组成,也可再加上RT,CT这两条else//讦U0CFG=0,choselocation1POSEL1=OxOC;//thenPO.2/3setasperipheralI/O；同样为RX,TX两线}}else//ifuart=l,choseUSART1_UART/SP1{if(PERCFG&0x02)//ifU1CFG=1,choselocation2{P1SEL1=OxCO;//thenPl.6/7jeta;pa*ipheralIO}else//ifU1CFG=O,choselocation1{
8、POSEL1=0x30;//thenPO.4/5st3peripheralIO}}〃以上进行USATR通道选择设置//##中间的uart根据上而的设置为0或1U##uart##GCR=B
