i just bought a pack of these from maplin and regarding the HD44780-compatible LCD...
i know the simplest thing i can do is link the pins directly to my picaxe 28x1 but i was looking to save pins and build my own little three pin pcb "serial backpack" .
any idea what would make a good intermediary chip to do the job for me?
essentially i want to give my bot AKIRA a direct output as its programming is running (to fix problems first and then to communicate) but i'm getting seriously bogged down by all the info that is out there (amongst other things) so i'm hoping someone out there has experience of a essentially cheap alternative to the actual serial backpacks
