an Arduino USB HID controller, composite USB controller

dubalucu · September 22, 2015

hello overpro, thanks for your work :D

I followed everything, and the computer recognized the arduino as 2 game controller. I started to test with a button. I thought I just need to connect a collum and a row by a wire and the buttion should be on, I am right ? There no light on the game controller test

One more question: Is that true that we must use the 1N4148 diode ?

Thanks :)

i think you are right, but my 2560 havn't login in DFU mode, so i havnt test it yet.

i just pruchased USBISP for bootloader on my 2560.

Hi dubalucu,

In reply to your post # 127:

Initially I thought you might have gone out of range on the Windows Game Controller window (which will show buttons for each CVP Joystick but only upto # 32). But when I connected your particular combination of pin #31 and pin # 39, I got a light on the second CVP Joystick, button # 18. This was visible in both Windows Game Controller and SVP Mapper.

Of course, I am using diodes, but I think you should be okay without it if you're testing just a single pair of pins (single button).

Please correct me if I am wrong.

CK.

For start , Thanks for your work overpro ;-)

I wanted to know if there are a simple possibility to include led control ?
The idea is to light on a led when you push a momentary switch and and light off when you push it a second time ( for know the state of the command you push).

for information, i start to make a front panel of my homemade play seat for Star citizen.

Thanks for your answer.

This might be a little bit complex, to achieve the effect you described the USB device firmware need to implement an OUTPUT endpoint so the device can receive data from an application running on the PC.

Write this application is not straight forward.

To control a single LED on or off there are 2 approaches, use a max7219 or use the scan matrix.

This is exactly what im looking for.

I was looking for an inputmodul, which gives me really much buttons as Joystick for the PC.

So without the timelimited pins i have calculated about 192 usable buttons.
I am building a Pad, which has 100 Buttons, needed for Star Citizen.

So my question:
Is there any way to use pin 2 - 21 and pin 54 - 69 for LEDs if Joystick button 32 upwards are toggled, to light those LEDs?

Just for visual information, to know Gear is down or Hatch is open or something like this.
Because the first buttons wont work as buttons, they are just for toggle-switches, which i dont need.

And Pins 54 - 69 are those Analog-Inputs, which can be used to digital outputs, too. I dont need any analogue axes.

http://forums.eagle.ru/showpost.php?p=2480775&postcount=130

some of the pin from Pin 2-21 can be used as digital output pins so they can be used as the LED scan matrix pin.

But if you want to use this board to control the LED there are more works to do: writing an application running on PC and extract and send StarCitizen's data to this USB device through USB protocal.

You can use the wire to test the button, but note that the first 4 rows (pin 22~25) are reserved for rotary encoders, so use pin 26 instead.

You have to use joysticktest: http://www.planetpointy.co.uk/download/5/

because windows default joystick tool only shows the first 32 buttons.

Stiff · October 11, 2015

I really appreciate this job, it works really good with my project! Thanks Overpro. I tested the Analogs and they worked, the buttons work ok too. Didn't tested the rotary encoders yet

But i had a crazy idea.. would it be possible to use an old mouse (the PS2 ball mouse) as a rotary encoder? The ball mouse works with an arduino, but i don't know if it would with this Project

Also, it's possible to use at the same time the axis and the rotary encoders?

Thanks

tomahawk66 · October 11, 2015

Hi Overpro,

Thank you ever so much for your fantastic contribution. I have successfully tested your code with encoders and switches in FSX, and everything works as intended.

Now, if one uses FSUIPC LUA one can actually access upto 256 inputs per HID controller. This would be a better solution for FSX-FSUIPC (rather than the present 128 x 2) as then there would be no possibility of the software wrongly identifying the joystick involved (as might happen now with 2 joysticks labelled cvp joystick).

So my question is whether there is a simple way of modifying your code to achieve this? As I am not an expert programmer, would you or anyone else be willing to do this and offer this as an alternative?

Thank you once again!

As the Mega is shown as 2 Joysticks, I'd like to know, which pins correspond to each joystick. My guess:

Joy1 -> row: 22-29, column: 38-45

Joy2 -> row: 30-37, column: 46-53

So all encoder-pins would then be on Joystick1. Is that correct?

tomahawk66 · October 11, 2015

@RightStuff,

I had the same question, so after some experimentation, was able to draw up the following scheme and 'formulae':

Mega2560 R3, digital pin 22 ~ 37 connected to row 1 ~ row 16

digital pin 38~53 connected to column 1 ~ column 16

(please note I use 1 ~ 16 rather than 0 ~ 15)

Scheme: rows (1 to 16) x cols (1 to 16) = 256 points

cvp1 = first cvp joystick in svp mapper / pointy joystick test

cvp2 = second cvp joystick in svp mapper / pointy joystick test

ENCODER: row used for common connection, column used for diode connection

BUTTON: row used for straight (= non-diode) connection, column used for diode connection

rows (1 to 4) x cols (1+2 to 15+16) reserved for encoder_buttons [1+2 to 63+64]

rows (5 to 16) x cols (1 to 16) reserved for button [65 to 256], or, button [65 to 128, 1 to 128]

_____________________________________________________

row 1 col 1+2: cvp1.encoder_buttons 1+2

row 1 col 3+4: cvp1.encoder_buttons 3+4

.

row 1 col 15+16: cvp1.encoder_buttons 15+16

row 2 col 1+2: cvp1.encoder_buttons 17+18

.

row 4 col 15+16; cvp1.encoder_buttons 63+64

formula is cvp1.encoder_buttons [16*(row-1) + col]

-----------------------------------------------------

row 5 col 1: cvp1.button 65

row 5 col 2: cvp1.button 66

.

row 5 col 16: cvp1.button 80

row 6 col 1: cvp1.button 81

row 6 col 2: cvp1.button 82

.

row 8 col 16: cvp1.button 128

formula is cvp1.button [16*(row-1) + col]

-----------------------------------------------------

row 9 col 1: cvp2.button 1

row 9 col 2: cvp2.button 2

.

row 9 col 16: cvp2.button 16

row 10 col 1: cvp2.button 17

row 10 col 2: cvp2.button 18

.

row 16 col 16: cvp2.button 128

formula is cvp2.button [16*(row-9) + col]

Hi Stiff, I think you can have a try on the ball mouse, If the ball mouse works like an encoders it should works here as well, please let us know your test result.

Yes it's possible and actually my first implementation is a single joystick with 256 keys, BUT... there are some compatibility issues with other software, such as Team Speak, if a HID controller has more then 128 buttons the TS3 client will crash ( no exception ). So I changed it as a composite USB device with 128 buttons on each joystick.

Change it back to 1 joystick with 256 buttons are not complex for now, but still requires some work. I can provide a 1HID*256buttons version later.

Your C.V.P joystick code is very cool!

I became interested in Arduino with your code.

I believe that there are endless possibilities in Arduino

So. It is thanks to you who always realize it.

But Your C.V.P joystick code is not easy to have to learn.

You said~

“ps. this firmware is inspired by Darran's project: Arduino UNO Big joystick HID firmware:

http://hunt.net.nz/users/darran/weblog/15f92/

with out Darran's code I will never make this work. Thanks Darran.“

If you help me, I would like to receive your inspiration.

Above all, I thank for giving an answer from your busy day.

I also want to do this to start.

1. I had been download the files to this website.

“Big Joystick Firmware”, “riclamer_big_joystik.ino”, “Arduino-big-joystick.c”, “Arduino-big-joystick.h”, “Descriptors.c”, “Descriptors.h”

2. I have Changed to “riclamer_big_joystik.ino”, as shown below

But I found some problems.

1) I dont know why starting from joystick button No 18, 19~~28.

Thank you again for your wonderful work!:thumbup:
Warm Regards....

Here is the firmware for 1HID interface with 256 buttons,

no changes on arduino code, only atmega16u2 firmware has changed.

Please have a try.

Note that some joystick testers will not work:

1) Pointy's Joystick Test can't detect any key press,

2) xplane can detect press if key ID <= 128

But I'm sure the HID report is correct.

Hi overpro,

Thank you so much for this .... quite fantastic! :thumbup:

I loaded the new hex file (needed to short the pins before Flip could open the USB port) ..... and yes, pointy's joystick test does not work ..... but, SV Mapper duly showed a single C.V.P Joystick with 256 buttons. .......

However, from the image, you will notice that many buttons from 225 to 255 seem to be permanently on, even with nothing connected to the Mega pins.

On testing the pins with encoders and switches connected, I found normal responses from Mega pins (22, 38+39) = encoder buttons [1+2] all the way to pins (29, 53) = button [128]. But there was no response to Mega pins [30, 38] onwards.

So it seems that the present firmware/code will recognise a joystick with 256 buttons but will not respond to button presses beyond # 128 (or beyond Mega pins (29,53)).

Thank you for your attention, and with Warm Regards!:)

Hi OverPro,

I tried to make the ball mouse work but i can't, i think i should buy a RotaryEncoder.

But, is it possible to use the Rotarys and the Analogs at the same time? It would be really useful because I am doing a Steering Wheel (like a Logitech g25) and I need the Rotarys and the Analogs to work at the same time, because the Potentiometer in the Steering is 270º only and it sucks for some games...

We can't use rotary encoder on the analog input pins. So if you want to do a wheel and steering like 720º then you need to put some geers between your wheel and the poentiometers. The geer should transform the 0~720º motion to 0~270º

Hi Chakko,

I suspect SV Mapper doesn't recognize the button press correctly, I used Microsoft Message Analyzer - MMA to capture the USb device HID packages and I can see the HID report is correct.

Attached is the screen capture, the lower right window is the HID Input report, as you can see we have 48 bytes, the first 16 bytes are the 8 axis, the 17~32 bytes are the button value for Pin 22~29,

the 33~48 bytes are the button value for Pin 30~37.

I shortcut the pin30 and pin38, so byte 33's value is 0x01. And all else are 0 which means no button were pressed.

I'm thinking it might be better to test it under FSUIPC directly.

Or you can use MMA to test your button directly. Please watch the 2 video tutorial first, the MMA GUI is not that straightforward as I expected.

Overpro,

Two questions.

1. How are the progress of row 4, 5 used to support 16 On - off - On toggle switches ?

2. Could you make for us a sketch for 6x6 Arduino Uno ?

overpro · October 19, 2015

1. How are the progress of row 4, 5 used to support 16 On - off - On toggle switches ?

Actually I have finished this part but I haven't push the arduino/firmware code to github yet, because this change might affect some people's cockpit.

It's not using row 4,5 but row 15 instead ( pin 37 ) as the OnOffOn toggle switch, so you can connect 8 toggle switches. Connect the middle pin on the switch to row15 ( pin37 ) and 2 other pins to col0/1 col2/3 ... col14/15.

The 8 OnOffOn switch will occupy 24 button bits in the HID report ( 8 switches * 3 bit per switch ).

As 16 pins are used and 24bit data generated, it must borrow one byte from the normal buttons, so col 8~ 15 on row 14 will be used for the OnOffOn button. Don't connect any switches to this section.

Now the normal button count is 16 * 10 + 8 = 168, which used 168 bits

8 OnOffOn switches used 24 bits,

32 rotary encoders used 64 bits.

If you want to have some test I can provide a dedicated arduino/firmware here.

This is definitely possible, let me get a uno board first.
