[opensource] A-10c EMI gauge with arduino and PCB KiCad file...

[overpro]

Some people might have the interesting to implement their own EMI gauges, I did one in last year, I'm glad to share the source code and the PCB design.

This is the demo thread: http://forums.eagle.ru/showthread.php?t=115997

First of the first, I'm just a web developer, and have very limited experience on MCU, PCB deisgn, so my work is not beautiful, don't argue me on that :joystick:

Thats pro for all that, really appreciate you sharing.

Thanks for sharing OverPro, awesome work as always.

A quick question - how do you work out the zero position of the gauge? I see some of the gauges offered support a zero sense.

A quick question - how do you work out the zero position of the gauge? I see some of the gauges offered support a zero sense.

 

this stepper motor is tailored for gauge and has an internal block to limit the pointer to [0,315] degree, so no need to sense the zero position, just do a full range move is okay

 

void GotoZero()                                {                                   
    for( int i = 0; i < 315 * 12; i++)                                    {                                        
       sendCmdTo595_1( B00000000 );                                        
       sendCmdTo595_2( B00000000 );                                        
       sendCmdTo595_3( B00000000 );                                 
                                      
       sendCmdTo595_1( B01010101 );                                        
       sendCmdTo595_2( B01010101 );                                        
       sendCmdTo595_3( B01010101 );                                 
                                      delayMicroseconds(180);
    }

This looks very good.

Infact this looks so good you almost made me reconsider my decision to go with screen rendered EMI set.

Thanks alot for your work

[Warhog]

I did a quick search on the net but I cannot find anyone selling the driver chip 6606. The company that makes them does not list any suppliers and I don't think they would sell half a dozen of those chips to a lowly little cockpit builder.

 

Do you have a contact that we can buy from ?

 

The stepper motors, however, can be found on eBay.

Thanks Overpro, just so I've got it right, you can basically tell the gauge move -315 degrees irrespective of current position, and it'll stop nicely against the hard stop without any damage?

[Duckling]

so my work is not beautiful, don't argue me on that :joystick:

 

Who am I to judge ? ;-) Looks great and you way ahead of me, thanks for posting OverPro.

[bnepethomas]

Hi Overpro

 

Did you get your PCB manufactured? If so can we order the PCB from the manufacturer, my thoughts are if the silkscreen etc have already been done, might as well not reinvent the wheel.

 

Cheers

 

Peter

[bnepethomas]

And another question, any specific Ethernet shield that has been better than others?

 

cheers

That's correct, I attached some pics of this motor, there is an internal block to make it hard stop. Because it's designed for gauges so the torque is small and will not make any damage.

 

And if you cut one or both of the blocks and polish it carefully the gauge pointer can go 360 degree full motion but in that case you might need to add some photoreflectors to detect the zero position.

Not really, I just made one PCB by myself, it's ugly :(,

but you might want to try my shared my PCB designs on first post, it's KiCAD files. You can use KiCAD to export the PCB to Gerber files and send them to a PCB manufactures to build some sample boards.

 

And another question, any specific Ethernet shield that has been better than others?

Peter

Oh ... I didn't noticed that there are more then one models available,

Just checked my shield and the chip model is WIZnet W5100.

[Deadman]

@ bnepethomas are you looking to build a replica engine cluster?

@overpro your work looks great

[Hansolo]

Very nice Overpro. Thanks for sharing.

 

A few small noob questions. It looks like a Wiznet W5100 ethernet shield you are using on a Arduino Mega. Do you know if it works with the Uno as well.

 

Again thanks for sharing

 

Cheers

[bnepethomas]

@ bnepethomas are you looking to build a replica engine cluster?

Hi Deadman - not quite the cluster, I've got the Simmeters stack which I'm happy with, but do need a couple of others like AOA, and I also noticed on the stepper motor site, one of the motors has a zero position sensor for vehicle clocks. Ever since building the F16 I've wanted a clock with hands that follows the sim time, so this could be the perfect storm.

 

Also have some quasi-evil thoughts about doing an F18 pit when that is released by DCS.

 

Having something that is open-source project helps protect me against another manufacturer going wheels-up.

And thanks for this, I like the UDP idea over serial, it frames the data and offers higher throughput, time to take the leap.

 

On the PCB design, thanks for sharing that, I've installed the Kicad S/W (that pretty cool), just learning how to drive, next will be learning how to solder SMD components, which will be a mess :).

Hi Overpro

 

I think there may be an additional file needed in the project. When I click on the .cmp file to open it in cvpcb, it is nable to find cdu.mod. Looking at the project preferences, I think its still hiding on your d:\projects\kicad\library\cdu ;)

 

cheers

Sorry I didn't check the files carefully, now I have fixed the Kicad CvPCB symbol to footprint associations.

Please pull the files from github again, and make sure you add the default symbol footprint libraries by using this method:

 

1. copy this file

d:\kicad-winbuilder-3.4\kicad\share\template\fp-lib-table.for-github

to this place, ( remove ".for-github" from the file name )

%userprofile%\appdata\roaming\kicad\fp-lib-table

 

2. restart KiCad, and open Schema file and open CvPCB, this may take a few seconds because CvPCB will go to github to download the footprint libraries.

And you should good to go.

 

 

Please let me know if it works or not.

 

ps: I also uploaded the gerber files to github, just in case anyone who wants to have a try ASAP.

Hi overpro, Thank you for your share.

 

I don't understand how to connect ( CONN2 2 pin ) ( CONN3 3 pin ) to arduino pin?

and how to connect ( CONN4 4 pin ) to stepper motor pin ?

 

Can you clearly tell us the installation step?

 

 

Otherwise, i can not find the file as below

d:\kicad-winbuilder-3.4\kicad\share\template\fp-lib-table.for-github

Hi Marick,

 

Below is the screen shot of the PCB view, connect your 5v power source to CONN 2 pin and be aware of the +(VCC) -(GND).

For the CONN 3, connect CONN3-SER, SRCLK, RCLK to Arduino 22,23,24 or 25,26,27 or 28,29,30. Because one board controls 4 stepper motor, so 3 of this board can control 12 stepper motor which covers EMI panel. You can also attach just one board with one stepper motor to test your build.

 

The CONN4 should be connect to stepper motor, if you are using the VID29xx or similar motor, the connection should be like this:

 

I will post some pictures later to indicate the relationships between the 4 conn4 pins and the EMI gauges.

 

Regarding the fp-lib-table.for-github, because I'm using the latest nightly build of KiCad, the project management is quite different compared to the downloaded Windows build which was released in 2013 July, I recommend you compile the KiCad by using KiCad-Winbuilder: https://launchpad.net/kicad-winbuilder
