1、MTKDriverIntroduction首先需要注意两个宏定义1.__CUST_NEW__程序中有多处用该宏将代码隔开Make文件中若如下定义：DRV_CUSTOM_TOOL_SUPPORT=TRUEOption.mak文件中ifdefDRV_CUSTOM_TOOL_SUPPORTifeq($(strip$(DRV_CUSTOM_TOOL_SUPPORT)),TRUE)COM_DEFS+=__CUST_NEW__endifendif2.WIN32#ifndefWIN32………………#endif用该宏将真机与模拟器的代码分隔开一
2、.GPIO口的初使化与使用<1>GPIO口的初始化方法：两种：1.工具customdrvDrv_ToolDrvGen.exe修改：customdrvmisc_drvIWIT23_NEP_07A_PMJ_BBcodegencodegen.dws2.程序中修改：Gpio_drv.cvoidGPIO_init(void)<2>操作1.写状态a.模式修改GPIO_ModeSetup(kal_uint16pin,kal_uint16conf_dada)b.方向修改voidGPIO_InitIO(chardirectio
3、n,charport)c.置高与置低GPIO_WriteIO(chardata,charport)d.上拉与下拉的使能voidGPIO_PullenSetup(kal_uint16pin,kal_boolenable)2.读取状态a.返回模式charGPIO_ReturnMode(charport);b.返回方向charGPIO_ReturnDir(charport);c.返回电平值charGPIO_ReturnDout(charport);3.GPIO使用中需注意的问题二.中断的配置与使用<1>.中断个数8个EINT0,EIN
4、T1为专用中断,EINT2-7与GPIO等功能复用<2>.设置中断模式通过DRV_TOOL或Gpio_init(void)来初始化，也可在程序中通过GPIO_ModeSetup(kal_uint16pin,kal_uint16conf_dada)随时修改<3>.中断注册函数在某个TASK中注册中断，建议注册在AUX_TASK中，便于管理EINT_Registration(FLICK_EINT_NO,KAL_TRUE,flick_state,FLICK_EINT_HISR,KAL_TRUE);<4>.中断处理函数以FLICK及BA
5、TTERY两个中断为例：voidFLICK_EINT_HISR(void)//addedbyJeffJi071024{ilm_struct*flick_ilm;aux_id_struct*aux_id_data;if(flick_state==LEVEL_HIGH){aux_id_data=(aux_id_struct*)construct_local_para(sizeof(aux_id_struct),TD_CTRL);aux_id_data->aux_id=AUX_ID_FLICK_OFF;DRV_BuildPrimiti
