11 years ago The AVR port hasn't been maintained in a while (except for some codebase-wide changes). I stopped maintaining it when the firmware binary could no longer fit in my ATmega328. At time of writing, you will need an AVR with at least 64 KB of flash.

11 years ago Hi,
I've updated the AVR port to include a dummy displayAddress() function (it isn't ever used anyway). It should build (run make in avr directory) now. Keep in mind that I consider the AVR port deprecated for the following reasons:
However, if you are interested in the AVR port, I can help you. The tester in avr/tester is outdated; would you like me to update it?

11 years ago if it is to large to fit onto an ATmega328 I might have to re-think my idea a bit, and the 23 second's does seam like to much, You mentioned arm, do you think it would work on a beaglebone? http://beagleboard.org/bone

- I ran out of flash space on my ATmega328.
- I was running out of RAM.
- Signing required too much time: ~ 23 s. Even with hand-optimised assembly, I estimate that it could be reduced to ~ 3 s, which is still too long.
- 32 bit ARM/PIC32 chips have comparable costs to high-end AVRs while being much more powerful.

The beaglebone is much, much more powerful than any of the microcontrollers I was targeting. It is capable of running Linux; for comparison, all the code for the AVR, LPC11Uxx and PIC32 ports are "bare-metal" (no operating system).
You could probably get Electrum running on the beaglebone. Then you would have the advantage of a much nicer interface. It is definitely feasible to write a beaglebone port, but it would involve implementing all the platform-specific functions described in hwinterface.h. The port would also be very dependent on the display/input devices used.
