This module is ideally suited to adding a 2 line 4 digit red 7 segment display to your project. This module lets you display your information in a bold and bright way, writing all manners of numbers and words with numbers from 0-9, A-F, - and . .
The module is designed for use on its own or combined with other modules to create larger displays. This module has Red LEDS that are powered via a serial connection to a microcontroller.
Particular characters are generated by taking a two digit Hex value then using an AND function with 0x80. Using the newly created Hex value you drive the CP pin LOW, send the data on the DAT pin and then set CP to HIGH. This of course needs to be performed quickly for persistence of vision (appear constant) to kick in.
