想要使用2640模拟串口，发送信息，程序如下：
//定义句柄
static PIN_Handle Uart_PinsHandle = NULL;
static PIN_State My_state;
//引脚的配置数组
PIN_Config MyBoardPinsCfg[] ={
CC2640R2_LAUNCHXL_UART_TX | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX,
PIN_TERMINATE};
void My_Uart_Send(char uContent)
{
int i;
//起始信号，拉低引脚
PIN_setOutputValue( Uart_PinsHandle, CC2640R2_LAUNCHXL_UART_TX, false );
usleep(104);
//数据发送
for(i=0;i<8;i++)
{
PIN_setOutputValue( Uart_PinsHandle, CC2640R2_LAUNCHXL_UART_TX, (uContent & 0x01));
uContent = uContent >> 1;
usleep(104);
}
//结束信号，拉高引脚
PIN_setOutputValue( Uart_PinsHandle, CC2640R2_LAUNCHXL_UART_TX, true );
//多写几个sleep，测试发现sleep少的情况下，很容易出现乱码
usleep(104);usleep(104);usleep(104);usleep(104);usleep(104);
}
//发送字符串
void Send_Word_Func(char *s){
while(*s)
My_Uart_Send(*s++);
}
void main ()
{
char buf[200] = "|8_8|--------------------------*1_1*";
Uart_PinsHandle = PIN_open(&My_state, MyBoardPinsCfg);
PIN_setOutputValue( Uart_PinsHandle, CC2640R2_LAUNCHXL_UART_TX, true );
while(1){
sleep(1);
Send_Word_Func(buf);
}
}
