Hello gurus in the house. Please I am in a real fix.. I have to submit a project on Monday, but I am having issues with it.

Basically, I am required to carry out a PROTEUS simulation involving multiplexing using Pic 16f877, whereby (1) A keypad and a LCD display will be connected on the same port, say PORT D, though the EN and RS will be on PORT A

(2) A keypad and a Seven Segment Display, still using the same PORT D..

Can anyone please help with the basics of this multiplexing.. I can do the simulation using separate PORTS, but not the multiplexing .

Gracias

What compiler are you using?
If it is ccs c, search there forum for flex lcd driver and flex keypad driver.
With these drivers you can connect them as you like.

@ www.ccsinfo.com/forum

...and don't forget to get them from our store. We also have I2C LCD driver module which will help you to drive you lcd with only 2 pins.

Why not try CCS C because it has enough online resources

even me will like to know them because I have been searching for them since. But I am thinking of something difference, may be I will save money and get a good 3d printer. It will do a lot of plastic works.

This is my own crude method of managing pin space and multiplexing input with output.
I used the EN of d lcd to enable the lcd while d kp_en to enable d keypad. So the keypad and d lcd share time resources i.e. the time allocated for lcd screen refresh is shared and allocated to read keypad state.

At the start of the subroutine for lcd_write, you will turn portD direction into Output and at kp_read u turn the port into input port.

Enjoy the circuit and feel free to ask questions and dont mind my handwriting and handdrawing.

Thank yo so much.
As a matter of fact as at when I was typing I have already studied the pcb wizard 3.5 software and I have to say it's so easy to use and I have already designed small circuit with their PCB layout.
Did not think it would be this easy. Loving the software.
I have Proteus 8.1 full cracked version but Ares is somewhat complicated.
PCB wizard rocks..
One more thing.
which do you guys prefer auto routing or manual routing?
First of all, I'm in love with this thread. Big thumbs up to everyone. Quite sad that the frequency of contributions has greatly reduced recently.
In my own case, I only know how to use Proteus Ares for PCB design. Yet to try out PCB wizard or PCB artist. Maybe it was quite tough at the start when I was learning it but once I got the hang of Ares, I started to enjoy using it.
One sensitive area though is the aspect of choosing packages for your components in your design as you have to ensure it will be compatible with the components in your physical design. For example, I once had a project in which involved some relays. The package I chose for the relay in Ares had the NO pin at the left side while NC pin was at the right but the actual relay to be used had the pins arranged in the reverse order (needless to say I only got to find this out after already etching and drilling the board). That almost spoilt the whole work I was doing if not for some improvising I did to go round the problem.
Looking forward to learning much more here.

I know I'm quite late for the party now,
But hello Gurus in the house,
I humbly greet every one oo.

To those that build different modules of pcb and likes.

I would like to ask some question troubling me.

How do one properly troubleshoot a short in a circuit?

I understand with continuity test, one could troubleshoot for an open circuit.

But for a component that has been shorted in a circuit, I do one diagnosis such circuit.

NB: no schematics

Thanks in advance!

Re: Electronics Circuit Design From Concept To Implementation by Yemmyteespeed007(m): 5:22pm On Jun 17, 2017
a short in your circuit must have occurred mostly because of a damaged component in the circuit, you have to be able to tell where it is happening so that you can use your meter to test the components around that area with continuity function.

i hope that helps.

Nice Attempt. Especially as you've crossed the "want to do it stage" to the "done it stage".
As time passes, you should work with a laser printer, magazine(or toner transfer) paper, and circuit design software such as EagleCAD to neaten your work and improve efficiency. Kudos

Hello house,

Does somebody knows where I can get active and passive electronic components in Ibadan.

Or any shop/office in Lagos/Ogun that I can always order from.

Thanks
