6-Wheel Drive Discovery II - Am I totally mad ?

More than likely something else has absorbed his energy, could be a family thing, maybe he is unwell...

I doubt very much it's a thin skin thing.
 
I'm thinking it was quite a big job...body off replace cables etc...re book test etc and probably a bit costly as well as taking time to get it up to his best and tidy standard..
 
Just found this thread and it's an amazing piece of work! I'm an electronics engineer, and have made a custom LCD binnacle display for an Elise S2 using ARM, and some other bits, but you're taking this to another level with the amount of custom work here. The combination of mechanical engineering, electronics design, firmware programming and FPGA HDL development is a joy to see working together, and the progress you've made with the build is mighty impressive! One question, I assume you use a DMZ or some other filtering on the car's internal network so that mobile devices etc don't interfere with the data flowing between the various modules?

I typed this into Google translate and it just said "Automatically detected English, translate to English" and I'm still none the wiser.

Jeez, @dieseldog69 you've just let down probably most of the forum members here.... For your info, FPGA is the Fuel Pressure Gate Attentuator; this works in a very harmonious way with the HDL, the High Dash Light and the resident flux capacitor. Now you know.. :)

Doc?
 
That thing you describe is something totally alien to pre-1998 Defenders in particular; that said, I'm actually using one of them there beasts disguised as a Raspberry Pi to monitor temps et al. Watch this space!
 
@dave658 Hi, any update on the project? Tnx
I'm a little blocked at the present by another project. I have a spare D2 chassis waiting to accept the bodyshell while I do the mods, and I've figured out the safest way to transfer the bodyshell is with a crane, but the crane needs to go exactly where my other project vehicle is currently sitting, so I have needed to get that complete before I can lift off the body on this one. I have all the cables measured out and all the parts I need to do a really complete and through job, just need the access :)

Well thank you !

I'm also an electronic engineer, the mechanical stuff is just what I've picked up along the way, and benefitted from some outstanding advice from others to get to where I need to go.

Most of the modules are ARM cortex processors with a bunch of custom I/O surrounding them. I wasn't aware I had mentioned FPGA usage anywhere, but the move from EMU III to EMU IV saw the regular arm processor replaced with a Xilinx Zynq 7010 which is essentially a medium density FPGA surrounding a dual core ARM.

VHDL is what I spend my working day doing to be honest, so it wasn't too much of a stretch. The FPGA section calculates rotational speed, rate of change and angle of all 4 camshafts and the crankshaft accurate to 100th of a degree, and presents them in registers for the processor cores to apply the lookup tables to. They in turn program into the FPGA, starting angles, dwell etc for all the injectors and spark plugs and the FPGA takes care of the micro-precise timing.

I don't think anyone else is taking this approach, Bosch certainly aren't and none of the 3rd party units I have seen do either, but front-loading all the blood sweat and tears makes a lot of the tasks associate with running the engine a lot easier.

I'm not sure why you think I need DMZ in the vehicle networks, the networks in question are CAN based, not IP based so the idea of a DMZ is rather unnecessary - did you have a particular issue you think I should be addressing ?

Man, I think you guys lost me somewhere around the second paragraph...
Read it all through to the end and went like "wait, what did I just read?"

Reading it a second time didn't make any difference either ....like trying to read Cantonese using google translator

LOL, sorry, I would normally try to avoid quite such a jargon laden post, but I was answering very specific questions :)
