COMPUTER ERROR CHECKING METHOD BY USING LCD/LED

摘要

An error checking circuit comprises an input/output decoding processor (20) and an interrupt processing processor (30) which are connected with CPU (10). The input/output decoding processor also connected with a real time clock (60), a power converting circuit (80), a crystal oscillator (90) and a battery (85). The interrupt processing processor is connected with an interval timer (70) and a crystal oscillator (95). The LCD/LED display device (50) connected with a LCD/LED drive circuit (40) visually displays the true or false state of the computer hardware.
