PHIDGET devices

Installation

Phidget

• Get latest library and example packages
  • libphidget_2.1.8.20120131.tar.gz
  • phidget21-c-examples_2.1.8.20120131.tar.gz
• configure, make, make install the library package.
• Possible missing of the phidget21.h (had to download it separately).
• During compilation, possible missing declaration, in this case add to the phidget21.h the following declarations:

#include <stdint.h>

#define __declspec(x)
#define __stdcall
#define __int64 uint64_t
#define CCONV

Build

• from the examples:

gcc Analog-simple.c -o Analog-simple -pthread -lphidget21

Operation

• In this example, the 4 DACs are available with functions for setting the DAC(voltage) and a channel enable.

	CPhidgetAnalog_setVoltage(analog, 0, 1.0);
        CPhidgetAnalog_setVoltage(analog, 1, 2.0);
        CPhidgetAnalog_setVoltage(analog, 2, 3.0);
        CPhidgetAnalog_setVoltage(analog, 3, 4.0);
	CPhidgetAnalog_setEnabled(analog, 0, PTRUE);
        CPhidgetAnalog_setEnabled(analog, 1, PTRUE);
        CPhidgetAnalog_setEnabled(analog, 2, PTRUE);
	CPhidgetAnalog_setEnabled(analog, 3, PTRUE);

• For other devices, refer to its documentation for the API function list.
