Don’t use interrupts unless its a project requirement, as it makes it quite a bit tougher to get right. Essentials Only Full Version. The problem definition you posted is ambiguous.

I also support http: This is my first time programming low level language microprocessors, I have experience with Arduino bu this looks pretty difficult for me. The Microchip XC8 C compiler is a separate download from http: Forum Themes Elegant Mobile. I want to do it by interruptions but sincerely I don’t know how? It specifies the safe shall re-lock after five seconds. The handicap i see is how to be always listening if a key is pressed typing the password pci an interrupt?

For any method of implementing the delay, the first thing you need to know is Fosc. Although it could be done with external logic, or multiplexing, its a clear indication you should use a PIC with more pins. If you know some webpage with examples it will be helpful too. 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. If you are using ecercices crystal or external oscillator that’s quite easy.


It is not for the same MCU but is is baseline code. Start with that 5 second delay. Not ridiculous at all.

When you say XC8C compiler what do you mean? Forums Posts Latest Posts. If the code is correct, the safe unlocks, indicated by a letter U or u on the display. Thank you in advance. 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.

Then you have toi strt stringing all together. Sorry fat fingers on a keyboard. Haven’t received registration validation E-mail? 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 presses would meet the specification.

This document has a very long asm file exercicse that you can use for a reference.

It does not specify what event starts the 5 second period. B you will need a version of the 5 second delay that exits if any key is pressed. See the data sheet pages 11 and Another question, how can i read the keypad letter by letter? On power-up this code should be Sorry for such questions, that might seem you ridiculous.


The following describes how the lock should work: This is indicated by a letter L on the display. 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. The code could also change the lock password by pressing another sequence of digits. Thanks for pointing this out.

Any advice will be truly appreciated! User Control Panel Log out. Remember banksel is your friend. For example, the key sequence: PIC16 IOC is buggy and is only recommended for wakeup from sleep, and the only other interrupts on an ‘F84 are the external INT pin, which wont help you much and the Timer 0 overflow interrupt, that you only need to use if you require background timekeeping e.

Why does my PIC32 run slower than expected?
