LOL!

Thanks again!

Shame on me! How could I forget?! :( Thanks, this certainly helped! It's not the first time I swap the MCU on the AR9x / ARUni, but this time I completely forgot about that last step... I guess this means I need some sleep! :) Now, I need to swap the chip back and see if the original one had the sam...

Dear All, I got an ARUni board that 'almost' doesn't work. Previous owner tried to install it into his radio, and he couldn't get it to work - so he gave it to me. I'm now trying to test it in its minimal configuration with just the screen, battery, power switch and a USB cable connected. When I swi...

This is another excellent thread! THANK YOU! to Sir Technicus Genius for another great hint to diagnose and fix things quickly and easily! I was asked for help to repair a 9XR PRO which stopped working after the RF module connector got somewhat short... Yes, it was the R9 that failed. All other part...

It's a known fact that 9x and 9XR gimbals are not the same and cannot be swapped easily.

Ah, sorry about that! Looks like only my local shops call this connector an 'MW-3M'. Other shops call them differently, and there doesn't seem to be a common name. Here is a link to the one at DigiKey: https://www.digikey.com/product-detail/en/jst-sales-america-inc/B3B-PH-K-S(LF)(SN)/455-1705-ND/926...

Thanks a lot, Mike!

I can't seem to find any source for these (ebay / aliexpress are of no help, either). Do you know of any replacement that could fit? Or maybe a store that offers the AM5521C itself (preferably in quantities of less than a reel...)?

A Horus owner accidentally shorted positive and negative pins in the Futaba tTrainer connector. As he says, there is a full battery voltage there. After this, his Horus doesn't power on with the power button at all. He says the radio does power on when he unplugs and plugs the battery in again. When...

Hmm.. That's an interesting question.
I don't know how this can be done in OpenTX.

Ah, so it's supposed to just limit the amount of options a pilot could choose. I don't see much use for it on er9x / OpenTX, as we can achieve the same by configuring the radio. And I'm not sure there are many people out there using the S-series receivers on non-er9x / non-opentx radios (if there ar...

Hi Mike, Did you see the "Simple mode" firmware for the S6R? https://www.rcgroups.com/forums/showpost.php?p=37665221&postcount=3095 Looks like they added three levels of "pilot skills", allowing different stabilization options. Honestly speaking, I don't understand how this n...

As Kilrah said, XM / XM+ do not have telemetry. Though, they do transmit RSSI on Channel 16 (or on Channel 8, if you install corresponding firmware). The RSSI value has to be processed by the flight controller and then can be shown on the OSD (if you have an FPV system). There's no way (that I know ...

I've been looking at the compatibility of the BF script. One problem I see is it uses the specific Taranis buttons, so trying to run this on a 9X/9XR machine will require some re-writing. A second problem is it uses "small text" which ersky9x doesn't have. I also note it writes text "...

Tssss!
That's what I suggested to JK already!

As I understand, both ar9x and aruni in their current configuration have a limited amount of RAM. The upgraded MCU is meant to solve this. JK needs to decide which one to go with for the next revision of ARUni. My suggestion is to go with a more powerful version, since it will allow more flexibility...

I'm checking with JK regarding the use of ATSAM4SD32CA-AU in the future ARUni revisions...

Mike,

This is not urgent for me at all. I don't expect to have much time for real flights over the next weeks.
Though, I still have evenings to do some bench testing, if you need my help.

Thanks!

These are the scripts I tried: https://github.com/betaflight/betaflight-tx-lua-scripts/releases/download/v0.3/BFSetup-X7-v0.3-0-g4cd7539.zip There are two subfolders ('BF' and 'TELEMETRY'). Ersky9x doesn't see subfolders in the 'SCRIPTS' folder, so I had to copy all the lua files to 'SCRIPTS' (this ...

I'm not sure whether I can reuse OpenTX scripts "as is", or I should apply some modifications first... I tried running unmodified BetaFlight scripts for X7 on my AR9x (still with a stock MCU) and the radio restarts as soon as I long-press "Menu" on a .lua file.

Some months (probably about a year) ago I had an issue with an FrSky XJT bought at Aloft. I sent an e-mail with a question, and got no response for a day or two. So I resent my question again and got a real fast reply from David Chernus. The response contained a good suggestion to troubleshoot the i...

Looking at the M4 core MCUs from Atmel, these seem like interesting options: ATSAM4S8CA-AU (512kB FLASH, 128kB SRAM) - already supported by ersky9x ATSAM4SA16CA-AU (1Mb FLASH, 160kB SRAM, 2kB HCACHE) - not yet supported / tested ATSAM4SD32CA-AU (2x1Mb FLASH, 160kB SRAM, 2kB HCACHE) - not yet support...

In my opinion, replacing a slide switch with a push button doesn't make much difference. The real advantage the new board may have is the RF Power Switch on-board. Though, it's only useful to those having an internal RF module installed. P.S. I don't have a Q X7 now... Next time I get my hands on it...

Anyone using an RF module from a DX5e with ersky9x?
There's someone on a Russian forum asking for help, as he cannot get it to work with an ARUni (as neither internal, nor external module).

The FrSky Q X7 has a push button. You push it quickly, and the radio powers up. You push and hold it for a few seconds, and the radio powers down. On the X7 it is integrated into the main MCU. So that when the radio is ON and you push the power button, there are dots appearing on the screen, one by ...

I think there should be enough space to put a stock connector at the bottom of the board - similarly to how I did it on mine. This way it will be both, nice and functional! :) Regarding mosfets, that's why I left the positive and negative poles on the switch. I know, I know, I'm the one who said it'...

Don't worry, I can always make it for you, if you wish!

Yeah, that's nice! That's exactly why I made these slots on my board: http://www.rccube.ru/image/cache/catalog/products/new_switch_1.4_02-500x500.jpg If someone doesn't use a stock beeper, he can easily cut (or just break) the unused part of the switch board and free up some space for a larger speak...

I don't think I could swap those chips myself. I just don't have the right tools :( I thought you did that already... didn't you?! I think I posted some photos of how I did that with just a soldering iron. Not much tools are needed, actually. But it does take some time (and a good flux) to get it r...

Mike, Does ATSAM4SA16CA-AU (1Mb FLASH, 160kB RAM) make any sense within foreseeable future for our application? In my local store, these are sold even a little cheaper (about $9) than the ATSAM4S8CA-AU (about $13). Neither of these are in stock though, so I'll have to place an order and wait a few w...

andrewju: Definitely too early for that! Is there a LUA for openTx that does that I could look at to see what needs to be implemented for it? Here are several LUAs for OpenTX (I guess the main difference between them is the UI adaptation for different screens). It would be great to have this workin...
