Next I’d write the 7 segment display routine, and extend it to display digits so you exerccies use it to check the keypad routine when you write it. Start with that 5 second delay. Sorry for such questions, that might seem you ridiculous. Thanks for pointing this out. Why does my PIC32 run slower than expected?

This is indicated by a letter L on the display.

Don’t use interrupts unless its a project requirement, as it makes it quite a bit tougher to get right. For any method of implementing the delay, the first thing you need to know is Fosc. Debug breakpoints automatically disabled 16F88 cannot set internal oscillator frequency beyond See the data sheet pages 11 and Then you have toi strt stringing all together.

Ismael 1 7 Replies Related Threads. When you say XC8C compiler what do you mean? Although it could be done exefcices external logic, or multiplexing, its a clear indication you should use a PIC with more pins.

Essentials Only Full Version. Thank you in advance. Not ridiculous at all. Any advice will be truly appreciated! Otherwise, break the problem down into sections.

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. The code could also change the lock password by pressing another sequence of digits. The problem definition you posted is ambiguous. User Control Panel Log out. The code should then be input twice consecutively for the usercode to assume the new value.

The following describes how the lock should work: Remember banksel is your friend. If the code is correct, the safe unlocks, indicated by a letter U or u on the display. For example, the key exrcices PIC16 IOC pi 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 esercices to use if you require background timekeeping e.

On power-up this code should be Another question, how can i read the keypad letter by letter? Posting images, links and code – workaround for restrictions. Forum Themes Elegant Mobile. My idea is as you said too: Forums Posts Latest Posts.

B you will need a version of the 5 second delay that exits if any key is pressed. 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 specifies the safe shall re-lock after five seconds.

Les interruptions Pic – Safi: CPGE – EST – ENSAS – BTS – OFPPT – ITSA

The Microchip XC8 C compiler is a separate download from http: 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. It is not for the same MCU but exercice is baseline code.

Isn’t included in de mplabx, the compiler? If you know some webpage with examples it will be helpful too. Sorry fat fingers on a keyboard. This document has a very long asm file included that you can use for a reference. I also support http: M Super Member Total Posts: The handicap i see is how to be always listening if a key is pressed typing the password without an interrupt?

This is my first time programming low level language microprocessors, I have experience with Arduino bu this looks pretty difficult for me.

If you are using a crystal or external oscillator that’s quite easy. I want to do it by interruptions but sincerely I don’t know how? It does not specify what event starts the 5 exercuces period.
