MCP2200
2.3
Simple Configuration and I/O DLL
2.3.1
SIMPLE I/O DLL CALLS
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.
lists the functions provided by the DLL to
allow the configuration of the device and control of the
I/O.

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)
Miscellaneous
String^ GetDeviceInfo(deviceIndex)
unsigned int GetNoOfDevices()
int GetSelectedDevice()
String^ GetSelectedDeviceInfo()
bool IsConnected()
int SelectDevice(uiDeviceNo)
int ReadEEPROM(uiEEPAddress)
int WriteEEPROM(uiEEPAddress, ucValue)
I/O Control
bool ClearPin(pinnumber)
bool SetPin(pinnumber)
bool ReadPin(pinnumber, *pinvalue)
int ReadPinValue(pinnumber)
bool ReadPort(*portValue)
int ReadPortValue()
bool WritePort(portValue)
Summary
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)
Note 1:
2:
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.
