HE351 code for me78569

[me78569]

Found the issue.


It seems that the canbus shield uses pin 8 for an led.  If I bend the pin 8 on the canbus shield so it can't make connection with the arduino then I started to get rpm readings.  It looks like I am getting some interferience though . I seeing rpm readings steady at 1260, then jump some and settle back down at 200 something. 

Do i need to twist that pair of wires?

[hakcenter]

Never twisted mine. You have the 10k cap 10k on the vr lines ?

[me78569]

No cap yet

[me78569]

WEll I am pretty sure I burned up the canbus shield.  After I installed the 9924 and did the pullup to pin 8 ( now I find out there is an led on pin 8 of the canbus).

This is the second can shield I have burned up since starting this project, both of them sparkfun shields.  I ordered a seeed can shield and have edited my code and your 1.1 code for the new can library they use. 

More fun to come I guess,.

not having much luck it would seem!?

On the other hand, you're getting 'experience' (it's what you get just after you need it)

[me78569]

Seems like one thing after another haha.

Oh well work through it.

[hakcenter]

Should just get my board... lol

if you know where the issue is thou, the mcp chips aren't that expensive to replace

[me78569]

The seeed canshield was $11 shipped. 

I will be getting on of your boards after I pay for the wedding and now the additional $2900 for the surgery my future wife needs on the 16th. 


Ugh.

[Rx7man]

Just push the wedding and surgery back a couple months, she'll understand

[hakcenter]

Surgery oh noes

[me78569]

haha yea I can see that convo now,


" hey hun, gonna have to push back removing your cysts and polyps from your baby making oven.  Daddy needs some more parts"

hahahah, any you guys got a spare room for me?  dog house wouldn't cut it.

[hakcenter]

i got a cabana in the back, free rent no problem

So rather than using the setup section to define what curve is selected I have done this.

Code Select Expand

////////////////////////////////Watches for the pot position when pot switch is off to see what turbo curve is selected//////////////////////////////////////////
   void Watchpotcrv() {
      if (!eb_mode && !pot_mode) {       
        if (PotentiometerValue > 970) {BoostMapMode = 'E';}
        if (PotentiometerValue > 20 && PotentiometerValue < 970){ BoostMapMode = 'D';}
        if (PotentiometerValue < 20){BoostMapMode = 'P';}
         
        if (LastBoostMapMode != BoostMapMode){
          if (BoostMapMode = 'E') {memcpy(turbo_curve,turbo_curve_1,sizeof(turbo_curve));}
          if (BoostMapMode = 'D') {memcpy(turbo_curve,turbo_curve_2,sizeof(turbo_curve));}
          if (BoostMapMode = 'P') {memcpy(turbo_curve,turbo_curve_3,sizeof(turbo_curve));}
          LastBoostMapMode = BoostMapMode;
        }
       }
      }

I know the memcpy function is slow, but I am assuming that by watching for a change in the inactive pot position and skipping the memcpy if the lastboostmapmode is the same as boostmapmode it should work right? 

I have it set in the timer section to only run this once every 900 millis or something like that. 

thoughts? 

Also in your lbb code I have a question about  "staging_enabled"   I can't find anywhere where you set it to true?  am I missing something? 

[hakcenter]

There is staging code in the calculate vane position, to skip the WOT top end section and just use ms timing / staging.

For people that may just have a drag only car and want a specific turbo response versus time.

[me78569]

so you just manually set staging_enabled to true in the lbb common if you want that feature?
