MAX7219 8-Digit 7-Segment Digital LED Display Overview:
This 8-digit red LED numeric display is driven by the MAX7219, using an SPI interface requiring three I/Os. The MAX7219 is an integrated serial input/output common-cathode driver, between the LEDs and the microcontroller. Only one external register is used to set the current of each LED segment.
This device was added to Parallax inventory as a quick demonstration to the sample code for the Propeller 2 SPIN/PASM SPI Driver used in the Propeller 2 Live Forum. It is compatible with all Parallax microcontrollers, to provide simple visual feedback for numbers and data.
