EXAMPLE 2-8:

2.3.1.9

fnTxLED

Function:

bool SimpleIOClass::fnTxLED (unsigned int mode)

EXAMPLE 2-9:

2.3.1.10

fnULoad

Function:

bool SimpleIOClass::fnULoad (unsigned int onOff)

EXAMPLE 2-10:

Summary:

Configures the Tx LED mode. Tx LED configuration will be stored in NVRAM.

Description:

Sets the Tx LED mode to one of the possible values.

Precondition:

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

Parameters:

mode (constant)

: OFF, TOGGLE, BLINKSLOW, BLINKFAST

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 GP1 pin of the MCP2200 to show the status of the USB configuration.

Description:

When the GP1 is designated to show the USB configuration status, the pin will start low (during

power-up or after Reset), and it will go high after the MCP2200 is successfully configured by the

host.

Precondition:

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

Parameters:

onOff:

• ‘1’ GP1 will reflect the USB configuration status

•‘0’ GP1 will not reflect the USB configuration status (can be used as GPIO)

Returns:

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

Remarks:

Error code is returned in LastError.
