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:
1.
IOMap
- A byte which represents the input/output state of the pins (each bit may be either a ‘1’ for input, and ‘0’
for output.
2.
BaudRateParam
- the default communication baud rate.
3.
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
4.
TxLEDMode
- can take one of the defined values (OFF, ON, TOGGLE, BLINKSLOW, BLINKFAST) in order to define the
behavior of the Tx LED.
5.
FLOW
- this parameter establishes the default flow control method (False - no HW flow control, True - RTS/CTS
flow control).
6.
ULOAD
- this parameter establishes when USB has loaded the configuration.
7.
SSPND
- this parameter establishes when USB send us the Suspend mode.
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.
