Eachine E016H support

[BLeibbrand]

Hi all, Thanks for the wonderfull work. I love flying with my Taranis X9D+ and IRX4+ TX Module in combination with an Eachine 010.

I bougth an Eachine E016H which looks similar to the E010 but with more prop protection. I have kids and dogs so protection is needed. But sofar I'm not ably to get the combination working. Which protocol do need to use, or do you have to reverse engineer it first?

OpenTX Companion - 2.2.3 Taranis FW:opentx-x9d+ version 2.2.3 (ae5ac05b) IRX4+ - original (no flashing yet. Need to get USB - FTDI connector)

If it doesn't work with any (sub)protocols with DeviationTX or MultiModule then it needs to be reverse engineered. Can you open the transmitter and quad and tell me which ICs they're using ?

[BLeibbrand]

Hello Goebish,

Thanks for the quick response. I did some home work. I hope this helps.

Yours Sincerely,

[goebish]

I see nothing. If you want to post pictures I suppose you've to use github, you can't insert them in an email.

Ok, that's a PAN163CX (MCU with built-in XN297L transceiver), it can be reverse engineered, but not with a logic analyzer. If someone dropships one to me I can take a look.

[BLeibbrand]

Hello Goebish, I just had time to unscrew the transmitter. The transmitter pictures. The chip: XNS1042CV extra info about transmitters with the XNS chip: https://www.google.com/imgres?imgurl=http%3A%2F%2Fimg.over-blog-kiwi.com%2F0%2F55%2F43%2F29%2F20181129%2Fob_463a88_xwqz238505.jpg&imgrefurl=http%3A%2F%2Fchezcyril.over-blog.com%2F2018%2F11%2Fmini-drone-pliant-volcano-w606-16-un-drone-qui-se-pilote-grace-a-un-gant-et-au-mouvement-de-la-main-gyroscope.html&docid=ztPRrdg6XvaYsM&tbnid=nXG7m4h00eZ-eM%3A&vet=10ahUKEwjnhpD3467gAhWCPFAKHdPHDGEQMwgoKAAwAA..i&w=1205&h=544&bih=642&biw=1396&q=XNS%201042CV&ved=0ahUKEwjnhpD3467gAhWCPFAKHdPHDGEQMwgoKAAwAA&iact=mrc&uact=8

[goebish]

As I said, I believe it can be reverse engineered but I don't have one. If someone wants to dropship one to me send me an email @gmail.com

[BLeibbrand]

Great !! Which steps do I have to take to get it into my Taranis / iRange?

[goebish]

I've to cleanup my code then I'll contact @pascallanger so he can add the protocol to the 4-in-1 module firmware.

[BLeibbrand]

What do you think of the indoor capabilities?

[goebish]

It's fun but quickly boring ;) It should be perfect for a beginner or a kid as throttle is easy to manage.

[BLeibbrand]

Did you also enable the three fly modes?

[goebish]

Fly mode is always set to "expert" then you can set lower endpoints on your transmitter if required.

New Multiprotocol version 1.2.1.26 available on GitHub: https://github.com/pascallanger/DIY-Multiprotocol-TX-Module

Thanks to Goebish the E016H is now supported: Protocol E01X (45) Subprotocol E016H (2) Channels: CH5=STOP CH6=FLIP CH8=HEADLESS CH9=RTH Please test and report.

Pascal

[goebish]

Thank you! @BLeibbrand please report once you've tested.

[goebish]

@pascallanger I think there's a mistake here: https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/04ed613ca3bd4bcda53457504adeca7aa9053168/Multiprotocol/E01X_nrf24l01.ino#L269 it should be XN297_SetTXAddr for E016H and HS6200_SetTXAddr for E012 & E015

[pascallanger]

Thanks! copy and paste issue... Corrected in v1.2.1.27.

[BLeibbrand]

Hello Goebish and Pascal,

I have soldered the connectors in my 4in1 and have to wait untill Monday to pickup my USB-TTL to get the bootloader installed. As soon as I have tested it I will inform you.

Yours Sincerely,

[BLeibbrand]

The ST-LINK V2 arrived today. No luck in connecting to the 4in1. Any help for the cable connection would be fine. And 4in1 GND, TX, RX

[pascallanger]

Why a st-link? you need a FTDI like the one in the documentation: https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/master/docs/Compiling_STM32.md#tools-required Have you tried to plug the USB to your PC? The latest modules are shipped with the bootloader flashed.

[goebish]

The STLink connects to a SWD interface (swclk, swdio, gnd), if you want connect to UART (gnd, rx, tx) you need an USB to UART adapter (FTDI dongle) instead. I'm not a 4-in-1 expert, you'd better ask on rcgroups https://www.rcgroups.com/forums/showthread.php?2165676-DIY-Multiprotocol-TX-Module/

[BLeibbrand]

I already tried the USB: It's a 4in1 from june 2018. So I'll get a USB-UART and after that we can continu.

[pascallanger]

Yep no bootloader installed. Make sure to purchase the right FTDI which can run at 3.3v as mentionned on the github doc.

[BLeibbrand]

Hello guys, The FTDI finally arrived. I have loaded the version with the bootloader. The USB is now recognized as com25.
OpenTX is version Companion is 2.2.3 (7 jan 2019) I can only see the first two sub protocols. In the Taranis: Mode: MULT E01X E012 or E015 (no E016) Module Status V1.2.1.29 What is missing / what should I do?

[goebish]

Seems OpenTX Companion doesn't allow the selection of a custom protocol # On the transmitter, select Custom protocol, with options 45 & 2:

[BLeibbrand]

It still doesn't bind

[goebish]

I see there's a mistake in MULTI source code, here's a quick fix, in E01X_nrf24l01.ino, replace line 229: https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/04ed613ca3bd4bcda53457504adeca7aa9053168/Multiprotocol/E01X_nrf24l01.ino#L229 with XN297_WritePayload(packet, packet_length); (that will break E012 & E015, but E016H should work)

Then upload the firmware again to your module

cc @pascallanger

[BLeibbrand]

Still only blinking drone. I'm using Custom 45 & 2 Bind and bind on power up

both lines (229 and 268) changed.

Funny: If i turn the blinking drone upside down, it will blink very vast. Maybe as warning to be horizontal before binding or at least before calibrate.

[BLeibbrand]

I hope you have a next step to try.

[goebish]

Sorry, revert the change on line 268, I wasn't looking at the last version of the file, it should be if (sub_protocol == E016H)

[goebish]

Your last error in the Arduino IDE is normal

[BLeibbrand]

OK. Now it does bind. If you give it about 65% throttle the rotors spin (smilar to the spin with the standard transmitter just after binding with the throttle UP and DOWN). (After some time it does sometimes take of but I'm sure why). SF will disarm SB will blink 2x

[goebish]

I don't understand your last message, does it fly ?

[BLeibbrand]

Left and Right seem to be opposite. Yes, it does fly as soon as you move the throttle a bit down and up again like 80% to 70% and up again. The spinning only starts above the 60-70% below that no motors.

[goebish]

Ok that's normal (same as stock controller). You can reverse Aileron and/or Rudder direction in the mixer (set weights to -100%).

[BLeibbrand]

So the drone is flying. Attitude hold is good. Drifting to the right. (trim complete to the left to make it stable) Headless and Stop are working. RTH seems to fly to the right. No space for flip at this moment

[goebish]

if it drifts put it on a level surface then set both sticks to bottom corners (I don't remember which ones) to recalibrate the accelerometer. Or add some subtrim for this channel in the output screen.

[pascallanger]

E016 should be fixed. Can you download the latest version from github and try?

[BLeibbrand]

After reversing and trimming the drones is stable. The drone also has these features:

• Calibrate (normally done after the bind with both sticks in bottom corner. It does not seem to work)
• One key take off Is it possible to add these also?

[goebish]

Ok, I'll check if calibration requires an extra flag. Is one key take off really required as pushing throttle stick just does the same ?

[BLeibbrand]

One Key Take off would be fine to give new users an easy way to get the drone up without the up-down a bit - up sequence needed at this moment. So I would say: Nice to have.

Calibration seems to be needed as the trim and the strange RTH direction might be caused by it.

[BLeibbrand]

Can you see if this drone also supports other flight modes (like acro) because as you mentioned before. If you are able to fly a drone this might becomes boring when you have some flying space.

[goebish]

One key take off would be a mess to implement, and not every controller has a momentary switch, honestly that's not a big deal if you've to push throttle instead of a button (this quad is very gentle ;)) Don't expect hidden features (acro mode...) on this kind of quad, it would be too heavy for acro anyway, it would require bigger propellers and motors, that's just a machine for beginners/kids ;) I found the calibration flag, I'm implementing it.

[goebish]

@pascallanger added calibration flag: https://github.com/DeviationTX/deviation/pull/844/files

[BLeibbrand]

I have uploaded the newer version (1.2.1.30); It is not recognized in the Taranis: Mode: MULT E01X E012 or E015 (no E016) So I still use the Custom 45 & 2 I have removed the reverses as they are fixed. I only have to glue some components... The rest is for tomorrow.

[goebish]

That's normal, E016 will only appear in the menu with the next OpenTX update.

[BLeibbrand]

Funny to see my other Eachine (E010 mini) is in an other group MJQX instead of E01X.

[pascallanger]

Calibration available in the new version.
