A3 on the scheme i uploaded is not connect RA0 --> A1 ; RA1 -->B1 ; RA2--> Enable, however RA3 I connect with Demultiplexer's VDD.
So if i want to keep that demultiplexer if I put diodes on ...

Every SW presents one digit of the key combination. SW1 presents first digit, sw 2 second and so on.
On each SW only one switch is enabled, i.e SW1 - 9 is ON SW 2 - 4 ON, SW3 - 5 ON, SW4, 1 ON

So ...

If you turn the enable pin HIGH, than you have on the Outputs High state, that means on PORTB pins you will receive HIGH state and you can/will mess up the keypad things.
PIN A3 is connected to the p ...

I'm trying to make KeyCode door with key that is chosen manually with DIP-Switches - 9.
Here is the scheme of my project:

Thank you very much!

The idea is if I'm using shift register, like 74hc4049 using D input of shift register for input 0 or 1 and clock input for the new bit... i want to collect whole byte before I enable the Strobe, so ...

Well, i have a question that i can't figure out... I have an 8bit integer for example:
int8 a = 10;
i want that integer to transfer to a PIN_B7 using output function bit by bit
So if my integer a i ...

Sorry for the double post, but i want to be sure you will read it.
So i put 150 ohms resistor on the pic outputs and everything works, even with my suggested code.
Thank you a lot guys, i even ask ...

Yes, of course i will finish it. And thank you again. Well maybe the missing resistors is the problem, because i tried your code just to see will it process the code correct, so i have to put my input ...

Ttelmah, thank you for the code you wrote, i will try it later, cause i have to go out. I do not use any resistors to led indicator, because it's consumption is big enough, with two resistors 330 ohm ...

Hello, guys. I'm new in programming PICs, so i am stucked on my new project. The main idea is to make program, that shuffles 2 numbers. So that two numbers i'm trying to display on 2 digits 7 segment ...
