Changes
== Installation ==
*Run the fitlet_GPIO_Driver_1.0.exe in Administrator mode and follow the on-screen instructions.
*The GPIO.dll exposes the following functions:
=== GPIO_Config ===
Name: GPIO_Config
Definition: BOOL GPIO_Config(UINT8 gpioNum, UINT8 gpioDir, UINT8 gpioPullUp, UINT8 gpioPullDown)
Description: Confgure the GPIO pin
Arguments:
Return: GPIO pin configuration status (FALSE - failure, TRUE - success)
=== GPIO_Set ===
Name: GPIO_Set
Definition: BOOL GPIO_Set(UINT8 gpioNum, UINT8 gpioValue)
Description: Set the value of GPIO output pin
Arguments:
Return: GPIO output pin configuration status (FALSE - failure, TRUE - success)
=== GPIO_Get ===
Name: GPIO_Get
Arguments:
Return: GPIO input pin value (0 – low, 1 - high)
== Sample Application ==
The following [http://www.fit-pc2.com/download/fitlet/Win7/drivers/fitlet_Win7_GPIO.zip example ] demonstrates the simple control of a GPIO pins. The application writes to GPIO1 (Pin1) and reads from GPIO2 (Pin2) (before using this application connect GPIO1 (Pin1) to GPIO2 (Pin2)).
