目前上面是我的GPIO配置结果,
void SetGpioLevel(unsigned int pin, unsigned int data)
[

if (pin < 32)
[
if (data > 0)
[
//GpioDataRegs.GPADAT.all |= (1 << pin);
GpioDataRegs.GPASET.all |= (1 << pin);
]
else
[
//GpioDataRegs.GPADAT.all &= ~(1 << pin);
GpioDataRegs.GPACLEAR.all |= (1 << pin);
]
]
else if (pin < 64)
[
pin = pin-32;
if (data > 0)
[
//GpioDataRegs.GPBDAT.all |= (1 << pin);
GpioDataRegs.GPBSET.all |= (1 << pin);
]
else
[
//GpioDataRegs.GPBDAT.all &= ~(1 << pin);
GpioDataRegs.GPBCLEAR.all |= (1 << pin);
]
]
asm(" NOP");
asm(" NOP");
asm(" NOP");

]

使用这个函数进行控制
int i;
for(i = 0; i < 7; i++)
[
SetGpioLevel(LedStatusGpioPin , 1);
]
其中
volatile Uint16 LedStatusGpioPin[] = [ USER_GPIO42,
USER_GPIO32,
USER_GPIO21,
USER_GPIO13,
USER_GPIO16,
USER_GPIO17,
USER_GPIO29 ];

其中USER_GPIO42 USER_GPIO32 USER_GPIO13可以控制, USER_GPIO21和GPIO16确不受控， 我想输入为高电平， GPADAT 里面确实也为0,不知道为什么, 初始化的时候已经全部配置成 上拉、输出、GPIO功能，但是无作用。
