Well it's been a while since I posted an update. I ran into a wall and figured it might be useful to somebody if I post about it instead of glossing it over. I started working on the next episode and was hooking up an SD card to the sensor platform. I had to face some realities. The code to work with the SD card was pushing the memory usage high enough as to limit some of the other features I have planned. Also, the PIC18F2455 is a 5V device and requires special circuitry to be able to interface with a 3.3v SD card. I decided it was time to look into another PIC for the project. I went to Microchip's site and really poured over the chip comparisons and decided that the PIC18F27J53 was just what we need.
