一个关于PCI CAN开发板的windows下的驱动程序,用DDK做的,希望对做PCI CAN板的朋友有用

#include <ntddk.h>
#include "io.h"

int sysOutByte(unsigned int port, int databyte)
{
	// DbgPrint("sysOutByte::port=%2x, data=%2x", port, databyte);
	return _outp(port, databyte);
}

char sysInByte(unsigned int port)
{
	// DbgPrint("sysInByte::port=%2x", port);
	return (char)_inp(port);
}
