v2.0 / Re: Android development

I wanted to just give an update to whoever reads this thread anyways.

I've been slaving over the application, and updating the lbb code, to really go hand in hand the last week. It's been absolutely apparent that bluetooth communication has it's serious limitations, and making programmatic timeouts are just not feasible.

I can get round trips of code ranging from 40ms all the way to 140ms, with the devices right next to each other. That's when I know how many bytes to expect, so best case 0 latency wait. It would also be a terrible idea to make the application wait up to 150ms between sends and receives, it would just be so slow and laggy and pointless. But now a timeout of 2-3s actually works and shuts down the connections properly, etc etc etc. All around just 100% better than using buffers and either getting old data, or waiting for new data, then jamming up and breaking.

What that means realistically is that a code upgrade is going to be absolutely mandatory. So I'll basically just force over the bulk data anyways, and it's insanely fast. Absolutely no reason to not use it.

Graphing is in, it's looking pretty good so far. Once I get the app and LBB code stable I'll push out the updates and really hone in on graphing, then log saving / possibly review.. however I think csv viewing via google sheets, is probably the most ideal. Maybe automatic data graphing can be built into sheet creation /shrug

Anyways thanks for all your patience.

v1.0 - v1.1 / Re: LBB Common Code
« Last post by hakcenter on November 02, 2018, 11:04:17 PM »
v1.3.2 update

Minor Changes:
  • Updated Serial code & adjusted serial commands curve_rpmX= & turbo_curveX=
    • Just more specifics on making sure the command is read properly.

at one time I had a sketch that displayed any information the turbo relayed back to the lilbb.. if you're getting info back that would tell you comms are working.. I'll see if I can dig something up tonight.

4.8v dc on C7 and 0.68v dc on C6 ..... Crystal ?   I measured  on the pin facing each other (inside pin) to GND.

Ok I'll ditch the fluke and keep using my other meter it's just your regular amp clamp with a auto ranging meter built in. I also tried my 9.99 Canadian tire meter .it also had similar readings as my amp clamp.  Except it reads open when  I test my can bus lines to GND.  (I'm assuming it can read over 20meg while my amp clamp does). 

I did get a new crystal and caps but didn't change them.. caps measured fine last time I tested them.   Did you test with just USB power?

As for the turbo , it was bought from a friend that upgraded to non vgt. I was told it worked fine and was tested before it was removed. But I have not seen it work in person.

Ya sorry I don't own a Fluke :(, just a basic meter who know's just how accurate it is.

Maybe the crystal got damaged as well ? I measure 1.8vdc and 1.5vdc on the inside of the caps leading to the crystal. Don't really know a decent way to test the crystal but it needs to be 16mhz.

What's the story on the turbo itself ? Working from a friend ? eBay ? Craigslist ?

yeah I unplugged  shield from arduino . I tried measuring with a different non RMS meter just to see . Not sure what meter your using , but there is a difference ... i'm little confused  now. with a regular meter i'm getting 15meg bettween r6 (com lead)  and either side of R3 (Red lead).
Testing Gnd(com lead) to to the can lines with Regular meter i get 30meg

With the fluke RMS, doing same test R6 to R3,  i get 18k and 6.4k  On R3 . (big difference)
I 'm also getting 8meg Gnd (com) to either can bus lines   

Also reversing leads gives me totally diff. readings.
