How can I use Astro Pi Sense Hat
I'm trying to use a sense hat with it's integrated IMU and environment sensors. The IMU of the sense hat is a STM LSM9DS1 which is supportted according to the documentation.
There should be a compass tab ( But there is none.
In the I2C section I see three objects in the pulldown list (STM LSM9DS1 - 0x6A, BMP180 - 0x77, HTS221 - 0x5f).
I can add BMP180 and HTS221, but not the STM LSM9DS1. The field add/update sensor remains empty.
something wrong with my installation? What can I do?
thats old documentation
I too am trying to set up Raspberry Pi 3+ with Sense Hat.  The calibration within the PyPilot can see the sensor for heading, pitch and roll and works ok, but I need help getting it into Signal K so that the instuments and sail gauge works etc.  Later I'll be needing help getting my old analog depth/water speed and wind speed/angle sensors working too.  I can also use a recommended USB GPS and AIS VHF dongle that will work without much trouble.  Then I think I'll have a complete chart plotter/navigation system for my 1978 Ericson 27. Thanks for any help that can save me time figuring this stuff.

I'm using the Raspberry Pi Sense Hat that was created for the Astro Pi Mission in Space on the International Space Station.
The IMU is LSM9DS1 and is picked up by Pi Pilot for Compass, Pitch, Roll and Yaw etc.
I need help adding the two environmental sensors to I2C for Open CPN. They are LPS25H for Pressure and Temperature at address 0x5c
and HTS221 for Humidity and Temperature at address 0x5f. How do I add these to the drop down for I2C sensors?
I can also use some help getting my analog depth and wind speed/direction added to my Pi.
Thanks, Johnny

Here's the link for the sense hat pinout etc.
