今天，做了 一個點亮arm ep9315的led燈的wince應用程序，是用evc4.0用的，為了這個小程序，花了我4天時間
主要是以前沒有做過wince的應用程序。光裝evc4.0就用了 我2天時間，剛開始裝evc4.0，沒有裝evc4.0 sp3,ep9315sdk包用不成，已選就死機，后來發(fā)現(xiàn)是沒裝evc4 sp3的緣故，裝了一個后，就不死機了，感覺很興奮。

又長了一個知識點。
下面是我在evc下驅(qū)動arm gpio的例子
BOOL ChangeGreenLed (void)
{
int fd;
unsigned char *gpio_base;
unsigned int *gpio_PEDDR, *gpio_PEDR;

OutputDebugString(L"TestDrv - LedDrive1\n");

//PUCHAR ioPortBase;
PHYSICAL_ADDRESS PortAddress = {0x80840000, 0};
gpio_base =(PUCHAR) MmMapIoSpace( PortAddress, 0x80,FALSE );

gpio_PEDR = (unsigned int *)(gpio_base + 0x20);
gpio_PEDDR = (unsigned int *)(gpio_base + 0x24);

*gpio_PEDR ^= 0x1;

for(int x = 0; x< 10 ; x++)
{
//gpio_PEDDR = 0xffffffff; // set port E to all output
*gpio_PEDR ^= 0x00000001; // invert green LED state

printf("PEDR = %d\n", *gpio_PEDR);

Sleep(1000);
}


OutputDebugString(L"TestDrv - LedDrive2\n");

return TRUE;
}

如果編譯不過，可加上ceddk.h和ceddk.lib兩個文件，就可以了。祝大家學習wince 快樂 。

#include <ceddk.h>
#pragma comment(lib,"ceddk.lib")
void OutPortFun(WORD wAddr,byte bValue)
{
PHYSICAL_ADDRESS IoAddress;
IoAddress.LowPart = wAddr;//硬件地址
IoAddress.HighPart = 0;
UCHAR * gpioPtr;
gpioPtr = ( UCHAR *)MmMapIoSpace( IoAddress,1,FALSE );
WRITE_PORT_UCHAR(gpioPtr,bValue);
}
