I made control board
And used Joystick Module
But it didn't work
Please give me the code I want it to work with the joystick model
CAN YOU GIVE ME sketch Modified code PLZ


You will find in this thread new versions of code that work better, if you post here you will have the most up to date information.
I have started working on it again, its summer here In Australia and I am getting ready for Squid season early in the new year.

I am now working on using the emulator to drive a Storm Arrow power chair with Brushless or 'GB' motors as Invacare calls them (Gearless Brushless)

The emulator works with the POWER MODULE , it replaces the JOYSTICK MODULE or in the case of woodys, used in parallel with a relay to switch between the joystick and the emulator.

To assist you better,
Please post pictures (as high res as possible) of the emulator you have built.
Please post screen captures of your data capture.

It is necessary when debugging this emulator, to supply a data capture of your board.
With out it there is no way to identify if its working.

Basic things to check are if the Shark Bus wires are plugged their corresponding Shark Bus HIGH, Shark Bus LOW.

Its not actually necessary to build up the emulator board to do the first phase of testing, the code can be loaded onto any Arduino Nano and snoop the output pin.

The emulator also relies on Libraries written by other people, changes to those can sometimes throw a spanner in the works.

If you start with supplying pictures of your build and data capture, we will be able to help you better. :ugeek:


As I am now actively working on this project again, I will post (On my webpage).
- Each version of the code that works, with out kinks.
- A video for each or links to past videos.

Issues with your build picture posted.

1. The biggest is that the code is written to receive RC inputs and you are using Analog Joystick inputs.
-- There for my code as it is, will not work.

Code will need to be rewritten.

2. Analog inputs into the Arduion are notorious for false reads, due to issues that are detailed in other Arduino forums.
-- This causes 'weird and unpredictable results' . Its the main reason i went from a build much like yours to the Nintendo Wii remote.
-- Joystick data reads via I2C are much more reliable.

3. We have no idea if you have a board wiring issue.

would it be possible to set up a manual/RC selection switch? I have a friend that wants to be able to use the original joystick, and have a selector switch that switches to input from a remote control receiver.

Yes.

You will need to add in a double pole double throw relay or a manual switch .

Ok thanks! Is there a schematic anywhere of that arduino nano board?

Try this.... it is slightly different to gcebikers original nano layout.

That is a strange DPDT switch! Most DPDT's that I'm familiar with are NOT marked w/ the 0-I labels since that implies On / Off action, and a DPDT is really an On / ON switch, (in it's simplest type) since you have the ability to have live power in either position...

DT (Double-Throw) switches can be tricky to shop for as there are a lot of different functions in terms of whether or not there is a 'Center-Off' position, and whether they are momentary or toggle in either (or both) directions....

I'm sure you know Woody, but for others info, a DT switch can typically be either two position (i.e. On-ON) where it has to be on to one side or the other, or 3 position where there is a middle OFF position where neither side is connected, i.e. "On-Off-On"... If the action in one or both directions is momentary, they will usually put the momentary position in parentheses, i.e. the typical switch for an actuator is designated (ON)-OFF-(ON) - where it has a center off, and goes momentarily (when pushed) to either position to move the actuator in or out....

For the use in question, where you want to have either the joystick or a remote input, but (presumably) never NO input, you would want an ON-ON switch with no center off position.

Re: Dynamic Controls Power chair, RC Boat trailer project

Apologies in advance for my ignorance.
I've converted a couple chairs to RC/Ardurover control, but always directly with an s-bus motor controller. I have a new project on a Mk6i controlled chair that has a number of linear actuators that I'd like to use. They are strong and have positional feedback, which is great. But to use that I'll need to hijack the Dx protocol - I think.
I'm trying to determine if this project has been ported successfully to control an Invacare Mk6i DX protocol chair.
I've read through most of the thread and it seems that Shark and DX are not compatible, but I saw mentioned that the board developed here could be compatible with Dx with programming. Is that the case?

Many thanks!

I believe that the DX uses a completely different communication protocol.

Ive only done limited testing, mostly because the tow chair that is in the videos is working so well.

Connecting the Shark Emulator Remote thingie that i built up, the MK6i Power Module powers up (but then it wont drive, but that could also be because i tested it pre fixing the Joystick file settings with the HHP)..... so possibly similar code.

I have not yet sniffed the bus to determine what the protocol is, not since i was able to purchase a MK6i HHP and restore the chair to working condition after the file was named wrong in the PC software.
