Hi Felix,

Thanks! I won't be using baro for now, so it should be all fine! 

I'm on the 5.0.0 branch, and have Ubuntu 12.04 running. I had to remove brltty, but my ground modem does not work! It just fails to connect to it. Dmesg says that it's been plugged to /dev/ttyUSB0, and the modem works on an older setup running a different ubuntu version. Any idea whats happening?

Hi Uttam,

I haven't had time to refactor and clean up the aspirin2_i2c driver so far.... as the wiki says it currently doesn't have the default sensitivities for accel/gyros defined, but you can easily just take the same defaults and put them in your airframe file.
The bigger "problem" is probably that the aspirin2_i2c driver currently does not read the mag...

And yes, you can use the aspirin_v2.2 driver to read accel/gyro and mag over SPI on LPC2148 boards.
However on the Tiny2.11 SPI connector there is only one SlaveSelect line/pin and that is also currently the only pin defined in the board file...
So if you don't want/need to read the baro (via SPI), then you have to pull up the BARO_CS line on aspirin so it's not floating.
If you want the baro, you would have to add definitions for another SlaveSelect (ChipSelect) pin to the tiny_2.1.h file....

Hope that helps,
Cheers, Felix

Hi guys,

Is it possible to use the Aspirin 2.2 IMU with a Tiny 2.11 over the SPI bus? I ask because the wiki says the factory calibration of the IMU is used only when the Aspirin 2.2 is used with the SPI driver and not with the I2C driver.
