Choice of a logic analyzer for Assan V2 protocol

What you are linking to is a Salea Logic clone.

I've repeatedly said that discussing knockoff Salea hardware is verboten here. It is very likely a license violation in the US to use their software with a clone.

Using one with sigrok would be fine, but very few folks do that.

I am very happywiyth my Salea Logic, and their support, and find their software to be intuitive to use. I can understand not being willing to pay Salea's price, but I cannot condone the use of their software with Chinese clones, and this forum isn't the place to discuss it if that is what you want to do.

As far as capturing the interesting parts, you need to identify the SPI ports (SCK, MISO, MOSI, and CSN) depending on the board layout, this could be very easy, or involve tricky soldering. We can help you with that if you take pictures of the Tx.

Once you have the LA attached to the proper ports, you need to capture power-on, and the binding sequence. Then you'll need to capture each function individually and document what you did. for instance sweep throttle, elevator, aileron, rudder from min to max. Then sweep the trims from min to max. Then flip any switches.

If there is no encryption in the protocol, that'll likely be enough to get it working. If they've encrypted it, things will be harder, and you may need to also attach the LA to the Receiver and/or hope for a Math expert to come help (as was needed for DSMX)

I agree baout setting up sigrok. There is this page:
sigrok.org/wiki/Windows
which provides instructions on getting up and running on Windows.
I've never gotten around to trying it myself.
I wish the clone manufacturers would bundle sigrok instead of (likely) illegally bundling Salea's software. It would also give sigrok a boost which it could use.

I have generally gotten by dumping SPI or occasionally raw data from Salea and post-processing it in perl. I like being able to quickly look at the waveform to make sure I got what I needed, but as you said once you are actually working on the protocol, that isn't much use, and the process of a dozen clicks to capture, and export the waveform is less convenient than streaming the data would be.

I expect that next time I work on protocol stuff I'll setup sigrok and give it a shot. I'm in a weird situation where my primary Deviation workstation is a Windows machine running Ubuntu in a VM. I am not sure if sigrok through the usb forwarding will work or not.

As I didn't follow closely the different threads on the protocol side of things, I didn't grasp that it was verboten to talk or link about it.

Sorry fort that, I removed the link.

I should clarify that there is nothing wrong with that hardware (that I know of), but it is sold specifically to be used with Salea's software which is where my objection comes in. If someone would put together a newbie instructions for using one with sigrok, I'd have no complaints. I may give that a shot myself; you aren't the 1st user to ask about this, and I agree that an official Salea is not cost effective for someone who is unlikely to use it often.
