He351ve stand alone Arduino controller code for 2nd Gen Cummins

[Me78569]

Please post the error

I verified that I am using the newliquidcrsytal as you though,  attached is that library

NewliquidCrystal.zip

[Clarkwisely]

#include <liquidcrystal_I2c.h

 

 

[Me78569]

I can't see your images.  

 

Did you download the zip I posted and add it to your library in arduino?

[Clarkwisely]

IT WORKED 

[Me78569]

Great news!  That's the hardest part. 

 

 

[Clarkwisely]

ya thanks gonna start wiring it now thanks a bunch.

 

 

[Clarkwisely]

Ok so I got it all wired up and got put in the truck don't have the sensors hooked up yet but when I turn the key on the display is blank it lights up but just abunch of squares is this normal, just wondering if I have it wired right putting the turbo in tomaro and it's my daily driver so I hope it works out.

 

 

[Me78569]

I am guessing the address for the screen is not correct.  If you look on arduino page 1 line 24 you see "0x27"  

 

Also does your screen have a i2c board on it? 

 

Google how to find the address of a ic2 screen.  Once you find the address change the 0x27 to whatever you have.  

Also verify you have the sdasca wires in the correct position for the screen.

Thanks Ill try that thanks abunch

[Clarkwisely]

Well got the turbo all installed still can't get the display to work and couldn't get the turbo to change the address for my display is the same 0x27

[Me78569]

Make sure the sda and sca wires for the screen are in the right position.  How do you have the screen wired?  Have you tried reducing the brightness/contrast of the screen using the adjuster on the i2c board?( Guessing that might be it)

 

How are you trying to make the turbo change?  Does it cycle when you apply power to the turbo?  Any noises from the turbo when power is applied?

[Clarkwisely]

You can see it move the vanes out about a quarter inch then goes back  exhaust brake won't work and the manual pot switch won't change it

Sda wires and sca are in the correct ports like 4 and 5 I think

 

[Me78569]

Adjust the screen contrast using the small blue pot on the i2c board.  Sounds like the contrast might be all the way up.

 

Please post the exact canbus board you got.  Some boards use port 9 some use port 10.   You might have to change the channel in the code.

 

 

[Clarkwisely]

I adjusted the contrast and now the screen looks ok but I can't get the turbo to do any thing  no exhaust brake or any thing at all

 

[Me78569]

I think the canbus used pin 9 on that shield.  My code is setup for pin 10.  I think the first or second tab The code has something like "McP (10);". Change that to 9.  Recompile and upload.

Page 1 line 23 change mcp can1(10) to mcp can1(9)

[Clarkwisely]

I'll try that in a bit

 

[Clarkwisely]

that didnt fix it either also the exhaust brake switch goes to pin 9 so it will have to be moved cant get it to do anything at all

 

[Me78569]

Try swapping the canbus wires from high to low.

 

 

[Clarkwisely]

That's the next thing I was gonna try

 

[Clarkwisely]

I haven't got to try to swap the can bus wires yet hopefully tonight but  even if that was the problem wouldn't the display still show something other than just a blank screen
