Thanks guys am already on it, if i get stuck i will holla back.
Best regards.

OK. As always, loads of ways, assuming you have your keypad working. Here's a starter for ten:-

Create const character string "PASSWORD".
Create character string array input_buffer
--- ...

What can't you do?

(1) Read the keypad.
(2) Handle the keypad data.
(3) Deal with user interaction.

Please be more specific.

what i want is for a user to enter a password, then the pa ...

Hi everyone!
Please how do i request an input that will be displayed on a 16x2 lcd from a user(assuming i already designed they key pad), and then store the input. I am able to send messages to the s ...

Simplest 'trick' is to create a 15 wide diode OR gate connected to RB0. .

But I still say it's easier to do an external Wire-OR circuit with diodes.

There are some tricks you can do with the
hardware peripherals to emulate an edge triggered interrupt pin, but
I don't know if you want to do that. It would be better, I think, if you
used an ...

Hi, everyone, I am working on a project that uses interrupts. The program flow is such that MCU sleeps when interrupt is triggered, then by making pin_b0 low, it wakes up. It works fine at this stage, ...

Hi,

Until you've got the basic communications working between your boards, your code is way too complicated! On the transmit side, just send a single character repeatedly with a short delay betwe ...

the RX return side is at 3v levels - may not reliably toggle the receive side
pins on each pic
you are right, i checked the voltages at the various pins with a multimeter and these are the outcome: ...

you are most likely tangled up in 3v/5v non level translated misery IMHO
Thanks for your response, please can you explain what you meant by that,this is the connection i used:

Hi everyone, I am working on a project that requires wireless communication between two PIC's. I tested a simple program on the PIC's using hardware UART (wired) and its working clock is 20MHz wheneve ...

Your main crystal oscillator is not running.

When you select 'HS', the code therefore does not run.

It works with the fuses you post, but at a silly speed, because 'FCMEN', is enabled. This is t ...

This code causes the LED to be on for 500ms then off for 500ms = 1 cycle per second or 1HZ

To try the 20MHZ crystal, change INTRC_IO to HS and connect your
crystal. Make sure to keep the connect ...

Try a simpler program. This has been confirmed to work on the
internal oscillator and blinks the LED at 1HZ. Note that I moved the
LED to Pin C1 to avoid other peripherals and keep the program sim ...

ahhh.....when you 'built(F10)' the program was the 'build option' set to release or the default of 'debug' ?
how do you mean, please expatiate. i used the "Build All", (F9) option on the '' ...
