Update: MMjoy2 USB 2.0

What is MMjoy2?

A free firmware developed by Mega_Mozg13 for make USB joystick controller using specific versions of Arduino/Teensy prototype boards, without need to assembly circuit boards or write computer code or deal with Arduino "sketches".

Solder tools and skill is need to assembly pins in some Arduino boards, as well to attach potentiometer, sensor, buttons as in any joystick.

Hardware needed: ~5$ Arduino PRO Micro (ATMEGA32U4) clone (or ~20$ Sparkfun/Teensy versions). Other supported boards linked bellow. Sample:



IMPORTANT - Arduino PRO MICRO with ATMEGA43u4, 16 MHZ, 5V.

Firmware : MMjoy2 - is loaded in Arduino board through a USB cable with MMJoy2 JoySetup software:

Tutorial for firmware upload - by Geneb(F15SIM): http://www.geneb.org/mmjoy2/pro-micro-instructions.pdf

Sample of firmware upload, using Teensy 2.0+: http://forum.il2sturmovik.com/topic/18379-teensy-20-mmjoy2-firmware-joystick-controller

Features (latest firmware):

Buttons: Up to 128 - Notice that 128 buttons was possible in some boards only due pinout limitations, see in links bellow.
Buttons connection require use of Diode Matrix or Shift Register circuits. Sample o DIY Shift Register board, by Debolesis (ED forum).

Encoder - up to 6, adjustable "click" times

Axis: Up to 8 axis using the internal 10 bits (1024 points) ADC or up to 8 axis using 12 bits (4096 position) using external ADC MCP3201, 3202, 3204, 3208 (the last digit indicates supported axis number)

Inputs (axis) in analog mode:

Conventional potentiometer, Linear type (B code), 1k to 100k, ideally use 10k.

HALL sensor: Radiometric linear, example Honeywell SS495A1, Allegro A1324

Inputs in digital mode:

TLE5010/5011, KMA200, KMZ60 + MCP3202 magnetic resistence sensors.

* TLE5010/11 has internal ADC 14 bits.

8 way PoV HAT.

Special functions:

- "Shift" (mode) function, allow a physical button press a virtual button if "shift" are ON.
- Compatibility with shift registers used in F-22 PRO, Cougar, Warthog and Cobra M-5 grips, making use this grips "plug-and-play".
- "Joystick" name, VID, PID defined be user as desired, allowing use several MMjoy2 in the same computer.

If you want configure MMJoy as "2 axis and 1(or 0) button joystick" you can.

Update December 2015:



Compatible Arduino boards - should use ATMEGA32u4, ST90USB646, ST90USB1286 m/c (16 MHZ, 5V):

Skip the DIY build boards part (first posts - like here) with today available and cheap Arduino boards the DIY ones became obsolete.

IMPORTANT:

Flash the firmware in the Arduino don't create a ready to use josytick controller, but a blank template with 0 axis, 0 buttons:



For you customize like your needs defining number of axes: 0 to 8 axes, number of buttons: 0 do 128 buttons, joystick name, VID/PID... use MMJoySetup program, filing the options and after "Save sets to Device".
===============================================================================================================

WARNING (02/20/2017): Is know that MMJoySetup - the firmware flash, configuration utility - don't run in Windows in Chinese language, and virtual machine running English Windows don't help - the COM port is not seem.
In that cases is need a computer/laptop running a Windows in English, German or Russian for run MMjoySetup.

Original topic about MMjoy -now obsolete:



Sokol1

If you want to use the Teensy++ 2.0 board, you can use GenericHID: http://generichid.sourceforge.net/

g.

Gene,

I know some other firmware for use Arduino (like Teensy) boards as joystick controller.
But since MMjoy do the same and more, is configurable, and develop by simmers is (my)
natural choince..

Sokol1

Sokol, what do you do to keep the noise down? I had my Teensy3/Arudino Uno hooked up my supposedly high quality pots, but the outputs jitter... They don't show any jitters with BU0836x or UHID.

Does MMJoy use some special filters? Better, if there is a way to port it over to Teensy/Arduino...

I dont have experience with Teensy, only with Mjoy DIY boards (~8), with pots have no jitter, and some with HALL sensor, is need use shielded cables.

AFAIK - MMjoy firmware are ported for Teensy 2.0 - is just matter or write via USB ISP cable - but not for 3.0

Sokol1

Hi to all. I'm author of software/firmware MMJOY.


Firmware have software filtration algorithms. Have 15 steps of filtration settings.
"Filter #1" - no filtration, clear signal from sensor;
"Filter #15" - maximum filtration;


Any questions and(or) ideas are welcome!

Hi Mega, thanks for the reply! Is the filter function an average of multiple analog reads? Can the algorithm looked up somewhere? I'd like to implement my filter code for my Teensy3...

Look here: https://code.google.com/p/mmjoy/source/browse/
Folder: common_libs
File: MMJoy.c
Function: Axis_Filter()

PS: All project materials are open source.

Yep got it! Thanks! Will look through it tonight!

Does the firmware work with the Teensy++ 2.0?

g.

Not now.
But possible in future, need only a sample "Teensy++ 2.0".

I asked about the Teensy++2.0 because of the work this guy has done:
http://generichid.sourceforge.net/

The extra pins on the ++ would benefit MMJoy I think.

g.

MMJoy main idea is a simple controller for a simple joystick.
I don't want make 'fat cockpit controller' with hundreds buttons/axis/indicators.

About 'Teensy++ 2.0' I asked developers for sample/discount items, and was refused.

Hi, I have bought a Leonardo Pro Micro clone because I want to build a collective for DCS-UH1. It is detected in Windows as Arduino Leonardo and HID device, however in MMJoy-Loader it doesn´t show in the device list. I installed the driver from the JoyLoader_arduino folder, do I have to do something else before using the loader?

1) for first time - manual select from the list 'Scheme'
2) select firmware(hex) file
3) manual input COM port of Arduino.
4) click 'upload...'

Ok, thanks for your help. Now I receive a message about missing libusb0.dll. Where can I download it?

It is a part of Atmel FLIP:
FLIP 3.4.7 for Windows (Java Runtime Environement included)
After install look in Flip\usb\...

Well, still having no luck with my board. I get this message:

Connecting to programmer: .
Found programmer: Id = "¤ ""; type = &#9786;
Software Version = . ; Hardware Version = .
avrdude.exe: error: buffered memory access not supported. Maybe it isn't

Presione una tecla para continuar . . .

Any idea?

let me know one thing.
When device start bootloader on console "device management" you see "COMx port" (where 'x' maybe variable) or "ATMEGA32U4" device?(make screenshots please)

Ok, I see my mistake, I did not tried to launch Joyloader while in bootloader mode (a little difficult, you only have a few seconds after manually restarting the device). Working OK now.
I have one more question: How does the buttons matrix work ? Is it similar to Leo Bodnar's BU0836?
Thanks for your help.
