Figured out the problem. Using Arduino 1.0 libraries apparently you need to use the Wire.write rather than the Wire.send method to get this guy to work.

if (ARDUINO >= 100)

Wire.write(a); // sends register address to read from

else

Wire.send(a); // sends register address to read from

endif

You might want to adjust the sample Arduino you published in the link above…

trying to get sensor to work for me – I’ve tried a number of the code bases posted here for the arduino and with all of them get stuck during the calibration step. specifically around this call (from Sparkfun’s code):

ac1 = bmp085ReadInt(0xAA);

as I debug this method it seems to hang in the function bmp085ReadInt() method:

Serial.println(“bmp085ReadInt – 1”); Wire.beginTransmission(BMP085_ADDRESS); Serial.println(“bmp085ReadInt – 2”); Wire.send(address); Serial.println(“bmp085ReadInt – 3”);

“bmp085ReadInt – 3” never shows up in the serial output window.

any suggestions? i ordered a couple of more just in case I have a bad one here

the two bands in which this operates is located in the 70cm and 33cm band. both of these are secondary allocations for the amateur operators. the 260Mhz appears to be allocated for “fixed, mobile, and mobile satellite” uses (http://www.ntia.doc.gov/files/ntia/publications/2003-allochrt.pdf).

personally, this is a great little device – and since i am a ham operator i plan to use this within frequency that i can legally use in a fun science project with the boys. a small series of stations that collect weather information and xmit back to the “mother ship”.

HOWEVER, it appears that on page 3 of this document: http://transition.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet63/oet63rev.pdf that

“Hobbyists, inventors and other parties that design and build Part 15 transmitters with no intention of ever marketing them may construct and operate up to five such transmitters for their own personal use without having to obtain FCC equipment authorization.”
