Pixhawk 2.1 - issue with I2C2 port

Started by Simon L.. Last reply by Stefan Powell Jun 17. 21 Replies

I have been trying to get my digital airspeed sensor to work and while doing some research I came across this post that claims that the "I2C2" port on the PX2.1 does not work:…Continue

Discuss choice and application of GPS's to use with the new PH2.1

Ken McNamara sent a message inquiring about what GPS to use with your new Pixhawk 2.1: I believe this is a great subject for a new discussion. Right now, I believe there is only the "HERE" GPS that…Continue

was heavy into the early days of electric RC cars.... needed a cheap radio link for a robotics project...next thing you knew I had 10+RC cars and a crap load of trophies and ribbons. Was heavy into mfr/designing/marketing custom electronics for the industry back then. (power side)...didn't realize the hobby simply 'left the ground' (got airborne...literally) Doing for autonomy...I was attempting in the late 80s trying to keep a road car pinned to the inside wall of a race track. Now it's just all 3D (and a hell of a lot cheaper $$!)

wow, love the router.. Extra heavy duty! I see you've been tinkering a lot over the years. So from Cars to drones? . I've studied Agriculture, college level mechanical engineering and now I have 1 year left in Industrial electronics, also college level. I've only worked on lightweight projects up to now (except for my house).

ha ha ... (? advanced user ?)
nah...just a fellow madman geek... LOVE to experiment

my normal work looks more like

home designed/built FI on 40 year old cars   GT6 engine set back in the frame 6" in a '75 Spitfire

and stuff like

will probably be cutting CF soon for my own frame design

I'm glad you are in here with me: I can certainly use advice from an advanced user like you.. As for my purchase, I guess I got super lucky; too bad I have no idea what to do with an Edison Chip. I suppose at some point I will want to tinker with a companion computer but for now I will be quite content with achieving autonomous flight on my fixed wing aircraft.

This is the first plane I will attempt to automate with my new PH2.1:

She's called the Junco3 , has a wingspan of 48 inches, weighs 2600Gr. (5 lbs 12 oz) and is powered by two 45 Amp setups in 3s (35-30 1400Kv with 10x4.7 props). Her cubic wingload is about 10.5 so she's a very aggressive flyer but flies 'on rails'. She has flaps for slower landings.
I will post pictures next week (my mother has my camera) but here is a CAD drawing:

the 'edison-less' base does NOT have the ports on the side (as mine is...no edison)

Comment by Paul Tegler on May 8, 2017 at 4:10pm

simon.... As I also have a FlytPOD here, I'm running ROS, OpenCV and FlytOS, basically duplicating the POD's capabilities but instead of WIFI based, will use the 915 tlelem and Ardupilot and related GCS.

right now , plans are mostly collision avoidance and optical tracking (gimbal control)

talk about convoluted.... using an Arduino Uno to read/control x6 sonic sonars (4 sides one top one bottom) the Arduino feeds the Odroid, which feeds the Pix2.  The Odroid can handle the cam directly. Using openCV for the tracking.  Next is playing with SLAM (Spatial Localization and Mapping)

I think they sent me the Edison version by mistake.. does the standard carrier board have the internal edison port and 2 usb ports on the side anyway?

Comment by Simon L. on May 8, 2017 at 1:18pm

Nice, Paul, what do you use the Odroid Xu4 for?

Comment by Paul Tegler on May 8, 2017 at 12:45pm

...been playing with mine (on the bench) for about 1.5 weeks.... working out the differences in MP to configure the 2 like my previous 1's...figuring out the ports. Got LEDDAR working (gps2 port is SERIAL4) Frsky (via converter ckt) to Telem1, (serial1) MINOSD and 915 telem on Telem2 (SERIAL2) ... now need to get the Odroid Xu4 hooked up and talking.  HERE GPS seems pretty decent...indoors next to all the computers and electronics i'm still getting 14 satellites.

Just got the package in the mail this afternoon.. I made sure everything was intact and in place.. I will provide unboxing pictures and comments next week as I am in Exam week right now and have to prioritize my education... sigh   Its sexy.. that I can tell you!
