So far I have not figured out the reset trick with rts - (My max232 chip doesnt have the connection for that) - but I don't think I need to in my case?
If you are going to wander around carrying the programming Arduino, why not use something like this? ...http://www.gammon.com.au/forum/?id=11638Put the updated sketch on the SD card, connect it up to the ICSP header, and program it. My sketch on that page has a serial interface. You could carry a laptop around to "talk" to it, or revamp a bit and use a button to start the programming process and a couple of LEDs to indicate progress.I made the whole thing up onto one fairly compact board like this:
Anyway you have created yet another great arduino application with this project that really expands ones ablity to support arduino boards independently of the IDE.
Is it my idea or has your project actually evolved a lot in the last half year or so?
