The Lisp Badge mini computer<\/a> has turned out to be quite useful and fun for little hardware hacking projects. Its designer, David Johnson-Davies<\/a>, suggested that the SMART<\/a> Response XE<\/a> would make a good off-the-shelf uLisp<\/a> computer, eliminating the need to build one from scratch.<\/p>\n\n\n\n

I ordered a few SMART Response XEs from an auction site to see what was possible. I found Larry Bank<\/a>‘s excellent Arduino library<\/a> and fdufnews<\/a>‘s schematics<\/a>, which provided a great starting point. With guidance from David, I completed an initial uLisp port<\/a>:<\/p>\n\n\n\n

To load the code, I use an ISP programmer and a special PCB with POGO pins:<\/p>\n\n\n\n

On Debian, I run:<\/p>\n\n\n\n

The SMART Response XE uses the ATmega128RFA1 microcontroller<\/a>, which has a ZigBee IEEE 802.15.4<\/a> transceiver. David and I are discussing adding uLisp functions to make use of this capability.<\/p>\n","protected":false},"excerpt":{"rendered":"
