To help the user develop a custom configurator,
Microchip provides a DLL that uses Microsoft

®

.NET

Framework 3.5. There is documentation about drivers
and utilities on the MCP2200 product page at

www.microchip.com

 (in the Software section) with

information on associating the DLL with a Visual C++
project.

2.3.1

SIMPLE I/O DLL CALLS

 

lists the functions provided by the DLL to

allow the configuration of the device and control of the
I/O.

void InitMCP2200(VID, PID)

bool ConfigureIO(mask)

bool ConfigureIoDefaultOutput(mask, defaultGpioOutputValue)

bool fnRxLED (OFF/TOGGLE/BLINKSLOW/BLINKFAST)

bool fnTxLED (OFF/TOGGLE/BLINKSLOW/BLINKFAST)

bool fnHardwareFlowControl (ON/OFF)

bool fnULoad(ON/OFF)

bool fnSuspend (ON/OFF)

bool ConfigureMCP2200(mask, baudrate, RxLedMode, TxLedMode, flowCtrl, ULoad, suspend)

bool ConfigureIO(mask)

String^ GetDeviceInfo(deviceIndex)

unsigned int GetNoOfDevices()

int GetSelectedDevice()

String^ GetSelectedDeviceInfo()

bool IsConnected()

int SelectDevice(uiDeviceNo)

int ReadEEPROM(uiEEPAddress)

int WriteEEPROM(uiEEPAddress, ucValue)

bool ClearPin(pinnumber)

bool SetPin(pinnumber)

bool ReadPin(pinnumber, *pinvalue)

int ReadPinValue(pinnumber) 

bool ReadPort(*portValue)

int ReadPortValue()

bool WritePort(portValue)

bool SimpleIOClass::ClearPin(unsigned int pin)

bool SimpleIOClass::ConfigureIO (unsigned char IOMap)

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

)

bool SimpleIOClass::ConfigureMCP2200 (unsigned char IOMap, unsigned long BaudRateParam, unsigned 

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

bool SimpleIOClass::fnHardwareFlowControl (unsigned int onOff)

Prior to any DLL API usage, a call to the 

InitMCP2200()

 function is needed. This function is the only 

initialization function in the presented DLL.

The configuration only needs to be set a single time – it is stored in NVM.
