Making Progress. Update 4-20-2008

Here is the proto version of the Basic Stamp 2px (blue chip), DS18B20 temperature sensors (little black things to the left of the blue chip), and connection to the GPS receiver (red and white wire on left to the top). The green chip on the right is a MAX1668 temperature monitor with 1 local and 4 remote sensors. Unfortunately I have not been able to get it to talk to the BS2px over the SMBUS, yet. After a little research I think I have figured out how to "bit-bash" the SMBUS protocol out of a synchronous connection from the BS2px but have not had the time to try to develop the code and test it.

There are some other components on there like the LED bars and resistors such that I am not using right now.

As for the main program code, things are going good. I got the DS18B20 sensors to talk using an I2C link. I also have the GPS data acquisition part working over a serial link. It took a while to figure out how to correctly parse the incoming data from the GPS receiver.

On Thursday I ordered the serial LCD panel, I2C EEPROM memory chips, and the atmospheric pressure sensor. I'll update again after I get those components working and post some pictures and maybe some video.
