MCP2200
Precondition:
The Vendor and Product ID must have been
specified by SimpleIOInit.
Parameters:
IOMap - one byte, with each bit corresponding
to each GP pin. 0 for output, 1 for input.
Returns:
Function returns true if the transmission is
successful, returns False if there the
transmission fails.
Example:
<code>
if
(SimpleIOClass::ConfigureGPIO(OutputPacketBuf
fer) == SUCCESS)
lblStatusBar->Text = "Success";
else
lblStatusBar->Text = "Invalid command
" + SimpleIOClass::LastError;
</code>
2.3.1.15
ClearPin
bool SimpleIOClass::ClearPin(unsigned int
pin)
Summary:
Clears the specified pin.
Description:
Sets the specified pin to zero.
Precondition:
Must have previously been configured as an
output via a ConfigureGPIO call.
Parameters:
pin - The pin number to set (0-7)
Returns:
Function returns true if the transmission is
successful, returns False if there the
transmission fails.
Example:
<code>
if (SimpleIOClass::ClearPin (2))
{
lblStatusBar->Text = "Success";
}
else
lblStatusBar->Text = "Invalid command
" + SimpleIOClass::LastError;
</code>
Remarks:
none
2.3.1.14
SetPin
bool SimpleIOClass::SetPin(unsigned int pin)
Summary:
Sets the specified pin.
Description:
Sets the specified pin to one.
Precondition:
Must have previously been configured as an
output via a ConfigureGPIO call.
Parameters:
pin - The pin number to set (0-7)
Returns:
Function returns true if the transmission is
successful, returns False if there the
transmission fails.
Example:
<code>
if (SimpleIOClass::SetPin (2))
{
lblStatusBar->Text = "Success";
}
else
lblStatusBar->Text = "Invalid command
" + SimpleIOClass::LastError;
</code>
Remarks:
none
2.3.1.16
ReadPin
bool SimpleIOClass::ReadPin(unsigned int pin,
unsigned int *returnvalue)
Summary:
Reads the specified pin.
Description:
Reads the specified pin and returns the value
in returnvalue. If the pin has been
configured as Digital Input, the return value
will be either 0 or 1. If the pin has been
configured as Analog Input, the pin will be
read by the ADC and return a 10 bit value,
right justified.
Precondition:
Must have previously been configured as an
input via a ConfigureGPIO call.
Parameters:
pin - The pin number to set (0-7)
returnvalue - the value read on the pin (0 or
1)
