    Layout what am I doing wrong?

    Thank you, very very much. Sort of one of those things you just don't want to be true, but it is. Will check it out today. Just needed to talk it out with someone else. Wife said she didn't have a clue as to what I was talking about. I have done that with smaller parts but told myself couldn't...

    Seeking advice on fixing an old amplifier which is working but not entirely.

    I cut my teeth repairing things like this. Don't know what all the unit has one it but I would gently clean any switches it may have, if possible and the headphone jack would need it also. If the jack is wired so as to cut the speaker out when a headphone is plugged in.... Could tell you more if...

    Layout what am I doing wrong?

    Greetings ! I am making a single sided PCB, using Eagle 6.2. And using the transfer method of etching. I have made them before and have never had this problem. When I print (laser print) I "mirror" image, all black, print it and have almost etched it when I discover the Arduino pins are on the...

    [SOLVED] HELP!! Still Learning, Changing RA0-RA3 to outputs.

    Yes, I had ordered some transistors to handle additional current but what I totally missed was the total current limit of the micro. Just forgot to consider it, actually assumed it would be ok. I know, that's bad when designing things thanks for the reminder. I was online a while ago, after...

    12000 mAh li-ion rechargeable battery?

    Hi! I am not an expert, by any means. But I havn't seen that on a battery anywhere, unless you build one. Looks like you may be on to something. Another project time????

    [SOLVED] HELP!! Still Learning, Changing RA0-RA3 to outputs.

    Woops!!!!!!!! Thanks for the info....I mean REALLY Thanks. Guess we can say the PK3 can do more than 30 ma. Well more than 30ma. I might say. Wouldn't want to burn it up tho.....so hard to explain why I have only used it a few days and sent it up in smoke. I wasn't running the LED's them hard ...

    [SOLVED] HELP!! Still Learning, Changing RA0-RA3 to outputs.

    Hi, My first project was just to control some LED's. Actually the 5050 tri-color led, which is one reason I needed all the ports. Personally, I just want to learn everything I can. I have got board etching down pat, now working on the programming. I'll attach a photo, you might as well see the...

    [SOLVED] HELP!! Still Learning, Changing RA0-RA3 to outputs.

    Ok, I loaded the PGM given by wp100. He's right, HEX works fine. (It looked so nice blinking) I spent the next two days studying "inline assembly" with the hope I could just add the assembly and go on. (with permission from wp100, of course) No such luck:-( So Friday, I went back to C, in...

    [SOLVED] HELP!! Still Learning, Changing RA0-RA3 to outputs.

    Incredible, Works fine with assembly. Thanks so much for your work. Everyone has been so kind on this forum. I did a-lot of reading yesterday and last night, including data sheet :grin:, and all deserve a reply for their help. But for now, I'll go make a pot of coffee and rethink everything...

    [SOLVED] HELP!! Still Learning, Changing RA0-RA3 to outputs.

    Hi! Thanks for the info an reply. I made the changes, same problem. Meanwhile I have been looking in all my books for info. We'll figure it out. I was wondering how to change the ANSEL bits and you provided that solution. Much thanks I'll def. reply with my results so we can all learn. David

    [SOLVED] HELP!! Still Learning, Changing RA0-RA3 to outputs.

    Wow!! Thanks for the reply, I'm at my wits end. I've been on the web all day and have tried the ANSEL register. Probably incorrectly but commented out those lines in code. I will look at those sites, Thanks. I have years ago written in assembly, for windows but havn't gotten around to it with...

    [SOLVED] HELP!! Still Learning, Changing RA0-RA3 to outputs.

    Just joined the forum, need some help. I am using MPLAB 8, C18, and learning to program. I am using a PIC18F45K20 ic. My code is a little messed up in that I have been trying different things found on the web. I have gone through the Data sheet and it is confusing when attempting to see what...
