The bottom of this page has info for different versions of the board. Apparently there are several different ones, so you need to make the right selection.

Have you tried posting to the forum over there? This is a bit outside the normal arduino stuff.

Pretty graphs, and simple formulas, :-)

What they are referring to is a \library subfolder in your 'sketches' directory, and not the one in the IDE directory. This way your additional libraries will still be present when you update the IDE in the future.

There are apparently 'many' possible reasons for this problem. Look at the following recent thread, and especially the search link given in reply #13. I went down the list of possible fixes until I found the one that worked for me.

Optiboot would need a significant re-write in order to work on the 2560, because the upload "protocol" that optiboot implements (stk500v1) only works for flash memory sizes less than 64k words (and the 2560 has 128k words.)

It would probably be easier to "fix" the stk500v2 bootloader.  It currently looks like it is not receiving ANYTHING on your wireless connection, which ought to be somewhat easy to figure out...

Unfortunately, I don't seem to have a lot of interest in "big" Arduinos.  My poor MEGA (1280 version) sits around neglected while I fiddle with 8k chips like the atmega8...
Does this mean that the maniacbug optiboot for the mega1284 will fail for programs > 64K?

I'll take a look at his link and see what it looks like, although the one I have linked is being used by many many people and they dont have a lot of trouble, there is a big community supporting the code,

I just dont know why I managed to apparently screw the upload, and then my stupidity burning the power reg seems to have finished the deal, i put a different power reg on the board as a test last night and it seems there is no rf output , i hope the module is recoverable, but i doubt it
Hmm, in that case, maybe I should take a look at HK's radio, LOL. As I mentioned, I've had terrible luck with the "usual" RFMxx radio libraries I've seen talked about around this forum - jeelib, mikem, attempting to use lowpower mod of jeelib with the mega1284.

Are you using it with one of the 433 transmitters shown in this page?

I guess I didn't realize this is an R/C transmitter-receiver system, per se. When I saw RFM22 and Arduino/328, I figured it was a standard radio system. Have you considered using it for a regular comms link, ala "It can even be programmed to utilize extra features such as telemetry and more!"?

From the looks of it, the board should be pretty darn simple. You should be able to tell if the Arduino is working by uploading any sketch, like a blink. And short of buying a new board from HK, you should be able to solder in a replacement RFM22 radio.

Another compatible with an RFMxx radio. I've not seen that one before.

However, FWIW, I've had nothing but trouble with every one of those radios and libraries I've tried, and from 4 or 6 different sources. What I have found is the VERY BASIC examples may work, but in general, they are so rudimentary that you have problems trying to do anything "practical" - eg, sending over data streams larger than a few bytes long. All you have to do is look at the examples, and you realize they never did very extensive testing on the library software.

I've wasted massive amounts of time with that stuff, but was mainly trying to get them to work with the mega1284 chip. This pertains to both RFM12 and RFM22 radios. The 328 chip support is probably more likely to work correctly.

That being said, I would recommend maybe going with Moteino devices from lowpower labs. I get the feeling this guy is really trying to provide good software support, and he seems to be very responsive to addressing issues that come up. The RFM69 radio is 100mW.
9  Using Arduino / Installation & Troubleshooting / IDE v.1.5.2 - board not found on: August 13, 2014, 03:27:06 pm
Sorry if this has been brought up before - couldn't find it via forum or google search. It may be buried somewheres in the gazillion online pages on Arduino.

I've been using IDE v.1.0 ... v.1.0.5 in the past successfully [WinXP machine], and have my custom mega1284 board info located in the sketch folder in subdirectory \hardware. However, I just installed IDE v.1.5.2, and my board does not show up in the "Tools > Boards" menu. It shows up fine in all the other IDE versions. DUH .... ??

Note that the libraries that are stored in sketch folder subdirectory \libraries do show up ok in v.1.5.2.

Another question - is there better support in v.1.5.x for 1284 chips, or am I going to have to go in and patch a bunch of library/etc files, like I had to do with v.1.0.5?
10  Using Arduino / Installation & Troubleshooting / Re: IDE load disaster, WinXP and IDE v.1.0.5 on: August 12, 2014, 08:21:18 pm
Well, I seem to have fixed the problem now. I did a google search on the problem [which I probably should have done at the beginning], and found loads of different people had seen the problem before, and who also had loads of different "fixes".  No two people seem to have fixed it the same way.;_ylt=A0oG7nphKfpNLmUAKzml87UF?p=arduino+load+error+Lunch4j

So, after going down the long list of putative fixes, and finding NONE of them worked for me, I finally found one that did work, see reply #14 here, where it says "All you need to do is to delete the file or directory".

What he means here is to delete preferences.txt, and not REFERENCES. Then, when you restart the IDE, it creates a new file from scratch. It worked for me. I'm not sure what the problem was with the previous preferences file.
11  Using Arduino / Installation & Troubleshooting / Re: IDE load disaster, WinXP and IDE v.1.0.5 on: August 12, 2014, 12:39:15 pm
Thanks, I am familiar with ending processes that way. As it turns out, the javaw.exe process is NOT started with bootup of the PC, but is started when the IDE is loaded. Then, if I kill it during IDE loading, the IDE icon disappears - and IDE loading is obviously terminated. So, this is no help, duh?

Just to check, I went to the Control Panel and did an update of Java for the machine, but this had no effect on loading the IDE. Still will not load, so I seem to be out of luck on this machine. Thanks for the help, guys.

Dealing with Windows reminds me of the old Outer Limits show ... unfortunately.

There is nothing wrong with your television set. Do not attempt to adjust the picture. We are controlling transmission. If we wish to make it louder, we will bring up the volume. If we wish to make it softer, we will tune it to a whisper. We will control the horizontal. We will control the vertical. We can roll the image, make it flutter. We can change the focus to a soft blur or sharpen it to crystal clarity. For the next hour, sit quietly and we will control all that you see and hear. We repeat: there is nothing wrong with your television set. You are about to participate in a great adventure. You are about to experience the awe and mystery which reaches from the inner mind to – The Outer Limits.
... awe and mystery, yeah right.

I am using XP for many years and time to time I've obtained "Launch4j" error message.  Usually, another start of IDE helps and in the worst case I had to kill Java process, so I don't think it is XP problem, but in fact I didn't investigate deeper this error .
Aha, can you explain what you mean by 'kill java process'? Where do you do this?
13  Using Arduino / Installation & Troubleshooting / Re: IDE load disaster, WinXP and IDE v.1.0.5 on: August 11, 2014, 11:41:40 pm
Hmm, I figured Win8 would be shipping with all the new notebooks now, and Win7 was scuttled.
14  Using Arduino / Installation & Troubleshooting / Re: IDE load disaster, WinXP and IDE v.1.0.5 on: August 11, 2014, 10:21:13 pm
Foo. Everything else works fine, just the Arduino IDE won't load. It probably is time to buy a Win8 machine in any case.

In the meantime, I dusted off my ancient 10-YO WinXP notebook and installed IDE v.1.0.5 on it, and can upload fine to my mega1284 boards, so at least I can work again. Thanks.
15  Using Arduino / Installation & Troubleshooting / Re: IDE load disaster, WinXP and IDE v.1.0.5 on: August 11, 2014, 03:42:02 pm
Well, I haven't fixed this yet, but discovered run.bat is no longer included in the IDE directory, but had been up until IDE v.0016 or so, where it reads as follows:
@echo off

REM --- if you're running out of memory, change the 128m
REM --- (which means 128 megabytes) to something higher.

set JAVA_HOME="java\bin"

if %JAVA_HOME% == "" GOTO Error

set CLASSPATH=java\lib\rt.jar;lib;lib\build;lib\pde.jar;lib\antlr.jar;lib\RXTXcomm.jar;lib\oro.jar;lib\registry.jar;lib\mrj.jar
set PATH=java\bin;lib;%PATH%

REM start javaw -ms128m -mx128m



echo *** Error: cannot execute Arduino
echo *** Reason: lacking the directory where to find Java in your computer
echo ***
echo *** Fix: Edit run.bat and add the JAVA_HOME directory
echo ***      at the 'set JAVA_HOME=""' line
echo ***
echo *** then call the batch file run.bat in order to execute Arduino

echo Bye.

I did try moving this into the IDE directory and executing, and got the following error msg:
Exception in thread "main" java.lang.NoClassDefFoundError: processing/core/PApplet
Caused by: java.lang.ClassNotFoundException: processing.core.PApplet
In any case, it looks like the main java install on my machine hasn't been updated since 24 Jan 2014, so recent any java update is probably not the problem.

Still scratching the head. What a mess.
