Fred's firmware development diary

[Fred]

You can now alter the fuel pump priming period. Default is 4 seconds as always, however a bit shorter or perhaps longer may suit your needs better.

[Fred]

Rough list of things that I need to do in the short term:

Essential improvements in robustness:

• http://issues.freeems.org/view.php?id=120

Improves performance of controller:

• http://issues.freeems.org/view.php?id=124
• http://issues.freeems.org/view.php?id=272 related to 118 below
• http://issues.freeems.org/view.php?id=273

Improves reliability of controller:

• http://issues.freeems.org/view.php?id=118 related to 272 above

Possible bugs:

• http://issues.freeems.org/view.php?id=500
• http://issues.freeems.org/view.php?id=753

Good to have, but not essential:

• http://issues.freeems.org/view.php?id=69
• http://issues.freeems.org/view.php?id=139

120 is the priority, then 272/118, then 124, then 273, with random other things, and work on the soon-to-not-be-a-secret app mixed in.

Other than those, there are these two lists, too, just for the record:

Only a week and a bit until I fly to visit engine number 19, and I'd like to take the secret app with me to use.

I'd like to have those 5 issues nailed before July. So I have two months to achieve that.

I have a lot of other things to achieve, too, though. Like not ending up back on the street :-p

Before I get stuck into 120 I will try to get three configs included/updated.

with random other things, and work on the soon-to-not-be-a-secret app mixed in.

Just spent a few minutes (< 30) and added a new decoder for a new engine that I might get to play with on my trip in a week's time. Added a bench test mode for it too. I love the independent decoder setup. So easy and clean! :-)

Screen shots by 8th July, I promise :-p

I just did a quick write up on how to release software, if you're interested, have a read here: viewtopic.php?f=45&t=2114

[Fred]

Good stuff happening, nothing worth describing, more soon! :-)

[Fred]

This is the J Series decoder that Peter and I did, being used on a four cylinder cranking cleanly:



Could this be engine number 20? Only time will tell. More news on that soon.

Today I:

Chatted to Mike about reset detection:

http://stuff.fredcooke.com/reset.and.co ... .mike.html

Hacked up some firmware to fake resets and comms drops for him:

(15:28:17) Fred: http://tmp.fredcooke.com/FreeEMS-0.2.0- ... -4and1.s19 < fake comms drop outs
(15:28:17) Fred: http://tmp.fredcooke.com/FreeEMS-0.2.0- ... -6and1.s19 < fake resets
(15:28:17) Fred: Both every 30 seconds, do not use these on a car... Andy... :-) Instead everyone should use them for testing Mike's new code once he pushes it.

Abused someone for trying to promote FreeEMS before it's ready for the masses.

Spent 1:40 on skype to the same bastard telling stories and talking shit.

Posted up 31 posts of pictures of the new secret app in a new secret development diary thread for it (to be released soonish).

Talked circuit boards with various people.

Visited the local yearly market with the mrs.

Gave Sean a bit of mild code review.

Received a bit of mild code review.

Watched this interesting video about Africans stealing entire ships: http://www.youtube.com/watch?v=UxqyZsCQv4Y

Received some excellent news about a package arriving in a strange land.

Received some bad news that an hour of good data was lost due to this bug: http://issues.freeems.org/view.php?id=838

Received some excellent news about a engine 20 in the making (see above).

Gave some advice on how to configure timing without a timing light.

Decided Andy needed a big pat on the back: viewtopic.php?f=41&p=33911#p33911

Cooked dinner, ate dinner, drank some wine, had a few laughs with the lads around the world.

Tried to do something nice for someone who has been shat on by an arsehole (pun not intended). And got told to sod off. Too bad for him. Only fools and horses.

Various other things, none of the above being in anything like the real order.

Just another typically busy day running this project.

Bed time!

Fred.

6am, can't sleep, reading about statistics. What fun! :-p

[Fred]

Following on from the sync confirmations stuff, here's another useful case for it. Wrong decoder for the engine setup. Sync is possible at first (potential kick back etc) but upon continuing cranking the "ok to schedule" bit is never set again, because sync is never confirmed consistently enough. Perfect.

[Fred]

This is important, people. If you're reading this and possess a TA card or any other working hardware, throw some fresh firmware at it from the build server and give us a hand getting EMStudio ship shape.
