Patent number: 9210769Abstract: A light emitting diode (LED) is driven with a plurality of pulses having controllable pulse widths and positions within clock time periods that provide for both LED light intensity control and digital information communications from a single output node of an integrated circuit (IC) device. The LED light intensity is determined by the duty cycle of the pulses where the human eye integrates these light pulses from the LED into continuous light intensity levels. The digital information contained in the light output from the LED is detected by a photo-detector that converts the light pulses into electric signals that are demodulated and read by a circuit debugger and/or manufacturing test station. The aforementioned operations allow continuous visual display and data transmission using only one output node of the IC device. This is especially advantageous when using low pin count IC devices.Type: GrantFiled: March 15, 2013Date of Patent: December 8, 2015Assignee: MICROCHIP TECHNOLOGY INCORPORATEDInventors: Joseph Julicher, Jerrold S.
