Been busy with other things.

Got the CPU into the library

Will try Kicad for this, now its Mentors Design Capture.

Fred, Below is my personal view, others may have other views: I agree that you can achive a lot by clever coding and full utilization of the resources, and I have also done so for z80 z80180, 68332 etc But doing a design in 2015 it makes more sense to use more recent products. Being able to spend le...

I Probably will use the SPC5674FF3MVY3 http://se.mouser.com/ProductDetail/Freescale-Semiconductor/SPC5674FF3MVY3/?qs=sGAEpiMZZMto2ohCYbAIUb%2fM%252bd5ceTLYKweMJQCCJ5M%3d http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MPC5674F So..... free ems software will still be usable to me but m...

installed git and downloaded the vanilla. tools downloaded since before looks as if i managed to compile HOTEL I dont know anything about the versions, so i will need to read up on this forum on how to proceed. I have understood there is also a simulator somewhere to generate physical stimuli. will ...

How did this end ? was this code made part of the "release" or still under development ? This specific functionallity of an ECU, knowing the flywheel position, acceleration , deceleration of the same. Being able to handle the jerkiness during crank and even due to high compression engines ...

todays work: read datasheets on the cpu XD / XE version, XE seems more sexy, faster and of later date, looks as if the errata list is shorter also. in general the processor is a bit of a dissapointment, page swapping for most things, me not like. installed virtualbox on a laptop, guestadditions. ins...

Ordered the #108 just for fun from here

Starting to draw schematic symbols for the CPU

Guess it takes 2-3 month before PCB manufacture.

4 layer PCB is asumed for now.

I plan on making a diesel ECU for piezo elements (or both types) 4D56T (mistsubishi) Also plan ECU for petrol engines. Not only that, but with home-made HW I did my own ECU for wankel, long long time ago, so I have some practice. I do HW/SW on daily basis as its my work. Biggest problem is time (as ...
