2.3.1.4

ConfigureMCP2200

Function:

bool SimpleIOClass::ConfigureIoDefaultOutput (unsigned long BaudRateParam, unsigned int RxLEDMode,

unsigned int TxLEDMode, bool FLOW, bool ULOAD, bool SSPND)

EXAMPLE 2-4:

2.3.1.5

fnHardwareFlowControl

Function:

bool SimpleIOClass::fnHardwareFlowControl (unsigned int onOff)

EXAMPLE 2-5:

Summary:

Configures the device.

Description:

Sets the default GPIO designation, baud rate, TX/RX LED modes, flow control.

Precondition:

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

Parameters:

IOMap

- A byte which represents the input/output state of the pins (each bit may be either a ‘1’ for input or ‘0’

for output.

BaudRateParam

- the default communication baud rate.

RxLEDMode

- can take one of the constant values (OFF, ON, TOGGLE, BLINKSLOW, BLINKFAST) to define the

behavior of the Rx LED.

•OFF = 0

•ON = 1

•TOGGLE = 3

•BLINKSLOW = 4

•BLINKFAST = 5

TxLEDMode

- can take one of the defined values (OFF, ON, TOGGLE, BLINKSLOW, BLINKFAST) in order to define the

behavior of the Tx LED.

FLOW

- this parameter establishes the default flow control method (False - no HW flow control, True - RTS/CTS

flow control).

ULOAD

- this parameter establishes when the USB has loaded the configuration.

SSPND

- this parameter establishes when the USB sends the Suspend mode signal.

Returns:

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

Remarks:

None.

Summary:

Configures the flow control of the MCP2200. The flow control configuration will be stored in NVRAM.

Description:

Sets the flow control to HW flow control (RTS/CTS) or no flow control.

Precondition:

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

Parameters:

onOff

•‘1’ if HW flow control is required

•‘0’ if no flow control is required

Returns:

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

Remarks:

Error code is returned in LastError.
