This is my first time programming low level language microprocessors, I have experience with Arduino bu this looks pretty difficult for me. Not ridiculous at all. The Microchip XC8 C compiler is a separate download from http: Forums Posts Latest Posts.

Sorry for such questions, that might seem you ridiculous. On power-up this code should be If you are using a crystal or external oscillator that’s quite easy. Exefcices breakpoints automatically disabled 16F88 cannot set internal oscillator frequency beyond Another question, how can i read the keypad letter by letter?

The code could also change the lock password by pressing another exsrcices of digits. Otherwise, break the problem down into sections. 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. Isn’t included in de mplabx, the compiler?


It specifies the safe shall re-lock after five seconds. Exrecices example, the key sequence: This is indicated by a letter L on the display. It is not for the same MCU but is is baseline code.

exedcices Remember banksel is your friend. User Control Panel Log out. The handicap i see is how to be always listening if a key is pressed typing the password without an interrupt? Although it could be done with external logic, 1f84 multiplexing, its a clear indication you should use a PIC with more pins.

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. Posting images, links and code – workaround for restrictions. Why does my PIC32 run slower than expected?

Thanks for pointing this out. Ismael 1 7 Replies Related Threads. 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. Sorry fat fingers ipc a keyboard. Haven’t received registration validation E-mail? 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. See the data sheet pages 11 and Any advice will be truly appreciated!

Thank you in advance. For any method of implementing the delay, the first thing you need to know is Fosc.

Exsrcices use interrupts unless its a project requirement, as it makes it quite a bit tougher to get right. The following describes how the lock should work: Then you have toi strt stringing all together. This document has a very long asm file included that you can use for a reference. B you will need a version of the 5 second delay that exits if any key is pressed.

It does not specify what event starts the 5 second period. If you know some webpage with examples it will be helpful too. Forum Themes Elegant Mobile. When you say XC8C compiler what do you mean?

Essentials Only Full Version. I also support http: The code should then be input twice consecutively for the usercode to assume the new value.

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.
