Why does my PIC32 run slower than expected? 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.

Don’t use interrupts unless its a project requirement, as it makes it quite a bit tougher to get right. The handicap i see is how to be always listening if a key is pressed typing the password without an interrupt?

On power-up this code should be My idea is as you said too: 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.

The code should then be input twice consecutively for the usercode to assume the new value. Forum Themes Elegant Mobile. M Super Member Total Posts: Debug breakpoints automatically disabled 16F88 cannot set internal oscillator frequency beyond Thank you in advance. Another question, how can i read ezercices keypad letter by letter?

Although it could be done with external logic, or multiplexing, its a clear indication you should use a PIC with more pins.

Then you have toi strt stringing all together. For example, the key sequence: B you will need a version of the 5 second delay that exits if any key is pressed.

Essentials Only Full Version. Posting images, links and code – workaround for restrictions.

If you know some webpage with examples it will be helpful too. If the code is correct, the safe unlocks, indicated by a letter U or u on the display. See the data sheet pages 11 and 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. Thanks for pointing this out.

Otherwise, break the problem down into sections. The following describes how the lock should work: Forums Posts Latest Posts. The problem definition you posted is ambiguous. Not ridiculous at all. I also support http: 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.

Any advice will be truly appreciated!
