pressure sensors and AXE033

[jpv01]

I like to make my own instrument for gliding and looking for pressure sensors on i2c. barometrec and about 25mbar diff. Anyone an idea where to buy?

BTW, i am new on the picaxe but what a great controller..... I connected a AXE033 and wondering if i still could use the 10-bit A/D converters on it and sent the value by i2c to the picaxe. Or am i talking bull now........

"I connected a AXE033 and wondering if i still could use the 10-bit A/D converters on it..."
The AXE033 is an LCD display, it does not have any A/D converters on it.
The PICAXE X range have 10-bit A2D converters which you could certainly convert to a suitable output to display on an AXE033.
Not sure about any I2C pressure sensors but if they exist, I'm sure someone will know and get back to you.

I ordered a couple of i2c barometric pressure sensors from sensortechnics in germany fairly recently. Haven't been able to get them working yet, but I have an older 28X. I believe they *should* work with the newer firmware version.
