IMU connected to a Laptop? - McNugget - 02-13-2020

Hey guys,

I'm wondering if I should switch from my RPi to an old laptop to run OpenPlotter with OpenCPN for performance reasons in OpenCPN. It's purely aesthetics but I'd like to have a smooth experience for the chart plotter.

The only reason I can see why this would be slightly more complex than with the rpi is the IMU.

Any established, known working way of connecting an MPU9250 to a laptop such that it works as easily as with the PI?

i looked into it but never tested anything do a google search and you will find a device "Bus Pirate" and some i2c hacks to memory module's and vga connections even then i don't know if it would be compatible

you could just use the laptop to run opencpn I have done that in the past. There are windows and Linux versions. you just point the connection to the rpi

what ddelorme said would be the easiest way...let the pi handle the sensors and send the data to the laptop running opencpn..
