The Microchip XC8 C compiler exercicez a separate download from http: The handicap i see is how to be always listening if a key is pressed typing the password without an interrupt? This document has a very long asm file included that you can use for a reference. M Super Member Total Posts: Don’t use interrupts unless its a exervices requirement, as it makes it quite a bit tougher to get right. Forums Posts Latest Posts. Otherwise, break the problem down into sections.

If the code is correct, the safe unlocks, indicated by a letter U or u on the display.

Thanks for pointing this out. Haven’t received exwrcices validation E-mail? Debug breakpoints automatically disabled 16F88 cannot set internal oscillator frequency beyond Start with that 5 second delay. Forum Themes Elegant Mobile. Isn’t included in de mplabx, the compiler?

It is not for the same MCU but is is baseline code. It specifies the safe shall re-lock after five seconds. The code could also change the lock password by pressing another sequence of digits. Anyway, do you have any practical manual so i can get started with function in asm and start implementing the program in the different parts you adviced me.

Essentials Only Full Version. The code should then be input twice exercicess for the usercode to assume the new value. Posting images, links and code – workaround for restrictions. When you say XC8C compiler what do you mean? I also support http: See the data sheet pages 11 1684 If you know some webpage exercice examples it will be helpful too.

Although it could be done with external logic, or multiplexing, its a clear indication you should use a PIC with more pins. Ismael 1 7 Replies Related Threads.

On power-up this code should be User Control Panel Log out. My idea is as you said too: B you will need a version of the 5 second delay esercices exits if any key is pressed.

For example, the key sequence: Sorry for such questions, that might seem you ridiculous.

I want to do it by interruptions but sincerely I don’t know how? It does not specify what event starts the 5 second period. Thank you in advance. Another question, how can i read the keypad letter by letter?

Then you have toi strt stringing all together. Next I’d write the 7 segment display routine, and extend it to display digits so you can use it to check the keypad routine when you write it.

Not ridiculous at all. Sorry fat fingers on a keyboard. This is my first time programming low level language microprocessors, I have experience with Arduino bu this looks pretty difficult for me. Remember banksel is your friend. For any method of implementing xeercices delay, the first thing you need to know is Fosc.

However if you want to implement a background timer using a Timer 0 ISR, in the hope of getting extra credit, we can certainly help you. It also doesn’t specify any actions triggered by a key press while the safe is unlocked, so even a simple 5 second delay that didn’t check for key exercicee would meet the specification.

The following describes how the lock should work:
