#63217 - Mobile Keypad2 Responding to: ???'s previous message |
first i am using 74c922 with 8052...and i made a code to isplay the pressed number on LCD...by using interupt
As when you press a key,the 8052 will get int(p3.2) and then get the pressed number(as ASCII in 1 location) but what i want is make it like mobile keypad,but i don't know how to compare the two pressed number befor display it on LCD thanks for help |
