基于聚芯SoC北斗时钟的程序流程2（2）-Syslib.c中的sysInit定制部分-无线模块选取

在系统初始化之后，需要进行ZigBee无线模块的选取，因为在系统中可以集成成都无线龙的ZigBee模块，还有上海的悦动05无线模块。因为无线龙的模块需要按键（超过1秒）才能选定，所以在程序中20*1000usdelay，也就大约20ms。SELECT_MODULE_MAX_WAIT_COUNT=5000，所以这个块的最大的延迟时间就是在非无线龙的模块时，需要最多延时5000*1000us=5s。

while(SelectModuleWaitCount <= SELECT_MODULE_MAX_WAIT_COUNT)
{
while(!erasoc_gpio_read(5))        // have a key
{
PressCount++;
delay(1000);
SelectModuleWaitCount++;
}
if(PressCount >= 20)
{
PressCount = 0;
sysPrintf("Select module:trigger a key!/n");
SendMsgMode = WXL_FLYRF;
sysPrintf("SendMsgMode:%d/n", SendMsgMode);
break;
}
PressCount = 0;    //clear increased PressCount because of key jitter
delay(1000);
SelectModuleWaitCount++;
}

如果选择的是“无线龙”模块需要进行一些配置，而上海的悦动模块不需要进行配置。在无线龙的模块的配置过程中，需要保证配置成功，因此用了C语言不提倡的goto语句。主要是对发送了一些Config Command的一些步骤：//set channel number，//set panid number，//set device type//reset system//start a network

/*const u8 ConfigCmd[][CMD_LENTH] = {
{0xFE,0x00,0x13,0x02,0x00,0x01,0x13,0xFF},    //read mac address
{0xFE,0x00,0x12,0x07,0x00,0x84,0x04,0x00,0x80,0x00,0x00,0x14,0xFF},//set channel number
{0xFE,0x00,0x12,0x05,0x00,0x83,0x02,0x01,0x00,0x15,0xFF},    //set panid number
{0xFE,0x00,0x12,0x04,0x00,0x87,0x01,0x00,0x11,0xFF},        //set device type
{0xFE,0x00,0x05,0x01,0x00,0x01,0xFF},    //reset system
{0xFE,0x0A,0x18,0x00,0x11,0xFF},        //start a network
{0xFE,0x00,0x14,0x01,0x00,0x11,0xFF},    //read device information
{0xFE,0x01,0xA0,0xFF}
