Of course in your case what you really want to do is calibrate the oscillator to give reliable serial transmissions, so the Tiny Tuner is probably the most appropriate method for your situation.
I will certainly be giving this a go when I exhaust all other options, because I think its a simple fix. Apparently with a crossover wire from reset to ground. But when I do that I get nothing in the serial monitor
If they slowly go in and out of sync, then it sounds like they are running at the "same" speed, one is just a bit faster. If the clock is off by 8 or 15MHz, the LED would blink way more slowly. It would be hugely obvious that one was twice as fast or even eight or sixteen times as fast. They wouldn't be close at all.
From what I'm seeing, it looks like the chips must be running at a decent speed. I just don't get why I'm getting messed up feedback at all different baud rates.
Yes just a wire, it keeps the Atmega in constant reset.
The alternative is to remove the chip from the UNO, but I find that too risky.
I have tried a wire, and i get NOTHING in the serial monitor, the TX led also doesnt flash. If I remove the wire and leave it open the TX led begins to flash again! lol! I took out the chip and I couldn't get the com port to show up, but I think theres another reason it was doing that. I will try again without a chip in the arduino when I get some free time. But so far from what I have read from other people that have experienced this issue, they seem to use a wire from reset to gnd, or they use coding badly's knock library. I tried setting up his library, but I couldn't work out which was his latest version of TinyISP. I would totally use it if I could figure out which is the latest version, and how to install it. LOL!!!
Has anyone followed my tutorial? Thats how I setup the Tinys. Is this the correct way? Is there a step in there thats not right?
Here is a image of the results I get:
I will need to try out taking the chip from the arduino again, and test it that way. Have I wired it wrong? Why would the TX light not show up at all with a wire on reset and GND ? Ill have to purchase one of those usb-serial converters.
Thanks very much all of you for helping me out with this nooblike issue. I really appreciate it!
