为什么我像stm32一样修改引脚代码，mpu6050就驱动不起来。
首先初始化GPIO
EALLOW;
GpioCtrlRegs.GPAMUX1.bit.GPIO0 = 0;
GpioCtrlRegs.GPAMUX1.bit.GPIO1 = 0;
GpioCtrlRegs.GPAQSEL1.bit.GPIO0=0;
GpioCtrlRegs.GPAQSEL1.bit.GPIO1=0;
GpioCtrlRegs.GPAPUD.bit.GPIO0 = 0;
GpioCtrlRegs.GPAPUD.bit.GPIO1 = 0;
GpioCtrlRegs.GPADIR.bit.GPIO0=1;
GpioCtrlRegs.GPADIR.bit.GPIO1=1;
EDIS;
然后再MPU6050上修改代码如下
#define SDA_1 GpioDataRegs.GPASET.bit.GPIO0=1//SDA=1
#define SDA_0 GpioDataRegs.GPACLEAR.bit.GPIO0=1//SDA=0
#define SCL_1 GpioDataRegs.GPASET.bit.GPIO1=1//SCL=1
#define SCL_0 GpioDataRegs.GPACLEAR.bit.GPIO1=1//SCL=0
#define SDA_DIR_IN GpioCtrlRegs.GPADIR.bit.GPIO0=0//SDA设置成输入
#define SDA_DIR_OUT GpioCtrlRegs.GPADIR.bit.GPIO0=1//SDA设置成输出
#define SCL_DIR_OUT GpioCtrlRegs.GPADIR.bit.GPIO1=1//SCL设置成输出
#define SDA_read GpioDataRegs.GPADAT.bit.GPIO1//取出SDA上的数据
