New page

Open the devices.

==== Prototype ====
int32_t WINAPI VGI_InitGPIO(int32_t DevType, int32_t DevIndex, uint16_t PinMask, uint32_t PinMode); 
==== Parameter ====
'''DevType''': Device type code. For detail, please refer to Device Type Definition Table. 
'''DevIndex''': Device index number. Index number 0 indicates only one device is connected with computer. In case multiple devices are connected, set index number corresponding to the devices required to be openeded. 
'''PinMask''': Reserve parameters which can be set as 0. 
'''PinMode''': 00- ,01- ,10-. 

==== Return code ====
Program execution state. Parameter 0 indicates related function executes successfully. For other return codes' definition, please refer to Error Code Definition Table. 
==== Example ====
#include <stdio.h>
#include "ControlGPIO.h"
int ret;
ret = VGI_InitGPIO(VGI_USBGPIO, 0, VGI_GPIO_PIN7, );
if (ret != ERR_SUCCESS){
printf("Open device error!\n");
return;

		+	The difference between VGI_InitGPIO() and VGI_InitGPIOEx():
		+	VGI_InitGPIO(...) can control Ginkgo series product(with 16 GPIO pins)
		+	VGI_InitGPIOEx(...) can control Ginkgo series product(with 16 GPIO) and Ginkgo Ficus product(more than 16 GPIO pins)
