Good evening all, I am attempting to wire a IMX6 solo computer with solo link to a Pixhawk 2 Carrier board via serial. I am seeing different diagrams on line, and note that this particular computer is not listed in the WIki on arducopter. I would be happy to write up the IMX6 for the wiki if I can confirm my wiring. This is the result of reading different post on Facebook that conflict with one another. So it is most likely wrong.
The main confusion appears to be around the SPKT specifically does the nonserial connection go to 3v3 or USART
most of the diagrams floating around seem to agree on the other pins.
Can someone help me out here?
This is all about getting the digital signal to the hawk.I’ve managed it with my Pixhack but there’s loads of confusion around which actual pin is the DSM input on the Pixhawk 2.1 SPKT port.
Spektrum receivers are not pinned out Like the Pin outs I have seen for PH2.1 and best I can tell the SPKT pin out for PH1 does not exist
From the Spektrum site
6 ELECTRICAL DATA
The interface to the remote receivers is a 3-wire bus. Pins are as noted in the photo below.
Pin Color Purpose 1 Orange 3.3VDC +/-5%, 20mA max 2 Black GND 3 Gray DATA
Have you probed the 3 pins? I’ve done what you’re doing and can’t recall the answer.
Just use a multimeter, and check continuity to ground and the 3.3v rail. This can be done unpowered. Once those two pins are identified, the third = signal.
The signal is depicted as center pin on the pinout. Which is why I thought that to be the correct one. That is if the end pin on the imx6 is indeed supposed to go to signal. Since there is nothing in the companion computer section on docs I will add one once I am sure the drawing is correct
Hi,
Did you manage to have it working?
What was the correct connection?
I’m planning to do the same, then I found this post here, it would be appreciated if you share your experience on this… like if you had any difficulties, incompatibility or limitations (in comparison to Edison equiped pixhawk carrier I mean)
No sadly I blew up my Pixhawk 2 attempting this
problem is no one knows what happened and no way to know if I attempt it again I will not do the same thing
So no IMX6 for me
Oh… sorry to know that… this is disappointing.
I think I will give it a try here, then I will post back if succeeded… otherwise I will come here to regret it
You must have know that already, in 3dr solo drone they have such connection, maybe we can trace it back to understand.
In what way did you “blow it up”? I am curious. Did the PH2 completely fail? Fail to take FW? Would it even turn on? I am considering the same thing and have a special carrier board that is supposed to be plus and play to the SPKT and TELEM1 ports so I am wondering how yours failed exactly if you don’t mind.
Can confirm that the documentation above is incorrect. Pin #1 is signal, Pin #2 is Ground, and Pin #3 is 3.3V.
Confirmed via measurement (multimeter) and alternative documention (See first image).
