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, 16ff84 you only need to use if you require background timekeeping e. Remember banksel is your friend. It is not for the same MCU but is is baseline code.

M Super Member Total Posts: Although it could be done with external logic, or multiplexing, its a clear indication you should use a PIC with more pins. It specifies the safe shall re-lock after five seconds. The Microchip XC8 C compiler is a separate download from http: Sorry fat fingers on a keyboard.

Start with that 5 second delay. Forum Themes Elegant Mobile. Then you have toi strt stringing all together. Ismael 1 7 Replies Related Threads.

Essentials Only Full Version. Sorry for such questions, that might seem you ridiculous.

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 exercjces parts you adviced me.

See the data sheet pages exerciced and Another question, how can i read the keypad letter by letter? The problem definition you posted is ambiguous.

Exercice corrigé

Posting images, links and code – workaround for restrictions. If the code is correct, the safe unlocks, indicated by a letter U or u on the display. Thank you in advance. It does not specify what event starts the 5 second period. On power-up this code should be The code could also change the lock password by pressing another sequence of digits. I want to do it by interruptions but sincerely I don’t know how? Otherwise, break the problem down into sections.

This is indicated by a letter L on the display. Not ridiculous at all.

B you will need a version of the 5 second delay that exits if any key is pressed. Don’t use interrupts unless exercies a project requirement, as it makes it quite a bit tougher to get right.

les microcontroleurs (PIC 16F84): Participants

This document has a very long asm file included that you can use for a reference. Any advice will be truly appreciated! For example, the key sequence: User Control Panel Log out. If you are using a crystal or external oscillator that’s quite easy. The code should then be input twice consecutively for the usercode exercoces assume the new value. Thanks for pointing this out. I also support http: When you say XC8C compiler what exerckces you mean?

PIC16F84 – DIGITAL LOCK PROGRAMMING MPLABX – KEYPAD AND 7-SEGMENT

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

Debug breakpoints automatically disabled 16F88 cannot set internal oscillator frequency beyond 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.

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. For any method of implementing the delay, the first thing you need to know is Fosc. Why does my PIC32 run slower than expected?
