    External Resonator

    Hello Allan - Thank you very much for taking the time to work this out. I have read through your explanation a few times and feel I have a good handle on what's going on. You have hit on many details I missed in my original design/thoughts. My design never would have worked. For instance, I...

    That thought occurred to as well. I'm not sure, but I believe the transistors are there to provide a bit of a constant current to maintain somewhat stable brightness? There is every possibility that I could be 100% wrong about this however. That's part of the fun - experimenting. I will...

    External Resonator

    Allen - I took the time to read your post several times. There are a lot of details I had to understand that I normally gloss over. Yes indeed, the devil is in the details. All my projects up to this point didn't approach any limits of picaxe and I had a LOT of room for circuits that were...

    Thank you for responding. It would be a little bit down the road for the next project. I have a few projects that need finishing up first, like this one!

    External Resonator

    This thought has been kicking around in my head since I started working with your guys... Is there anyone here that takes on a project like this for pay? For instance I have one more project after this that I just will not have the time to work out (due to my glacial pace and weak think muscle)...

    So simple when you know what you're doing :) . I think this will be my starting point. I understand the commands and how they are being used. If further efficiency is needed, I may use PNP's and change the code as per Alans suggestion.

    Excellent info again Alan. I've learned more in a few minutes on this forum than I have in weeks of poking around on the 'net. Silly me, I knew of this forum for years and just never thought to look here.

    You guys gave me the confidence to move forward with this. I ordered the few items I needed today and will start playing soon. If interested, I'll post how it turns out. It's not a very exciting exciting project, but it does have it's challenges - form factor/3.7 volt operation.

    Excellent! I think this work.

    I only need to drive one small 5 x 7 matrix, so I'm hoping it will work. I think I understand what I need to do. I want to make this piggy back onto the ltp-305 so I may need to go surface mount as well.

    Such good information Alan, thank you for the help. There are drivers for this application that make more sense like the MAX6953 or MAX6952 but that darn serial programming is really difficult for me. I will keep plugging away at it and start prototyping up a circuit and see what I can do

    External Resonator

    Thank you all so very much for your help!! I've used the the 08m2 and 14M2 in many simple projects such as motor control, servo and led effects. I'm trying to step up my game a bit and use a picaxe to drive a 5X7 led matric display. I found this and it is the only program I understand...

    Hello! I was wondering where the hardware connections are for an external resonator on a 20M2? Thank you.
