Programming leads

[ridgerunner]

I have a quantum rival I am bulding one ,iam in a rival does fair I need to reprogram it and put bigger tires on it ,I am a very active,give me some advice . ridgerunner

[ridgerunner]

thanks I will try to get program

Q-logic or NE joystick.?

https://www.southwestmedical.com/replac ... r-controls

Both require 1314 PC Software .... the NE programs via a serial cable the Q-logic via a CANBUS interface.

Woody, can you PM me a price for another rc interface for the invacare (5v joystick) chair? Thanks!

[woodygb]

Unfortunately I have no idea what's inside the Invacare joystick ...so I cannot make one ( or decide if it's possible ) ... without access to a complete system.

[Burgerman]

Oh. Presumed just same analog output joystick. Invacare says v5. I can measure? Once it (attendant j/s) arrives. Or post you it!

Wouldn't the one we used for the PG drives Omni Plus work?

Was hoping to replace joystick with your interface, power the rc rx and your interface from the bus cable, / joystick. As a plug in RC for multiple chairs.

[woodygb]

My previous internet searches suggest that it is a simple 5v voltage swing .

Agrees. Page 3...
5-Volt Dynamic
Joystick
A 5-Volt Dynamic Joystick is used to control the
wheelchair when in ‘Attendant’ Mode.

[woodygb]

I'd certainly require the joystick ...making the interface interchangeable with other 5v voltage swing chairs that you might own would require an external socket and a plug to replace the interface ....this plug would reconnect it back to original config.

[gcebiker]

Something must have changed with the App, or its my new phone.
Mine connects and will turn on/off via the phone but speed keeps zooming to 'halt' i can adjust the max speed but again it just resets nearly immediately to 'halt'.

[gcebiker]

Just read the instructions and i had mine set to BOX instead of Circle...i wonder if that was what was doing it ?
Oh and my refresh was at 50ms, i have changed it to 25ms now.

I hope it works now, ill try in the morning.

As I noted in another post - the Dyamic ACU has a 5V analog joystick, but it's dual channel in each axis. If the two outputs don't agree, it will signal a fault. Woody may have to double-up his digipots to make his RC adapter work for this.

[woodygb]

NOTE:- The APP seems to perform slightly different on different makes/models of Android phone/tablet....
I have a SAMSUNG Mini that will NOT connect at all.

I had to do that with an ALBER Wheelchair that used a JC2000 joystick with opposing outputs.
Easy enough ...I just piggy backed another digipot chip on top.

[Burgerman]

Dual outputs go in the same or opposite directions?

And no phone! RC by spectrum hobby stuff. Many channels!

[woodygb]

The JC2000 Joystick on the Alber is ( PN ) the PGDT uses ( PP ) .

XY axes The twin outputs of the XY axes can be independently selected to be
rising together in the same direction (PP) or opposed (PN).

I can trick... or if you like circumvent... the error checking requirement of the two X and two Y channels ( 4 signals in total ) by simply producing one reading but copying it to each of the (PP) channels of a PGDT joystick.

[Burgerman]

Whatever works! I am using a DSMX with programmable fail-safe at zero stick position for all these kind of things. So trick is fine! 2.5v either way?

I visualize a small plastic project box with the board from the attendant remote, joystick removed, and your RC interface, and a receiver ready to plug into any chair. All bus powered and able to turn the thing on or off or just left on with fail-safe rx holding zero permanently. So doing nothing unless I switch on TX to override the main control. It has a speed pot too. So that could be used, as can the overide button.

My carers are hopeless at driving my chairs. I use different ones and need to drive them next to my bed often! All are RC.

[woodygb]

Sounds doable..

[Burgerman]

Lets do it! Whats needed?

[woodygb]

A box of choice sized to contain all the joystick board bits and bobs PLUS enough room for a PP3 battery and your RC receiver?.

Plus some ACCURATE measurements of the original joysticks output voltages.

[LROBBINS]

To use the Dynamic ACU you will also need to include the User/Attendant toggle switch - it signals over CAN whether the ACU or the master remote is active. BTW, the ACU joystick, unlike the main one, can't be calibrated in software, but does need separate programming of some parameters. As you intend to throw it away and substitute with the RC mimic you might run into some trouble with that, but I don't know of any way to find out without actually trying.

No battery. Theres a 24v supply on the bus cable, and 5V for the joystick. RX needs 4 to 10V. Will be powered on all the time. So it can switch to the ACU as lenny mentions above. The RX fail safe will be set to OFF. When I turn TX on, it will move to ON.

I can do voltages very accurate! Do you mean while connected into the system or loose output unloaded by input impedance?

Or can we just have no dead-band and I can choose centre point with 2048 resolution by RC? Its super accurate/repeatable. More so than analog joysticks... So no need for built in fail-safe. The receivers I use have any fail-safe position I wish when no RC signal.

[gcebiker]

The older chairs use RS485.

I wish i was better at making my own board plans, that emulator i have in my Sig block works great.

As you have pointed out, its just the prototype plastic and zip ties, a better RC system of your choice would be more robust.

[woodygb]

I require enough space for MY board of approx that of a PP3 battery!

I can do voltages very accurate! Do you mean while connected into the system or loose output unloaded by input impedance?

Do both...

[Burgerman]

OK. What about having a clean linear output and letting the RC determine end points and centre points and dead band? Mines a computer and very programmable. Inc fail safe on all channels. Then no custom matched voltages needed?

[woodygb]

It will need to be programmed with a BEST GUESS at a preset fixed center OFF/Neutral voltage and MAX/MIN end points .

0v - 2.5v - 5v

But you will/should be able to play around with and move them within this range via your R/C transmitters presets.

[Burgerman]

Thatlwork!

[LROBBINS]

That is exactly what you will have to do for the ACU as its JS calibration can not be shifted by programming - you will have to "calibrate" your JS substitute to match what that particular ACU does (obviously, for the ACU itself to work without calibration it must have a deadband to take care of unit-to-unit differences in the center voltage).

[gcebiker]

I think its the app, changed back to the phone i used to use and its still doing the same thing.

When i press Speed + i see 'data 1' go up but less than a second after + has been pressed it reverts back to 'halt'

Moving the joystick produces no response in the chair while the 'data 1' is in 'halt' mode, if i am fast enough i can get the chair to respond but its less than a second and its back to HALT again.
