    Getting value of ADRESH out of a pic μcu?

    Can I ask for some assistance in how to get the value of ADRESH out of a pic12f675? It is a single port 8 pin chip and I would like to read the contents into a variable so that I can do operations on/with it. I am using AN1 as my analog input from a potentiometer. Thanks in advance.

    That's part of the kludge - it's some code from the net that I was trying to follow along with to get this up and running. It was from a different chip set - had three ports etc. I haven't been able to clean it up much because I didn't understand why they were shifting the bits. This is not the...

    Oh, yes - well, I will not be conformist in that respect. I already know what I want to do with my ADC ;) - I will keep it simple at first until I get my head around it. I am almost tempted to try it in ASM after spending a few fruitless hours in C.... that's a change, LOL. Most of it is because...

    Speedy PCB production using an inkjet printer

    Progress Ed, progress!! Nothing beats it :) I am still thankful that we have the ability to make PCB's at home relatively easily. My first was with a trace resist marker and ferric chloride. It actually came out in working order, I was very pleased. Now, with laser toner transfer, we can get...

    He is a bit slow and redundant - sometimes that is good to reinforce a point, other times it bores me to pieces. I sped the video up 25% and it was far more appreciable. More like some lectures at college where you are racing to keep up. I recall having to buy a cassette recorder for one...

    Wow. You are correct, my apologies - it was Laplace that I was giving headaches to! No, I made it through the first week well enough, 90+ score, but the second week wiped me out. I was not able to keep up due to math. 1N5819, also have the 5822 but its huge in comparison. The '19 was small...

    I was watching this the other day, this is where I got my notion of electricity following the path of least resistance... http://www.youtube.com/watch?v=OGa_b26eK2c&t=35m14s He seem's to know what he is talking about, was an engineer at NASA, etc. Let me know what you think, I was considering...

    LOL - I am confident in our postal quality! This time it's a simple envelope so I should expect it to be there by saturday. As for track mods - the only holes you will need to drill are the ones I showed in post 71 to accommodate the schottky and the two resistors. OH YEAH!! LOL, on both...

    Don't get me wrong, I think it's brilliant - but for a beginner its a lot to take in. One step at a time. Feel free, I am still getting on with the math of electricity o_O:oops::mad:. I think Ratch stays far from me, my last KVL/KCL homework assignment a few years back had him in pain. Poor...

    Upon further review of the multi tool design advisory, it looks like the dip is not necessary! Apparently, if you setup the circuit properly, you can direct the flow using nothing more than a resistor or diode :) Electricity follows the past of least resistance, so during programming, if it...

    It's serviceable, but not fun for frequent changes - which was the purpose of the board, LOL... sigh Interesting - I was bypassing all pins, so there is potential here to use a smaller dip switch and just isolate those three pins. I will experiment with that later. edit - success, just...

    8-Pin Development Board

    FYI - the existing board (ver 2.0) has a mismatch between pins 6/7 of the pic chip. No big deal as the software can select which is analog and which is digital, but it would be frustratingly long to look for that.... Ver 3.0 - hopefully this would fix the ICSP issue by isolating it completely...

    Run a wifi station and IP camera off of landscape lighting power?

    I had read that online as well but didn't understand what was going on until you explained the wiring Duke, thanks! So if I read you correctly, the sketch below would produce what Rich is looking for: Digikey part: 241-5-12 Good for up to 1A out at 24vac which means you now have up to 24watts...

    I may clean it again or pitch it out the window....:mad: I find the pickit 3 to be a bitchy little thing... It complains severely about its sensed voltage across the chip... It has to be within an 1/8 of a volt or it seems to throw errors.... I managed to get it to work on-board by removing...

    Thank you! LOL, but I did!! Do I need to hit it again? I had to be careful as the silkscreen side is not fully cured. Didn't want to ruin that side with the solvent. A copy is in an envelope for the mail carrier to bring to you ;-)

    Here is ver. 2.0 - now, I won't have to worry about bad connections on the breadboard!! The integrated ICSP should make it a breeze to reprogram as well as having a working MCLR circuit. The board has 16 thou traces, etched in Ferric Chloride (6 minutes) and tinned after failed soldermask was...

    Run a wifi station and IP camera off of landscape lighting power?

    Good point Bob, I thought it would be easy enough to find a xfmr, but a quick look through digikey had nothing for 12v as primary... I will keep looking as I find this to be weird... Richard, have you ever heard of Arlo by netgear?

    I have seen similar videos and have tried it myself. It works ok. The toner transfer method is more efficient and nearly foolproof with the right paper. So far I have had really good success with that yellow dextran coated paper. I would highly recommend that for a quick and easy way to do the...

    Newbie needing some assistance with a project.

    Interesting, was the ground for the amp previously separate from the lighting circuit? Were they both run off the same battery source? Post pics when you can.
