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.
2.3.1.1
Function:
ClearPin
bool SimpleIOClass::ClearPin (unsigned int pin)
Summary:
Description:
Precondition:
Parameters:
Returns:
Remarks:
Clears the specified pin.
Clears the specified pin to logic ‘
0
’.
This pin must be previously configured as an output via a
ConfigureIO
or
ConfigureIoDefaultOutput
call.
pin
- The pin number to set (0-7).
This function returns True if the transmission is successful and returns False if the transmission fails.
None
EXAMPLE 2-1:
if (SimpleIOClass::ClearPin (2))
{
lblStatusBar->Text = “Success”;
}
else
lblStatusBar->Text = “Invalid command ” +
SimpleIOClass::LastError;
