    Till date I have implemented the things. Reading keypad, storing into array and then comparing the two array. Now I want to store this array data, that is password in EEPROM of PIC16F886, since this controller has 256 byte of EEPROM built in. I read CCS C help files and other code. I have some...

    alexan sir thanks for giving me link for how to shorten the if loop. And as you said it uses less resources. So I will use that one only but for get familiar with another method I will experiment with string function also as said by arunsharma0731.

    Alexan sir, the function you suggested is working fine. In next stage I want to implement number of wrong password entry and time out. When three time wrong password enter happen then it goes in locked state and require master password. And during password entry a some second of time is set, if...
