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
