2.3.1.2

ConfigureIO

Function:

bool SimpleIOClass::ConfigureIO (unsigned char IOMap)

EXAMPLE 2-2:

2.3.1.3

ConfigureIoDefaultOutput

Function:

bool SimpleIOClass::ConfigureIoDefaultOutput (unsigned char ucIoMap, unsigned char ucDefValue)

EXAMPLE 2-3:

Summary:

Configures the GPIO pins for Digital Input, Digital Output.

Description:

GPIO Pins can be configured as Digital Input, Digital Output.

Precondition:

VID and PID must be previously set via a call to InitMCP2200(VID, PID).

Parameters:

IOMap

- a byte that represents a bitmap of the GPIO configuration:

• a bit set to ‘1’ will be a digital input

• a bit set to ‘0’ will be a digital output

• MSB –

–

LSB

GP7 GP6 GP5 GP4 GP3 GP2 GP1 GP0

Returns:

This function returns True if the transmission is successful and returns False if the transmission fails.

Remarks:

Error code is returned in LastError.

Summary:

Configures the IO pins for Digital Input, Digital Output and also the default output latch value.

Description:

IO Pins can be configured as Digital Input, Digital Output. The default output latch value is received

as a parameter.

Precondition:

VID and PID must be previously set via a call to InitMCP2200(VID, PID).

Parameters:

ucIoMap

- a byte that represents a bitmap used to set the GPIOs as either input or output.

•‘1’ configures GPIO as input

•‘0’ configures GPIO as output

• MSB –

–

LSB

GP7 GP6 GP5 GP4 GP3 GP2 GP1 GP0

ucDefValue

- the default value that will be loaded to the output latch (affects only the pins configured as

outputs).

Returns:

This function returns True if the transmission is successful and returns False if the transmission fails.

Remarks:

Error code is returned in LastError.
