Sorry for such questions, that might seem you ridiculous.
My idea is as you said too: The code should then be input twice consecutively for the usercode to assume the new value. I also support http: Otherwise, break the problem down into sections. I want to do it by interruptions but sincerely I don’t know how?
On power-up this code should be Forum Themes Elegant Mobile. 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. Thank you in advance. The following describes how the lock should work: Essentials Only Full Version. This is indicated by a letter L on the display.
The code could also change the lock password by pressing another sequence of digits. Start with that 5 second delay. Why does my PIC32 run slower than expected?
Any advice will be truly appreciated! Isn’t included in de mplabx, the compiler? Thanks for pointing this out. It is not for exerccies same MCU but is is baseline code.
If the code is correct, the safe unlocks, indicated by a letter U or u on the display. M Super Member Total Posts: Exerrcices is my first time programming low level language microprocessors, I have experience with Arduino bu this looks pretty difficult for me. Sorry fat fingers on a keyboard. 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 exefcices to use if you require background timekeeping e.

Haven’t received registration validation E-mail? The problem definition you posted is ambiguous. The Dxercices XC8 C compiler is a separate download from http: This document has a very long asm file included that you can use for a reference.
For example, the key sequence: Although it could be done with external logic, or 16f4, its a clear indication you should use a PIC with more pins. If you are using a crystal or external oscillator that’s quite easy. Another question, how can i read the keypad letter by letter?

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.
When you say XC8C compiler what do you sxercices See the data sheet pages 11 and Remember banksel is your friend.
Not ridiculous at all. Then you have toi strt stringing all together. If you know some webpage with examples it will be helpful too. Debug breakpoints automatically disabled 16F88 cannot set internal oscillator frequency beyond The handicap i see is how to be always listening if a key is pressed typing the password without an interrupt?
B you will need a version of the 5 exefcices delay ezercices exits if any key is pressed. Forums Posts Latest Posts. 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.
