我发送了8个字节的数据,2500能接收中断能够进去,但是就是RXBYTES会溢出,每次都一样,请大家帮我分析一下原因!!!
程序我再贴一下:
T:
#include "include.h"
extern char paTable[];
extern char paTableLen;
/*发送数据************************************************/
char txBuffer[] =
{0x01 ,0xFE, 0xD6, 0x29, 0x0E, 0x0E, 0x77, 0x88};
/*接收数据************************************************/
char rxBuffer[];
unsigned int i;
void delay_ms(void) //毫秒延时
{
unsigned int i;
for (i=0; i<1500; i++)
{
_NOP();
}
}
void delay_nms(unsigned int n) //延时周期
{
unsigned int i;
for (i=0; i<n; i++)
{
delay_ms();
}
}
void main (void)
{
WDTCTL = WDTPW + WDTHOLD; // 关闭开门狗;
TI_CC_SPISetup(); // 初始化SPI;
TI_CC_PowerupResetCCxxxx(); // 复位 CCxxxx;
writeRFSettings(); // 配置寄存器;
TI_CC_SPIWriteBurstReg(TI_CCxxx0_PATABLE, paTable, paTableLen);//配置功率;
TI_CC_LED_PxDIR = TI_CC_LED1; //点亮LED1;
TI_CC_GDO0_PxDIR &= ~TI_CC_GDO0_PIN; //设置GDO0为输入;
TI_CC_GDO0_PxSEL &= ~TI_CC_GDO0_PIN; //设置P2.6脚为I/O端口;
TI_CC_GDO0_PxIES &= ~TI_CC_GDO0_PIN; //下降沿触发中断;
TI_CC_GDO0_PxIFG &= ~TI_CC_GDO0_PIN; // 清除中断标志;
TI_CC_GDO0_PxIE |= TI_CC_GDO0_PIN; // 使能中断总允许;
TI_CC_SPIStrobe(TI_CCxxx0_SIDLE); //设置芯片为空闲状态;
while(1)
{
delay_nms(500);
TI_CC_LED_PxDIR |= TI_CC_LED2;
TI_CC_SPIStrobe(TI_CCxxx0_SIDLE);
RFSendPacket(txBuffer,8);
delay_nms(50);
TI_CC_LED_PxDIR &= ~TI_CC_LED2;
}
}
