Hi Andrew, I've been running a test of a RELAY4 here today to try and duplicate this, and no trouble yet at least. I'm driving 12V coil relays, have a 12VDC supply into the RELAY4 and EtherMega running the test, and using digital output pins to control the RELAY4 input lines. Would you be able to se...

Hi Mark,
This is a quick late night catchup on this post so please excuse the short post,
absolutely, we're happy to not only reprogram your board by ISP, but also send you a bonus if you like too!
Can you please email us or PM me your shipping address and contact details? '
Cheers,
Marc

Wow thanks for the excellent description and background info! We've just done a tutorial and background that I think answers most of your questions on hung sketch recovery and the bootloader, it's here, hope it helps and gets your sketch loaded ok. Please let us know how it goes and we can assist mo...

Hope this helps, we've just done a tutorial and background info on hung sketch recovery and the bootloader, it's here to help if you need it:

Hey that's excellent news! :) We found that Mac and Linux do connect faster to get into the bootloader a bit easier. We've just done a tutorial and background info on hung sketch recovery and the bootloader, it's here to help anyone! http://forum.freetronics.com/viewtopic.php?f=27&t=427&p=1346 Cheer...

EDIT: If you use the latest board profile the tone() function and other hung sketch culprits now work correctly on newer LeoStick V2.0 models (the Getting Started page shows you how to identify your model.) If you have an older V1.0 LeoStick then it is possible to update to V2.0 . Scroll straight t...

Hi tobiw, Welcome to the forum! :) Recently there was an updated bootloader for the ATmega328P based Arduino boards, which includes the Uno, Eleven, EtherTen, USBDroid, etc. It specifically fixes the 28k issue, there's a lot more info out there googling for "arduino bootloader size limit fix" or sim...

I've run a few tests, and it works ok with a micro SD card. There are a few things to look at in the setup: The example I have run is from the 1.0 IDE and is File>Examples>SD>listfiles - In setup() the SPI CS output pin needs to be 53 (10 on most boards, 53 on all Mega type boards) so line 32 become...

Hi Steven, What kind of errors with the SD card do you get on the Mega? Looking at the schematic of the EtherTen and EtherMega, at first look the functionality from the library point of view should be just the same. The EtherMega SPI is D51, D52, D50, and EtherTen is D11, D13, D12, but that is expec...
