homepage Forums Technology Flight Sim Pit Builders MMJoy/MMjoy2 - Set your own USB controller with a cheap Arduino

Joy2key is really limited to 32 buttons, I confirm there with 48 buttons controller.
Since this soft' was done for gamepads it's understandable. A pity as it is very practical.

Quick question, I'm trying to use this firmware to interface Apple ][ and Radioshack coco joysticks.

On the coco joystick pushing the button takes it to gnd (0).
On the apple joystick pressing a button takes it to +5 (1).
So since I can't use the button matrix, is there another option just to use the inputs directly?
Rewiring the joysticks isn't an option, since I'm just making a adapter to use original joysticks.

I can throw a 7404 in the circuit to swap either the apple or the coco so everything is the same either high or low.

There will be a total of 6 buttons in this design.

Thank you.

= FIXED =


when i save set to device, error message popup: "error write config.[data error(cyclic redundancy checkk} "

did I burn the card. ^^ how can i fix this.

Thanks!

Because i used different firmware and MMJOY config editor

Hi,

Just signed up to say thanks to mega_mozg_13, Sokol1 and you other helpful people for all the awesome information and software in this thread.

I have recently finished my G940 anti-hysteresis project.
This involved rewiring the G940 Throttle, rotaries, rudder and toe axes to the cheap Pro Micro I bought on eBay.
I have no prior soldering experience, so it could've been a bit tidier, but works as intended. Also no one sees it when the cover goes back on anyway.

The results are simply brilliant! The unit no longer spikes and is enjoyable to use.
This thread made is seem like a fairly simple (yet time consuming) procedure. And it was. So Thankyou!


Now, I have a few questions.

Axis names. Can they be renamed so they will show up in the Windows joy.cpl application?
For example can I have HippyX, HippyY etc.

Auto-Calibration. It seemd logical to use with the Rudder, but what exactly are the differences between Auto w/centre, Saved w/centre etc.

Dead Zone/Stopper. I tried playing with the curves in MMJOY2 to create for example a 10% dead zones at the start and ends of some of the potentiometers. But I couldn't quite achieve what I wanted here. I assume this is possible?

The manual for MMJOY? I'm guessing it would answer most of my queries. I must've missed it?


Cheers,
Hippy.

lnly shift register helps to you:
CD4021 - tested and work very good (Thrustmaster grips/Defender Cobra M5)
74HC165 - testing now...

when you reset axis names (rename, add or remove), change VID/PID to new state.

Hi! I made this. I works great, and I found a bug.








This is the bug, I wanted to add SPDT toggle switch on shift registers' CS cable, and basically double the number of switches. But when I add second shift register and only when I press switch 8 it activates all switches in second shift register.

I ended up using a cd4066 with a 7404, I had them laying around already.
Max of 4 buttons per 4066, but that's do able.

I'm using this as a interface for 1 apple joystick and 2 coco joysticks, so 4 buttons total, and I can slap another 4066 in for more buttons if needed.

Thank you for this wonderful firmware/program.

MMjoy2 + Honeywell SS495A1 HALL sensor in CH PRO Pedal.

Original pot support was used for "BIC HALL pot", with ball bearing in axis. R/C Helicopter ball-join in connections with fiber glass push rod.

The switch for reset MMjoy2 is accessible on the underside of the pedal by inserting a pin.

Hi guys.
I would like to use ATMEGA32U4 to make a RPM Gauge. I have searched Google but no luck. Does any here got information or link related to how to use ATMEGA32U4 to make a Gauge? Thanks a lot.



FOUND : https://www.arduino.cc/en/Guide/Introduction

I have plans to do this with mini servo:
(russian forum) http://forum.warthunder.ru/index.php?/topic/159447-virtualnaia-pribornaia-panel/?p=4943442

I want to do that, but dont know how to

if you want back to live real devices:
www.letiaga.ru
www.avsim.su #1
www.avsim.su #2

Those gauge is not "real device" (maybe the cover is "real"), but inside is use a piece of PRO-MICRO-ATMEGA32U4 and stepper motor.

For a WW2 simmer, MMJoy2 with RC model servo or stepper control would be heaven

indeed, but i even dont know how to connect stepper to my little Pro Micro ATmega32U4 yet. Hard to find informatio on line.

Mega_mozg, can you add saturation?

please tell me more details about this, or show working sample.

In Diview there is calibration, dead zone and satutation
