Landing Pad Project (modding the LED sequencer)

[Colonel Shofer]

TY.

Just need to say, I only had one LED out, as per your schematic, in the simulation, but that should not affect this stage, should it?

I am a novice, on PICs, in these sims.

It looks like a case sensitivity issue ... but you must use MPLAB to compile and prog the chip, no?

It is case sensitivity

look at http://pcbheaven.com/picpages/MPLAB-Starting_a_new_project/


Item 10 - disable case sensitivity in MPLAB

Step 10:
The "Buld options" dialog appears. Go to the tab labeled "MPASM Assembler" and make sure the checkbox "Disable case sensitivity" is checked. Then, click "Ok"

Cheers

[Colonel Shofer]

Great George TY, worked in MPLAB.

Now, see if I can find how to do that in ISIS !!!  ideas?

Cannot even get ISIS to see the .hex file from MPLAB yet, even though it is pointed at it !!!

Cheers.

CS

[Colonel Shofer]

OK, got the pic going in ISIS, with the .hex from MPLAB

Anyone ready to help me with the program for my LED layout, please?

TYIA.

CS

[kam]

do you have a preliminary schematic in mind? like, for example, how the LEDs are supposed to light?

[Colonel Shofer]

Hi K,

Yup, just on it now, TY

CS

[Colonel Shofer]

TY K,

OK, here is 'the spec' ...

(1) 4 'rings' of LEDS, each in parallel, for now, but will be optimising later.
(2) 1 blue ring, PWM (?) to pulsate.
(3) 3 red rings, Outer (O), Middle (M) and Inner (I).
(4) Sequence is O>M>I>O>M>I>O>M>I etc
(5) I will be running each ring, from a transistor, in reality.

My main problem (because I am a PICs programming newbie ), is how to get the blue ring pulsing, continuously, whilst the red rings sequence down from O to I.

Please excuse cludgy wiring





TYIA.

CS

[kam]

is there any particular reason to use PIC? The circuit that you describe needs only a 4017 and a 555 (oh, and 4 transistors). See the attachment.

P.S. The 555 must be connected as an astable multivibator but i was too lazy to do it on the schematic. It is easy to do it. LEDs13 through 16 are the blue LEDs, and the others are the 4 LEDs on each "circle".

[Colonel Shofer]

Hi K,

No, that is great TY ... a wonderful alternative which I will build too

How would I get the blues to pulsate (like this, I guess ... http://digiassn.blogspot.com/2009/03/electronics-pulsingbreathing-led.html ... another 555 )?

The reason for PIC. is to learn how to prog and use PICS

Also, I do envisage more circuity connected to it, with different timings (and none) ... that is why I want to learn how to separately-control blue versus red, at different timings, turn on/off/pulsate independently, within PIC etc.

Even just a small example, with two reds and one blue LED (at different frequencies/on/off/pulsate) would be great, if you do not fancy the whole prog

Again, great, TY.

CS

[Colonel Shofer]

Post above modified.

CS

[kam]

yeap, you will need another 555.

as for the PIC, you can have 3 different pulsing rates like this:

Code: [Select]

MainLoop
 bsf Porta,0
 call Wait500mSec
 bsf Porta,1
 call Wait300mSec
 bsf Porta,2
 call Wait200mSec
 bcf Porta,0
 call Wait500mSec
 bcf Porta,1
 call Wait500mSec
 bcf Porta,2
 call Wait500mSec
 goto MainLoop
You will notice that you need 2 delay subroutines, one for 500mSec, one for 300 and one for 200. Either make them yourself, or download the "msecdelay16Mhz.inc" from one of my PIC projects.

[Colonel Shofer]

Hi K,

The problem with the 555 circuits, that I can find, is that they only drive one pulsating LED, so until I can sort out PWM, via the PIC (lots for the Arduino !!! ), I will have to settle for flashing blues.

TY for the code, I will try and get my head around it and get a simulation going.

Cheers.

CS

[kam]

let me get this straight. you want pulsing or breathing? I mean, you want the leds to turn on-off, or to fade-in fade-out? Why you mention the PWM?

[Colonel Shofer]

Hi K,

Sorry, to me ...

(A) pulsating = pulsing = breathing,
(B) flashing = on/off.

PWM is the technique used for (A), in the Arduino community, and I would like to learn how to implement it in the PIC domain (I have not seen it done) and with 4 blue LEDS !!!.

Cheers.
