1、MTK Driver Introduction,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 = TRUE Option.mak文件中 ifdef DRV_CUSTOM_TOOL_SUPPORTifeq ($(strip $(DRV_CUSTOM_TOOL_SUPPORT),TRUE)COM_DEFS += _CUST_NEW_endif endif,2.

2、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.c void GPIO_init(void) 操作1. 写状态a. 模式修改GPIO_ModeSetup(kal_uint16 pin, kal_uint16 conf_dada)b. 方向修改void GPIO_InitIO(char direction, char port)c. 置高与置低GPIO_WriteIO(char data, char port
3、),d. 上拉与下拉的使能 void GPIO_PullenSetup(kal_uint16 pin, kal_bool enable)2. 读取状态a. 返回模式 char GPIO_ReturnMode(char port);b. 返回方向 char GPIO_ReturnDir(char port);c. 返回电平值 char GPIO_ReturnDout(char port); 3. GPIO使用中需注意的问题,二.中断的配置与使用,. 中断个数8个 EINT0, EINT1为专用中断, EINT2-7 与GPIO等功能复用. 设置中断模式通过DRV_TOOL或Gpio_init(v
