A very simple project with PIC micro PIC16F628A (only ONE component plus the battery). The circuit purpose is to show a scrolling text on oscilloscope. The characters to be displayed can be stored by user in EEPROM (ascii codes from 0×20 to 0×5f so numbers, capital letters and special characters are available). The first Eeprom location with 0xFF value is considered as end of text. The last Eeprom location (addr 0×7F) contains the scrolling speed in 20mS steps. The oscilloscope will be set for timebase=2mS/div and Y-ampl=1V/div
