I don't mean to use A->D conversion; instead, write a terminal emulator and use it as such; which gives me, say, 40x24 terminal (960 bytes of RAM) with 8x10 character cell (2.5K) in EPROM. Kind of what microoptical offers in AV-1. I am a decent C programmer but very poor with microelectronics; so it is amount of soldering, not programming, that scares me :) What I am asking for advice on is: which microcontroller should I use? The one I am looking at now is: http://www.atmel.com/dyn/resources/prod_documents/doc4136.pdf but that is about the first think I picked up. Particularly, I am wondering about the following aspects: 1) conectivity: it would be nice to have both USB and RS232(maybe at TTL level); wireless? 2) packaging: should be easy to solder, have little or no external components 3) power consumption: should be about that of the display or less 4) processing power: should be able to generate 60 frames per second 5) onboard RAM: if it is a simple text terminal, 1K or 2K should be enough; for individual pixel addressing at 4bpp it is 37.5K; for 3x4bpp color it's 112.5K. and of course, development tools should be publicly available.
