Fuckin-a, Bubba!
:bigtu: So, the 9926 circuit just didn't cut it for you, then? Man, I'd really love to get in there with an actual oscilloscope on one and figure out what was going wrong. So far, I've just been deliriously happy with that chip. |
I dont know exactly what is the issue with the 9926. I haven't given up on it yet but I dont have an o-scope.
But for now it works so.... |

Maybe the Y8s should send his little 9926 board over to the Ben?
|
that shit's installed. I'd rather just make another one.
|
oh you left it on the mainboard?
|
yeah it's still there for future expansion. wired only to power. how un-green of me.

We should have one of Jean's 9926 boards around here. We've also got a new sequencer to test out. The hardest part will probably be the fabrication of a live sensor test rig. |
I used kday's 9926 reference circuit. super low component count.
|
Matt, did you connect the VSS to the MS3? If so, what settings did you use?

Yes, I ran VSS in to the xpander CAM input without any extra circuitry. I first tried PT4 but there was no pullup. It'd probably work on any of the inputs with a pullup.

Matt,
Did you get the max9926 based input circuit working on the car? -Raj |
he never did, he went with Abe's circuit.
Honestly, you dont even have to build that... should work on regular Opto input and the MS3x cam in. |
Nope, never did get the 9926 input working.
If anyone wants the circuit to try, I can mail it to you for a buck or two to cover postage. |

I recommend using the VR input with a pullup. Works fine and is easy.

Hell yeah. I would love to play around with it. What is your paypal id?
Thanks. -Raj is that you? |
Well, background is chemical engineering/Physical chemistry and I have done a lot of instrument computer interfacing. I can give it a shot and see if I can figure it out.
