Simple Configuration and I/O DLL

A DLL is provided by Microchip to help the user

develop a custom configurator. See the documentation

on the MCP2200 product page for details on

associating the DLL with a Visual C++ project.

2.3.1

SIMPLE I/O DLL CALLS

The DLL provides the following functions to allow

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

2.3.1.1

Initialization

void InitMCP2200(VID, PID)

bool IsConnected()

2.3.1.2

Configuration (only needs to be set

once; stored in NVM)

bool ConfigureIOPins(mask)

bool fnRxLED (On/Off, Toggle/Blink, 100/

200mS)

bool fnTxLED (On/Off, Toggle/Blink, 100/

200mS)

bool fnHardwareFlowControl (On/Off)

bool fnUSBcfg(on/off)

bool fnSuspend (on/off)

bool SetBaudRate (baudrate)

bool ConfigureAll (TRISmask, RxLED, TxLED,

RxTGL, TxTGL, LEDX, FLOW, USBCFG, SSPND,

BaudRate)

2.3.1.3

I/O Control

bool ClearPin(pinnumber)

bool ReadPin(pinnumber)

bool SetPort (portValue)

bool ReadPort(*portValue)

bool WriteEEPROM (Address, Data)

bool ReadEEPROM (Address)

2.3.1.4

Summary

Summary:

SimpleIOClass::InitMCP2200 (unsigned int

VendorID, unsigned int ProductID)

bool SimpleIOClass::ConfigureMCP2200

(unsigned char IOMap,

unsigned long BaudRate,

unsigned int

RxLED,

unsigned int

TxLED,

bool

Hardware Flow Control,

bool

USBCFG pin function,

bool

Suspend pin function)

bool SimpleIOClass::SetPin(unsigned int pin)

bool SimpleIOClass::ClearPin(unsigned int

pin)

bool SimpleIOClass::ReadPin(unsigned int pin,

unsigned int *returnvalue)

bool SimpleIOClass::WritePort(unsigned int

value)

bool SimpleIOClass::ReadPort(unsigned int

*returnvalue)

While ConfigureMCP2200 configures the device

with one call, it may also be configured one

parameter at a time:

bool SimpleIOClass::fnRxLED (unsigned int

mode)

bool SimpleIOClass::fnTxLED (unsigned int

mode)

bool SimpleIOClass::fnHardwareFlowControl

(unsigned int onOff)

bool SimpleIOClass::fnUSBCFG (unsigned int

onOff)

bool SimpleIOClass::fnSuspend (unsigned int

onOff)

bool SimpleIOClass::fnSetBaudRate (unsigned

long BaudRateParam)

bool SimpleIOClass::ConfigureIO (unsigned

char IOMap)

Constants:

const unsigned int OFF = 0;

const unsigned int ON = 1;

const unsigned int TOGGLE = 3;

const unsigned int BLINKSLOW = 4;

const unsigned int BLINKFAST = 5;

2.3.1.5

InitMCP2200

SimpleIOClass::InitMCP2200 (unsigned int

VendorID, unsigned int ProductID)

Configures the Simple IO class for a specific

Vendor and product ID.

Parameters:

Vendor ID - Assigned by USB IF (www.usb.org)

Product ID - Assigned by the Vendor ID

Holder

Returns:

none

Example:

InitMCP2200 (0x04D8, 0x00DF);

2.3.1.6

ConfigureMCP2200

bool SimpleIOClass::ConfigureMCP2200

(unsigned char IOMap,

unsigned long BaudRate,

unsigned int

RxLED,

unsigned int

TxLED,

bool

Hardware Flow Control,

bool

USBCFG pin function,

bool

Suspend pin function)

Configures the device's default baudrate,

GPIO configuration and pin functions.

Other

functions set each parameter one at a time.

This configures the part in one call.

Precondition:

The Vendor and Product ID must have been

specified by SimpleIOInit.
