Contiki 操作系统 : How to read from GIO pin of SKY-mote

Question

我将外部传感器连接到 sky mote 的 GIO 端口。如何从 sky mote 的 GIO pin 获取数据。

PS:我正在使用 contiki 操作系统

P2DIR&= ~0x08; // set the port as input
P2SEL &= ~0x08;                  
P2REN |=  0x08;               
if( (P2IN & 0x08) == 0)
{
 SEND_STRING(&s->sout,"UP");
}
else
{
 SEND_STRING(&s->sout,"Down");
}

帮助我如何从 contiki os 中的 sky mote 的 GIO 引脚读取数据

提前谢谢你。

此代码用于获取 SKY-MOTE 的 GIO2

P2DIR&= ~0x08; // set the port as input
P2SEL &= ~0x08;                  
P2REN |=  0x08;               
if( (P2IN & 0x08) == 0)
{
 SEND_STRING(&s->sout,"UP");
}
else
{
 SEND_STRING(&s->sout,"Down");
}
