Re: Puma board for FreeEMS
Interesting, I know in the "comms type wars" there were a lot of ETH advocates! :-) I know I'm converted .. but don't expect much from those things which blindly convert 232 to enet. Once I designed something with enet from the ground up, I was much happier (so far). Great throughput and ...

Re: MAX9924 configuration and use cases
... the zero crossing on the falling slope of the waveform corresponds to the moment when the sensor and gear tooth are exactly aligned. ... checkout my mini whiteboard: http://i53.tinypic.com/ei8i8y.jpg like jean says, as the tooth approaches the pickup, you get a rise (assuming correct polarity) ...

Re: MAX9924 configuration and use cases
A sensor of matched b/w should look more like this:

except it looks like he's got the pickup input backwards.

Re: MAX9924 configuration and use cases
Can anyone with a VR and 20k resistor confirm the RMS voltage? It's not as easy as this .. not all VR pickups are the same. The characteristics of the pickup are matched to the expected bandwidth. The pickup for a single tooth @ 10krpm is going to be drastically different from a pickup that can han...

fine with me.Fred wrote:What I'm going to suggest amounts to the same thing, though. I suggest that if a device is sending non-packed data, it must specify where the gaps are. IE, what is specced in the xml file must match what is sent.

Re: Data Source File Format And Structure
we need to specify bit ordering in bitfields .. using the name:width struct trick is non portable... your code needs to generate correctly irrespective of platform, right? some kind of tag which says 'lsb first' or 'msb first' is all thats needed I think. compilers usually have little_endian or big_...

Re: Bench Testing Code (outputs, math and injectors)
I have seen people monitor the current to the injector (which I kinda like - you can actually SEE the pintle stop moving). Dynamic flow is no way related to this trick (or the knock sensor zip-tie trick). I spent some time on my own injector flowbench to prove it to a co-worker. Check this link for...

Re: Data Source File Format And Structure
I started looking at the mm .. It's very dense and I'm walking through it very slow. I don't really understand instances. They aren't as descriptive as something like notes/errorids/payloadids/structures .. 1) could you please explain a little more what instances are describing ? are they just confi...

Re: What is the Consensus on Winlog?
Maybe I was harsh .. it does what it needs to do and I don't really feel bad about paying the 20$ to unlock all the features. I wanted to extend it through his plugin interface and thats where I ran into problems. If you plan on doing the same, beware. I ended up moving on to TunerPro .. now that gu...
