Abstract

Numbers and characters displayed on electronic devices use modules of seven LEDs with an eighth LED for the decimal point. Conventions for labelling the LEDs are a, b, … g or A, B, … G, with the decimal point denoted P or DP. There are 10 pins on the 7-segment display with pins 1 to 5 corresponding to LEDs e, d, common, c, and P with pins 6 to 10 mapping to LEDs b, a, common, f, and g. The two common pins, 3 and 8, are connected to a common cathode or common anode (see Figure 5-1).
