Hello Darrel,

Thank you for the tip. I did realize the short circuit situation and added series resistors in line with the row bits.

However, your tip is better because I can eliminate those...

Grandpa,

Here is the the link of which you speak of.

Its mostly all over my head at this point. But I am learning fast. I book marked it and post it here for others refrence.

Hello all,

What an adventure this has been! I have completely fallen for this enbedded coding stuff and in paticular PBP. Best money I have spent in a long time. More fun then I have had in a...

I just spent the last...oh....hour or so reading this "Train Wreck" of a thread.

All I gots to say is this:

Thanks Adam,

I appreciate your kind words of encouragement.

I just kinda felt like a dumb A** if you know what I mean. I feel like a leach around here most of the time because I am still very...

Feels like I am at the Church of the Blessed PIC!

Ok so here is a prime example of why you should read the entire section of the commmand.

I glazed over it to get to the defines section so I...

Man I learn alot reading this forum!

Where is the above mentioned "$8D" command documented? I had no idea you could do that? I knew you could shift right or left but did not know you could "jump"...

oops....Sorry....it was late when I posted that. I think I was going for the four(4) key on the keypad and fat fingered it to the one(1) right below it.

OK...

The snuber I spoke of actually is acrossed the "contacts" of the relay. You only need this if your driving an inductive load or a really high current circuit. Like say a large motor or...

Ok here is the deal,


You MUST use a diode across the coil of ANY relay (unless its got one built in) Its for the back EMF (colapsing magnetic field) of the coil when you un-energize it.

If...

Hello Mister_E,

First let me kiss a little butt. I have been reading alot here and frankly..."You the man!"

Second, and I know this would be alot to ask. But concerning your Keypad.bas include....

"PortB.0 <-- zero after PortB indicates you're dealing with a bit.

PortB.0[X] <-- [X] = the bit index pointer."


Thanks bruce that is a brilliant little tidbit of information (for a noob like...

Thanks everyone...

These are some really good idea's. I had to "walk away" for awhile. I will read Melanie's post(man she is a wealth of knowledge....Bet she was born with a PBP manual in her...

Hello all,

Just to keep things simple and not going into alot of details here is my question:

Can you use a variable in the port settings?

Example....

main:
for I = 0 to 7

I think this is the first time I have seen this kind of behavior here.
(or maybe I am just confussed? Would not be the first time!)

I did not think it existed on this forum. But I guess I was...

Hello all,

I have to ask because I have NEVER seen it done any other way. But is it not just plain good design practice to current limit with series resistors and pull up or down ALL digital...

I feel so at home here.

OK everyone here is what I did.

I ordered my upgrade and manual for PBP (Should be here anyday)

I went with the Microe EasyPic4 with a few of the proto board adapters.

I cant tell you how nice it is to get some good help as a noob on a forum. It is RARE! I read a sticky from Melanie about this and it must have worked!

I do appreciate all the suggestion on chips....

Thank you all for the input on the class. Maybe its a good thing I did not go. (the world may never know!)

But what about a good solid chip to start with. Do they make one with a built in RS-232?...

If you have the expertise to do it...I would talk about a cherry gig! I got the 900 figure from them. They said it includes a dev board, compiler, editor a hand full of PIC's adapters, programers,...

Yea its expensive, But if you look you end up with about 900 bucks worth of stuff dev boards, the pro compiler etc...so I figured it was really only about 1000 bucks. I have NOT taken the class but...
