Scrolling text on Oscilloscope



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 0x20 to 0x5f 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 0x7F) contains the scrolling speed in 20mS steps. The oscilloscope will be set for timebase=2mS/div and Y-ampl=1V/div
