Ersky9x without telemetry using Flysky protocol By Chance I found the reason why one of my models was permanently telling me "No Telemetry" When the Telemetry Usr Protocol is set to HUBRAW the radio permanently, with maximum repetitionrate, tells you that there is no telemetry This Bug is there sinc...

Some time ago I got a Multiplex Cockpit SX transmitter with defective electronics. As the mechanics of that transmitter are really good, I was hoping to rebuild the required electronics in the way of the ER9x. I didn't want to have the voice module or a trainer connector as the original radio had it...

regarding to intermittend compile errors with the Arduino IDE There is/ or was? a problem with the linker (at least until the version 1.8.0 that I still use). I had the problem that least modifications of a file, e.g. adding a line of code or even deleting a commentline could lead to a "load error 1...

Thanks Mike

SInce the Git updates of 2019-07-30 the status of the IDx switch is shown on the system page that shows the status of hardware and logic switches. That shifted all the following LSx switches one position to the end, thereby loosing the last logic switch LI from the last subview. The TRN switch displ...

Thank you, Mike

Reinhard

That delay is still there, exactly as with your original programming.

In your programming, you use three logic switches (L6, L7 and LA) that can be replaced with a single one (LB in my example) that has the same functionality. Just another way of programming for the same thing.

I downloaded the github code from 2019-11-27 and there are some problems. ErskyTx: Compile error with AR9x/9XRpro ==================== Compile parameters: make REVB=1 STAMP=1 DEBUG=1 REV=222 USER=ReSt menus.cpp: In function 'void menuProcIndex(uint8_t)': menus.cpp:24513:28: error: 'BtStatus' was not...

I had a look into your file and here are some comments You can get the function of the three switches L8,L9,LA with a single switch of |v| > val Rud 96 ( |v| means absolut value of v, gives always a positiv value for v from -100 to +100) You probably connect Switches to Ch7 and Ch8 to power on/off t...

If I remember correctly, it was said, the files are displayed in the sequence, they have been written onto the card.

Reinhard

Have a look at this thread

viewtopic.php?f=5&t=12296#p146899

(I don't know the sense of the flight controller in your configuration)
Maybe it gives you an idea of how to do what you want.

@pstimpel: The solution given above can slow the inner motor down to 0. Here comes a more advanced setup that can drive the inner motor to full reverse speed. This is what I have for a 2 motor ship, but in the endeffect does the same for a bagger or a tank. But in the moment this setup is for a mode...

Try the following: CH01 -100% RUD * +100% THR (This is a multiply mix!!) +100% THR Curve(c9) CH02 +100% RUD * +100% THR (This is a multiply mix!!) +100% THR Curve(c9) Curve C9 100, 67, 33, 0,0,0,-33, -67, -100 The curve is not required, but gives you a wide dead zone around neutral, so that both mot...

one first trial could be:load the V-tail template.

Reinhard

Reversing a direction is either done in the limits menu (NOR/INV) or in a mix by changing the sign of an amount e.g. +100% => -100%

I installed this code

You could try flashing "ersky9xs_rom.bin" (the "small" version for the SKY board).

AND IT WORKED !!!

Thanks Mike,

Reinhard

But this is the second option.. (When we hold the trimms, just opposite than firmware update)

No, that didn't work either.

It was absolutely stuck in the "flash firmware" loop.

Reinhard

Thanks Mike, I will try that and report back. In the meantime, in the intent to narrow down the problem I flashed the AR9x bootloader 3.2 onto one of my two 9XR-Pro's And now the 9xr-Pro has that same problem of looping . But with the difference, that I'm not able to anymore get into the maintenance...

I used the same source code and compiled it for the 9XR-Pro.
And then updated the bootloader from that firmware file. The resultant bootloader on the 9XR-Pro was version 3.0. versus 3.2 on the AR9x.
And the 9XR-Pro had no problem with it.
Either version 3.2 or/and the AR9x has the problem.

Reinhard

Not in a hurry.
As long as bootloader 2.9 does its job, there is no problem.

Reinhard

I just ran into the following problem. Yesterday I downloaded the latest code from github and compiled it for 9XR Pro and for the AR9x board. So far everything ok. Firmware is running. I recognized, that the AR9x had a bootloader version 2.9 so I flashed the bootloader from my actual fw image. It th...

Thanks for the answer, Mike. I'm trying to revive a multiplex Cockpit SX transmitter with a dead mainboard. It has a built in scroll switch that I will try to use. But for ease of handling its probably the safest way, if I can manage to have a 5-way tactile switch in addition to the existing scroll ...

With a basic 9x radio (with M128) , when using a simple scroll switch (scrolling plus one single switch) like this one https://openrcforums.com/forum/download ... &mode=view
is it possible to handle all menues or do I need additional switches ?

Reinhard

Yes, that is the correct one.

And... Chip-Quik is a really good thing for removing the old chip.

Reinhard

At least use an M128A (that's even cheaper than the M64)

Reinhard

If you use the stock rf module, maybe this picture can help you to check the voltages.
There is one more regulator (3.3V) on the rf board

In the mixer setup there is the "Multiplex" selection with "ADD", "Multiply" and "Replace"

Select "Replace" and it will show the line with ":=" instead of "+="

Reinhard

These two mixes must be of type "Replace", not "ADD"
+= 100 Ail L02
+= -100 Ail L03

Edit your er9x.hex file with a simple editor e.g. "Write" and verify the two lines I pasted in the above post.
Only to verify, if your file is the same as ours (at least at that position of the file).

Reinhard

I would download the code again. The error message says, avrdude detected a CRC error in line 1374 of er9x.hex (the last byte in a line is the CRC check byte of the databytes of that line) 1374 is hex 55E so either the line that starts with :1055D or the next line :1055E should be the line that forc...

I'm getting some compile errors for AR9x and 9XRpro with the latest download. File sTxsplash.lbm is missing (rename the s9xsplash.lbm as a fix) In the "Makefile" I had to remove line 878 ("pxx2.cpp \") (There is no pxx2.cpp file in my download). After that, it compiled without any further problems R...
