For those of us who aren't ashamed to love cute pico's . JJRC H20 Mini/H30 Mini. Just TX on, bind. The rest after sleep.

No problem mate. I get it. I'm still waiting on my Chaoli 413's anyway

Ok. Well, Christmas already here in Oz, but I'll get that up today. Confirmed both bind to the each others TX's. Had em both bind and flying at the same time. It ended in tears .

Here's 3 capture files. The first is the same as yesterdays, just titled specifically. The next 2 are with the other controller (H20 Mini).

I captured the binding process of both the H20 & H30 Mini using the H20 Mini controller, to give you a constant/comparison. Looked the same to me, but I wouldn't know how to see subtle changes. Hope everyone had a good Christmas.

It just occurred to me that the first capture I took was the H30 Mini. Hence your surprise? While taking them I had it in my head that the hex had the bigger number (H30) for some reason. No need to respond, I know you've got your hands full. I'll wait until you've have time. Just wanted to clarify.

I have the H20H. And got one of the logic analysers I ordered here the other day. The problem is that it is not the logic analyser that you recommended here (I am still waiting for that one from eBay). But I might be able to help anyway.

The analyser that I have got is this one: www.banggood.com/LHT00SU1-Virtual-Oscill...5.html?rmmds=myorder

I'm using a Mac so I figured Sigrok would be a good place to start. I have installed PulseView. And my device shows up under USB when I choose fx2lafw (generic driver for FX2 based LAs). It shows up as "CWAV USBee AX with 9 channels".

But my problem is that when I hit OK it says "Failed to Select Device".

Would you recommend some other software? Or do you have a bit of guidance on Sigrok?

If I've only 1 that won't be possible to control several H20H with deviated transmitters in the same area without interferences ...

I got 2 on the way goebish. Still about a week or so before they'll be in my hands, but I'll keep tabs here. If you still need them, happy to oblige.

I am current out of town (not having my devo/H20H with me). I won't be able to test the build until end of Feb.

Thanks for the work anyway.

I managed to get my LA working with sigrok on mac.

But I am completely new to capturing. Anyone care to post an image of the H20H remote with details on where I need to connect the LA?

Eirikso,

(need CSN, SCK & DATA, Vss = ground)

Thank you both. So, this is my first attempt for a capture of one of these remotes. Probably completely useless. I used 8 MHz. And saved ".sr"-files from PulseView:

Edit:
D0 = CSN
D1 = SCK
D2 = DATA

Let me know if it works. And if not: any hints on what I have done wrong?
