RGB Backlight and Rotary encoder

[jhsa]

I would like to know if the RGB backlight has the same size as the hobbyking backlight we normally install in the 9x radio. The reason I'm asking is because I have a 7 way rotary encoder installed on the radio that will receive the 9Xtreme, And want to make sure everything fit.

Thanks

João

I'm not sure if this will help. But here is a picture of the components together. I have already installed everything so unfortunately I cannot measure for you. But what I can tell you is that it fits snugly behind the screen. Just by looking at the picture in hobbyking site, I would say the 9xtreme backlight have a longer width. (vertical)

[jhsa]

Thanks..
The HK backlight rests already on the side of the encoder when installed..

9Xtreme b/light is 82*51 mm. I don't know HK size. I wasn't copying them, I just made it the "right" size by my determination. Admittedly, I wasn't considering interference from a rotary encoder. The backlight really is just a hunk of plastic, other than the thin tiny circuit board on one long edge. So you may be able to machine it to accomodate?

[tedbmoss]

Re: size of backlight. 51mm is small; 52mm is large.

This can be moved around a bit, without causing a problem with the lighting.

Don't forget to change the pad on the back of the x9 motherboard, if you have the original, it is too thick and Steve has supplied a thinner one because of the thickness of the added backlight.

Do not cut the board down to minimum size, it will cause dimming on the edges of the display.

Thanks for the pic.. the 9xtreme's BL is actually a little shorter in length and that is good. I had to dremel a bit of the encoder's PCB so the HK backlight would fit. By being 2mm shortt it might fit better

[s_mack]

Ehem, yeah.... like I said. .. I thought of everything, including the rotary encoder.

[MikeB]

The HK backlight doesn't fit well between the 'posts' for the screws for the PCB. The 9Xtreme RGB backlight does fit between these.

Mike.

[jhsa]

Due to being 2mm shorter I believe..
Steven thought of everything of course

Thanks

How do we connect a rotary encoder with the 9xtreme ?

[willhac]

Anyone can help ?
I'd like to to the rotary encoder mod, with 9xtreme, does it have pads to connect encoder to ?
Or do we connect the encoder as before without the 9xtreme ?
Thanks

[MikeB]

At present, if you connect the encoder to the original board, on the LCD data lines, this should work. The firmware flashed to the M64/128/2561 should relay the encoder position and switch to the 9Xtreme.
I did test this by flashing a 9X that has the encoder fitted, and connecting to it with wires from the prototype 9Xtreme, but I haven't got an encoder on the 9X I have the production 9Xtreme in.

I also have another possibility in progress. This uses a 3.3V Arduino mini connected to the 9Xtreme using the I2C connection. The Arduino handles the encoder and passes the position to the 9Xtreme. The Arduino could also handle some extra inputs/outputs. I tested the encoder operation using a 9XR-PRO over I2C and it worked fine.
I have only just got an I2C driver working on the 9Xtreme (not a very good one but it works), so I haven't got this working on the 9Xtreme yet.

Mike.

[jhsa]

You are full of surprises Mike I thought you had discarded the arduino option.. Thank you.

João

[MikeB]

No, just not had time to progress it much. I need to improve the I2C driver code really if it is to be used for an encoder. I also only recently got a 3.3V arduino mini to try for this.

In many cases a normal 5V arduino can work at 3.3V level.. One example is the multiprotocol DIY RF module.. I built one using a normal 5V arduino but fed 3.3V on the VCC pin. It works well..

João

[MikeB]

It may work, but as an electronic designer, it is being operated out of spec. This means some people using it will find it doesn't work when it get hot or cold, and if the 3.3V is, perhaps, on the low side.

When I tested by using a 5V Arduino, I used the clock divide by 2 option so it was running at 8MHz, although the oscillator was still running at 16 MHz.

Mike.

[willhac]

Ok it' clear to me now about the encoder , so the arduino will also provide additional switch inputs for example ?
Until now I have ELE as 3 pos on PG5, and PB1-PB2 on PC0-PG2, do I have to remove them for the moment ?

Mike.

well, I don't have any 3.3V arduino, so I guess we will have to find out, right?
Cold will be widely available in the area I live.. so we can test that..

João

EDIT: I also have arduinos with a "Real" Xtal (not ressonator), and I think I do have some 8Mhz crystals. So, maybe I could just change it and flash the right arduino bootloader. Would this work?

Those inputs to the M64/128 won't be passed to the 9Xtreme.

In the hardware menu, on the 9Xtreme, there are 8 EXT options for extra switches. These use the 8 trim switch inputs on the original mainboard. I'm using one of them to make my ELE switch into a 3-pos switch.
These are on the 9-way connectors, pins 5, 6, 7 and 9.

How do we connect a rotary encoder with the 9xtreme ?

I've just been testing a 3.3V arduino mini with a rotary encoder attached and connected to the 9Xtreme over the I2C bus. This seems to be working fine. It only supports the encoder so far, no other connections.
The next test version of the 9Xtreme ersky9x will include this support.
This is the code I'm curently using on the Arduino (3.3V, 8MHz):

Thanks Mike.. would it be possible to test this on the 16Mhz pro mini running at 3.3V? To see if it works? I don't have any 8Mhz arduino and ordering now will take a month to arrive

Also, if my 9x already has the encoder connected to the m128, can I just leave it like that, or do I have to move it to the arduino?

Thank you

João

[MikeB]

Look in the .ino file. You will find 3 lines commented out in setup(). These switch the 16MHz for a standard 5V mini down to a clock of 8MHz, so only the oscillator is still running too fast!
I tested on a 'PRO with that version first.

If you already have an encoder on the 9X, it should just work with the 9Xtreme.

Thanks Mike.. it's great that we can also use an 16Mhz arduino.
Also great that I can use the current encoder connections.
Are you planning to implement this on the other boards? As you say you tested it on the pro, and I have another ersky9x radio that still doesn't have an encoder installed, and I could test this setup using it.
Thanks
João

[willhac]

Yes, thanks for this new feature Mike.
Just received a new 9x TX, with micro SD & CR1220 today !
Connected 9Xtreme, all went well.
I'll connect the encoder to the LCD lines first, as I don't have a arduino (yet).
Will this be the first radio with 3 microcontrollers ?

[willhac]

At present, if you connect the encoder to the original board, on the LCD data lines, this should work. The firmware flashed to the M64/128/2561 should relay the encoder position and switch to the 9Xtreme.

It's working perfectly, thanks.

[tedbmoss]

Is there a rotary encoder pc board? How is the install done in the TX?
Thanks in advance for your answer.

[willhac]

You will find a lot of info here for the install :

Hi Mike, im trying to flash this software to pro mini 168 - 3.3v, but the following error shows up:

I haven't tried Arduino IDE 1.6.12.

Mike.

Is there any other software i can use for flashing this file to arduino?
