2 ）编写驱动头文件GUA_ Timer.h
（存放在"......\Projects\MT006_StdPeriph_Templates\GUA"）
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

3 ）工程中添加驱动文件
4 ）在MDK设置中添加驱动源文件路径
2 、添加库的驱动
1）添加库的驱动文件（为了方便一次性都添加进来，已有则不用添加） 
2 ）添加库的驱动头文件（mt006_conf.h 中）（为了方便一次性都添加进来，已有则不用添加）
3 、在应用层中调用
1 ）添加驱动头文件（main.c中）
|------------------------|
| #include "GUA_Timer.h" |
2 ）添加初始化代码（main.c的main函数中）
|----------------------------------------------------------------------------------------------|
| //开定时器 GUA_Timer_Init(); GUA_Timer_Config(Timer_Channel_0, 10000); //通道0,1us*10000=10ms一次中断 |
3 ）添加测试代码（main.c的main函数的while轮询中）
|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| //刚插上usb的第一次要确认充多久电 if(gGUA_ChargeCheck_Read == GUA_CHARGE_CHECK_STATUS_NO_CHARGE) { //从0开始计数，避免过载 gGUA_Timer_Count = 0; gGUA_CurrentTime = 0; //电量<30% 1格以内 充电2小时 if(stGUA_Data.Battery < GUA_ADC_BATTERY_PERCENT_30) { gGUA_ChargeTime = 720000; //100为1秒，2小时 //gGUA_ChargeTime = 2000; //20秒 gGUA_ChargeCheck_Read = GUA_CHARGE_CHECK_STATUS_CHARGING; //正在充电 } //30%<=电量<70% 2格 充电1.5小时 else if((stGUA_Data.Battery >= GUA_ADC_BATTERY_PERCENT_30)&&(stGUA_Data.Battery < GUA_ADC_BATTERY_PERCENT_70)) { gGUA_ChargeTime = 540000; //100为1秒，1.5小时 //gGUA_ChargeTime = 1500; //15秒 gGUA_ChargeCheck_Read = GUA_CHARGE_CHECK_STATUS_CHARGING; //正在充电 } //70%<=电量<100% 3格 充电1小时 else if((stGUA_Data.Battery >= GUA_ADC_BATTERY_PERCENT_70)&&(stGUA_Data.Battery < GUA_ADC_BATTERY_PERCENT_100)) { gGUA_ChargeTime = 360000; //100为1秒，1小时 //gGUA_ChargeTime = 1000; //10秒 gGUA_ChargeCheck_Read = GUA_CHARGE_CHECK_STATUS_CHARGING; //正在充电 } //100%<=电量 不充 else { gGUA_ChargeCheck_Read = GUA_CHARGE_CHECK_STATUS_CHARGE_FULL; //已充满 } } //当计数值相等时充满电 if(gGUA_ChargeTime <= gGUA_CurrentTime) { stGUA_Data.Battery = GUA_ADC_BATTERY_PERCENT_100; //充满先填个理论电压，避免拔掉时显示lo bat gGUA_ChargeCheck_Read = GUA_CHARGE_CHECK_STATUS_CHARGE_FULL; //已充满 //为了不再重复执行,数值拉开 gGUA_CurrentTime = 0; gGUA_ChargeTime = 0xffffffff; //保存数据 GUA_Flash_Control(GUA_FLASH_CONTROL_WRITE); } |
