AN2252: LED Digit Displays - Large Quantities

PSoC ICs are capable of handling a large variety of analog and digital signals. But how can we see those large quantities of processed information on standalone projects that need to be readable from a distance? LED displays are a good solution. This Application Note presents a simple LED solution with a large display for 16 characters, 14 segments plus decimal point and a 16-segment bar graph. It utilizes only seven MCU I/O pins. This solution can be easily extended to handle additional LED digit groups by adding a single data output per group. Also, it is possible to manage larger digit quantities if seven segment displays are used.
