Abstract:
1. A system for testing a light emitting diode (LED) and a connector thereof, the system comprising: a chip having general purpose input output (GPIO) function for outputting potentials to the LED via a plurality of pins; a test fixture connected with the LED, for receiving data output from the LED after the chip outputs the potentials to the LED; a parallel interface connected with the LED through the test fixture, for receiving corresponding data output from the test fixture; and a programmable device connected to the chip and the parallel interface, the programmable device comprising: a setting module for predefining ideal data before the chip outputs the potentials to the LED; a pin initializing module for initializing the pins of the chip to a potential output mode; a potential controlling module for controlling the chip to output different potentials to the LED; a data capturing module for capturing the data from the test fixture to the parallel interface; and a comparing module for comparing the captured data with the ideal data, and judging whether the two data are equal.
