Fred's firmware development diary

[Fred]

My top secret project is underway!

viewtopic.php?f=25&t=1827

To quote Jeff Wayne's war of the worlds "slowly but surely they drew their plans against us".

PS, don't bother clicking the link. Only one user on this forum can access it. I'll move it somewhere more obvious once I make progress.

Pretty much absolutely every feature that the firmware has is now exposed in config! Today's additions: PWM, Pin/Port state/function, missing tooth tolerance.

63% progress on the roadmap: http://issues.freeems.org/roadmap_page.php?project_id=1

I'll tidy up some other things for a few days until three people verify the changes.

I've been working on generalising the even teeth decoder to handle crank sync and per cyl sync. It's not done yet, but that's because it's summer and the wife is on holiday and I've been doing other things. I thought it was time for an update here regardless of the fact that nothing has been achieved in the firmware since the last one. I'll likely complete that change and close that issue the first time that I put a full day into it.

Did some OLV work today :-)

Will try to finish that firmware commit later too. I wrote this thread while working on it: viewtopic.php?f=8&t=1843

Anti-trolling techniques are now official! viewtopic.php?f=17&t=1845

Commit complete, early 4age now theoretically supported OOTB! Think of it as hyper accurate distributor mode :-) Same exact code as Sim uses and Andy uses and Sean will use on his R1 powered buggy in 2017. That's enough for today. Time to do some maintenance on me instead.

For just one dollar per English speaking forum member you can sponsor a child to get FreeEMS installed on a girl's car.

A couple of cheap opportunities for EDIS/DIS/4cyl-wasted users to get in on the act here!

I'm so excited, I just can't hide it!

All logging should now be done with EMStudio!

At least, if you want me to read it, it should!

As a result of this, and new currently just-for-me hacks to OLV, I get the following output when I load a log:

Code: Select all

PacketsUnderLength:   0 Incremented when a packet is found that is too short
ChecksumMismatches:   0 Incremented when calculated checksum did not match the received one
PacketsParsedFully:   1725 Number of packets that matched all requirements and got into the log
PacketLengthWrong:    0 The length should match the ID passed in, if not, fail.
StrayBytesLost:       104 How many bytes were not in a packet! (should be low, ie, under one packet

Thank you for choosing FreeEMS!

Pretty sweet! All of this stuff needs to move to a console style window in OLV soonish as it's only available in the terminal you start it from, which many users just don't do.
