Another guy did the hard work of the disassembly and stuff, once I had it I made a bunch of tunerpro defs and actually wrote a rudimentary datalogger that would poo poo out a signal that could be read with an OBD-II K-Line reader https://www.youtube.com/watch?v=VvwqEg-GXLs It never worked well, I eventually went Megasquirt after blowing a few headgaskets doing this on poorly hacked factory management https://www.youtube.com/watch?v=TlhIkL4xOR4

I dance (usually locking) and post on comedy forums. I also spend the majority of my time learning norwegian, swedish, korean and other languages i spend at least an hour or two working out and reading (not at the same time) and eventually want to take singing or violin lessons, and maybe learn how to do yoga properly if I don't have time for dinner or breakfast I just eat raw fruits and veggies i dont really have any "projects" except for academic projects but i do enjoy my hobbies Stay Safe fucked around with this message at 18:07 on Jul 23, 2013 |

Unless they have fixed them by now. PM me if you want something specific from there; i have most of it in my dropbox somewhere Also, are you talking about RPM calculations on the data tables? On LH2.4 at least, Bosch did it a really funny way, probably to save bits or something. Can't remember exactly how it works but feel free to hit me up.

jackdh4x0r posted:here is the wiki site we setup. I had to cancel my vhost so it is hosted by another guy thanks, that gives me some reading material for this evening. i meant how the code actually works out RPM from the flywheel pickup. timing is accurate to 0.75 degrees, but i can't work out how as the timing teeth are 6 degrees apart. i guess it's different on the jetronic because it only does fuel, whereas the motronic does ingition too. the timing code is all interrupt-driven and has multiple tooth counters going on, and can compensate for mis-counted timing teeth. its really hard to follow i figured out the table-reading code a while back. it's not how I would have written it, but it makes sense once you get your head round it. it reads like they were trying to save ROM space. the early motronics only had 8K so that makes sense, but mine has 32K and is 40% empty so they could have done it much more simply. i guess they just stuck with code they knew worked?

these are all really cool projects and just kind of make me wish for a little more technical know-how. for example my most advanced creation so far is a command prompt based RSS-reader for me to use at work so the wall of text makes it look like i'm doing something productive. it was fun and cool but it could have been so much better executed and i feel overwhelmed by the idea of putting more time into it.

HELLO I HAVE SPENT MORE THAN A DECADE PROGRAMMING AND I STILL FELL DEAD INSIDE, BUT THAT'S OK i often hear people saying the following things, and they're sort of anti-learning thoughts - i want to know the right way to do it, i don't want to waste my time - i often abandon my projects after playing with them and they stop being fun - if only i could do cool stuff like other people the reality is you learn how to program by making mistakes and then learning from them. so you need to go and make some goddam mistakes and terrible code if you wanna be a better programmer. don't worry about how many mistakes you make, just try and avoid making them over and over. it can take a while to learn from the experience. along the way you will have to learn new libraries, new platforms and languages, but that's ok. you'll be poo poo at them too for a while. BITE SIZE MORAL INCOMING >> if you didn't make any mistakes, you probably haven't learned anything from the experience. <<we have yet to find a shortcut to being better at something without just goddam practicing it all the time. so try these three weird old tippes. - write more code - read more code - edit more code the best way to do this is as a side effect, rather than a goal. you will end up doing these anyway. so if you are bored of your recent toy, make a new one. if you don't know what you want to code, pick one at random and spend an hour trying things. look at something else someone else has done and make a simpler, cut down version that's possible to implement in an afternoon. the easiest way to start doing this is aim low, and then aim lower still. i wrote a game once. my original objective was "draw a loving box on the screen", then i figured i'd change the code to handle keypresses, changing colours, moving, animating, and finished the game by taking a bunch of small steps first. if you get something working as quickly as possible, then you'll find yourself just sinking time into the project. OH poo poo HERE COMES ANOTHER MORAL you learn by copying others, and you'll learn quicker if you learn from other peoples mistakes. write some crappy project in an hour, maybe play on it for an afternoon, perhaps even the weekend, upload it to github, and post it here and ask peopel to tell you some unhelpful bullshit about how they'd write it. sometimes it can be useful. go and look at someone's github and poke around the code and ask yourself "OH JESUS CHRIST WHAT IS THIS I DON'T EVEN" check it out anyway and see if you can change something. tl;dr you won't make anything cool whining about how you're not doing it. you won't make anything cool until you do a bunch of uncool stuff first. go out and write terrible code, it's ok.

The effort is documented in his 1974 book Computer Lib / Dream Machines and the 1981 Literary Machines.

here is the thing i forgot to mention, i find it harder and harder to hack on side projects, all of my ideas are insane and too grand in scale to even begin with, and often boil down to "SCREW THIS LEGACY BULLSHIT I'M STARTING FROM SCRATCH". anyway despite this i have managed to have some side projects along the way but most of them i haven't touched in months. - buttbot so when #cobol first started everyone was writing bots so i dragged out some perl code I wrote when i was 16 and took flowenol's suggestion "write a bot that says butt", and then played around with it for a week before pushing it to google code. a bunch of people hacked on it, comics got drawn, basically it's the most significant piece of code i've written based on how many people it made giggle. - a million toy language projects i've written lots of parsers, some interpreters, some vms, and lots of bits and pieces to understand how platforms fit together. - hyperglyph/rpc poo poo i went mad at work and decided to explore representational state transfer as an ipc mechanism and it kinda worked, making p-lang rpc. i don't think it's incompatible with more contract based ipc though so i might revisit that at some point. - logo interpreter i wrote this during my day job as an excuse to learn javascript and also because i resented the day job. it was fun but logo is a terrible language underneath, and has that same sort of xfig like arcanery about it. it has a lot of weird idioms that seem a bit odd to modern eyes. right now really i want to write my own ipc system with it's own data description language, transport and application protocol, and then of course a distributed file system, and then my own browser for it, with my own little declarative interface language. because i've gone mad.

With LH Jetroinc, the ignition is an entirely separate computer... and the code is pretty much exactly what you are describing. scary, and interrupt driven. Lots of NOP slides, not sure if they are left over from debugging but they looked to be timing specific. Microcontroller programming for real time systems owns bones, respect++ for anyone who does it. When I was writing the ASM to output the variables for the datalogger above, I had to be very careful to make sure that poo poo didn't take too long... but at the same time I had to wait for the UART to be ready before sending another byte so I didn't clobber the previous one. And if poo poo took too long the car would run funny and sometimes the watchdog timer would reset the ECU. I never got it perfect because I blew the motor up.... three times. And Volvo redblocks are pretty stout motors; I definitely did some silly poo poo. It was fun, I wish I had the motivation to dick with that stuff like I used to. Car is sitting in the grass with some kind of fuel pump problem that I haven't troubleshot yet.  CamH posted:sup dude?

Deacon of Delicious posted:this is the part i can never figure out, the blank screen is my biggest enemy the best way to design something is to add constraints until the solution is obvious. sometimes the real problem is actually asking the right question, rather than finding the right answer. so let's start: i wanna make something - that can be working in an hour - in a language i know - that does something on screen - that maybe reacts to keyboard input so you write a boring program maybe in javascript that draws a butt to the canvas, and when you push a button poop comes out. now you have some code to edit, you can start to shape it. - maybe instead of a butt, it should be a catte, and when you press a key it purrs. - maybe i should be able to have multiple cats - maybe i should be able to get them to chase my mouse pointer then maybe you start something else.

tef, your advice is gold and i completely agree 100%. i pretty much do all those things in game dev projects. i'm not a designer so much of my projects are: 1. play a new indie game with an interesting mechanic. 2. try to write a clone of that game. 3. get enough done to feel like i've implemented it correctly and is playable and then shelf it. i'm working on sharpening my design chops since i feel i can code up almost anything given enough time, i just don't know how to make a game fun. when i was brand new to game dev with XNA, i pretty much did your steps. 1. get a thing on screen. 2. move a thing with keypresses. 3. make it collide with other things via checking intersecting boxes. 4. add <interesting thing i've not tried to implement before> my buddy gets stuck in a rut because he never tries to code, he just wants to read about how to be a good coder. the absolute best way to learn is to code code code and then yell at yourself a month later when you realize it's all poo poo and then do it better. game development is pretty much the only thing keeping me in software development and sane because enterprise java web development is nothing but solved problems and spring/hibernate stacks and boring BI poo poo.
