MCP2200
2.3
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.
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:

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)

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.
