Pleased someone else finds it useful too.
In addition to the 1KB version I have now also published a 2KB version that is much faster than RS232 (1.43 seconds to program and verify 15KB program versus 3.76 seconds over RS232). The latest 1KB version is now a little faster than RS232 at 3.02 seconds.
I still recommend the 1KB version, but if you’re a speed freak and prepared to give up another 1KB the option is there.
PS: Great board, thanks!
I’ve modified the Optiboot bootloader to support loading programs over TCP/IP. This is very useful if you need to reprogram a board remotely.
My modified Optiboot still supports “normal” serial reprogramming, and the bootloader is still under 1KB in size.
Details and download link are on my web site.
Note that you need an AVR ISP programmer to reflash the bootloader. A cheap parallel port device is suitable.
No public wish lists :(
