Hi guys , i have a question .
i want to make 5 rows 6 columns keypad and assign to each button a binary sequence say if button 0 is pressed a binary sequence of 10101010 appears at 8leds array using pic16f877a ,and so on ( 30 keys so 30 binary sequence )
5*6 keypad gives 11 input pins , but flowcode limit the keypad to max of 4*4 , i tried making 2 keypads 4*4 which will give me 16 input pins which is OK , but i cant make it work , how to do this and how to assign the values to the keypad keys .
in practical I'm making this keypad using simple dip-switches connected like keypad ( matrix ) , thank you in advance .
