BOSCH BMP180 digital pressure sensor on I2C bus

[CAI_Support]

With testing firmware 3.02.18a loaded, hook up an I2C BMP180 sensor board, I am reading between 1055 hPa and 1056 hPa using Ross' test PLC code.  Temperature is 24.3C right now.
 
We initially hooked up that BMP180 sensor board to 3.3V and did not work.  Ross pointed out there is a regulator on this sensor board.  Once we moved the power supply to 5V, it stated working.  This little sensor board sold on ~Bay for $2.38 with free shipping.

We initially planned statuswin.htm in the PLC screen not auto refresh.  However, based on Ross' request, we have changed that auto refresh similar like index.htm page.  For this, we uploaded new zip file.  If you already have 3.02.18a firmware, you don't have to reload firmware, only use /webguiload to load new gui files, that include the auto refresh in the statuswin.htm through the link on the PLC screen.  If you don't every use that, then you don't have to update.
