Hi this is augus here
I had done a keypad circuit by using 74ls148 Encoder Ics ..total 16 keys.. i have used 2 encoders to take the data from keypad and the o/p of two encoders is given to nand gate so i will get o/p values from nand gate as 0001 to FFFF. ...Now Each key is having 4 chars.....how to write a code to analyase which key is pressed and which valve to be taken ...time delay etc.
