(FTC_HANDLE ftHandle, BOOL bControlLowInputOutputPins, PFTC_INPUT_OUTPUT_PINS pLowInputOutputPinsData, BOOL bControlHighInputOutputPins, PFTC_INPUT_OUTPUT_PINS pHighInputOutputPinsData)
|
Parameters
|
ftHandle
|
Handle of the device.
|
|
bControlLowInputOutputPins
|
Enables or disables the lower 4 GPIO pins.
|
|
pLowInputOutputPinsData
|
Pointer to a structure that contains the data that is used to control the lower 4 GPIO pins of the FT2232C device.
|
|
bControlHighInputOutputPins
|
Enables or disables the upper 4 GPIO pins.
|
|
pHighInputOutputPinsData
|
Pointer to a structure that contains the data that is used to control the upper 4 GPIO pins of the FT2232C device.
|
Return Value
FTC_SUCCESS if successful, otherwise the return value is one of the following FTC error codes:
FTC_INVALID_HANDLE
FTC_NULL_INPUT_OUTPUT_BUFFER_POINTER
FTC_FAILED_TO_COMPLETE_COMMAND
FTC_IO_ERROR
Remarks
This function provides complete control over the state of the 8 general purpose input/output (GPIO) pins. They can be configured to be inputs, low outputs or high outputs. The state of the pins can be read using the JTAG_GetGPIOs function.
The definition of the FTC_INPUT_OUTPUT_PINS structure is given in the Appendix.
Example
FTC_STATUS Status = FTC_SUCCESS;
FTC_HANDLE ftHandle;
FTC_INPUT_OUTPUT_PINS LowInputOutputPinsData;

LowInputOutputPinsData.bPin2InputOutputState = true;
LowInputOutputPinsData.bPin3InputOutputState = true;
LowInputOutputPinsData.bPin4InputOutputState = true;
// Set low byte bins as high
LowInputOutputPinsData.bPin1LowHighState = true;
LowInputOutputPinsData.bPin2LowHighState = true;
LowInputOutputPinsData.bPin3LowHighState = true;
