2.3.1.2
ConfigureIO
Function:
bool SimpleIOClass::ConfigureIO (unsigned char IOMap)
EXAMPLE 2-2:
2.3.1.3
ConfigureIoDefaultOutput
Function:
bool SimpleIOClass::ConfigureIoDefaultOutput (unsigned char ucIoMap, unsigned char ucDefValue)
EXAMPLE 2-3:
Summary:
Configures the GPIO pins for Digital Input, Digital Output.
Description:
GPIO Pins can be configured as Digital Input, Digital Output.
Precondition:
VID and PID must be previously set via a call to InitMCP2200(VID, PID).
Parameters:
IOMap
- a byte that represents a bitmap of the GPIO configuration:
a bit set to ‘1’ will be a digital input
a bit set to ‘0’ will be a digital output
MSB –
LSB
GP7 GP6 GP5 GP4 GP3 GP2 GP1 GP0
Returns:
This function returns True if the transmission is successful and returns False if the transmission fails.
Remarks:
Error code is returned in LastError.
Summary:
Configures the IO pins for Digital Input, Digital Output and also the default output latch value.
Description:
IO Pins can be configured as Digital Input, Digital Output. The default output latch value is received
as a parameter.
Precondition:
VID and PID must be previously set via a call to InitMCP2200(VID, PID).
Parameters:
1.
ucIoMap
- a byte that represents a bitmap used to set the GPIOs as either input or output.
1’ configures GPIO as input
0’ configures GPIO as output
MSB –
LSB
GP7 GP6 GP5 GP4 GP3 GP2 GP1 GP0
2.
ucDefValue
- the default value that will be loaded to the output latch (affects only the pins configured as
outputs).
Returns:
This function returns True if the transmission is successful and returns False if the transmission fails.
Remarks:
Error code is returned in LastError.
