Created page with "Init the devices. ==== Prototype ==== int32_t WINAPI VGI_InitGPIOEx(int32_t DevType, int32_t DevIndex, uint16_t PinMask, uint32_t PinMode); ==== Parameter ==== '''DevType..."

New page

Init the devices.

==== Prototype ====
int32_t WINAPI VGI_InitGPIOEx(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''': Pins need to set logical level. In case the corresponding bit is 1, set the logical level of relative GPIO pins. E.g. when PinMask is 0x0001, can set logical level of GPIO_0. When PinMask is 0x0102, can set logical level of both GPIO_1 and GPIO_8. Can't set the other pins. 
'''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;
//GPIO functional description
#define INPUT_PULL_UP 0 // Input pull-up
#define OUTPUT_PUSH_PULL 1 // Output push-pull
#define OUTPUT_OPEN_DRAIN 2 // Output open-drain
#define INPUT_FLOATING 3 // Input floating
// Set GPIO_7 and GPIO_8 to output(push-pull)
#define PINMASK (VGI_GPIO_PORTA|VGI_GPIO_PIN7)
ret = VGI_InitGPIOEx(VGI_USBGPIO, 0, PINMASK, 0x55555555);
/*
0x55 55 55 55 = 0b01010101 01010101 01010101 01010101
0b01 means OUTPUT_PUSH_PULL
*/
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)
