  • I received an email from someone on the opposite side of the planet asking me for help. They had a tractor with a dead digital dashboard, can I help them fix it?
    This ended up being a bit of a journey down a rabbit hole!
    I'm not an expert, but I do enjoy trying to fix things.

    The fact that you'd be willing to take apart something you own that works perfectly fine, just to help some random guy on the other side of the planet says a lot about you. The world could use more people like you good sir.

      Thanks👍. He seemed to be in a bit of a pickle and it wasn't such a big job and he sent me a programmer. He also offered to pay me, but I said it was fine. I also volunteer at our local repair cafe, which we help people in the community repair their broken items free of charge (unless parts are needed and then it's up to them to pay for the parts).

      I'll let you in on a dirty little secret: People who fix stuff usually get a little bit excited when something breaks, or when somebody comes to them with a problem like this, and they're only too happy to have an excuse to take something apart to figure out how it works. At least that's how it is with me anyway.
      Helping somebody is just a bonus.. A little cherry on top! 🤣

      @@JoeBob79569 Helping somebody is just a bonus, sadly though so many people consider the efforts worthless. As a result I stopped helping out, it was never for the money (I never got paid!), but I can't abide how ungrateful people can be. On saying that I do recall how grateful a local farmer was when I repaired his electric fences - I was able to do it for a few quid (popped mosfets usually) saved him hundreds and a lot of time too!

Most of the time I end up getting some compensation anyway but helping people and sating my curiosity is always the best part.

    The conversion is simply Binary Coded Decimal (BCD) to decimal! (not some secret code to hide the true value). If you said this, I missed it. The addition of 6 when the value of a 4 bit nibble gets to 9 forces the number into the next nibble. It brought back memories from college in the late 80's playing with 8085 microprocessors and 74 series chips to drive 7 segment displays from BCD outputs from a microprocessor. PS recently found your channel and think it is brilliant! I find the real-world PCB rework very good to learn from as it shows ongoing real issues that will improve my skill now I am retired and picking up a new hobby.

    • @BuyitFixit

    Save yourself the time and trouble (and risk) to remove a chip from the board, use some DIP test clips. Most of the time you can read/write EEPROMs in-circuit. Test clips are available for SOIC as well.

    • @BuyitFixit
      @BuyitFixit  Před 7 měsíci +1

      Thanks for that. I've got some SOIC test clips, but I've had limited success when trying to read eeproms in circuit. I tried with a landrover ECU a while back and it wouldn't read. Was just easier to remove the chip.

    • @BuyitFixit

      This one is pretty basic, I think it's only the dashboard that's computerised. I dont think the engine has any electronic controls. The newer ones are way more complicated and pretty much all controlled by computers including the engine like a modern day car.

      A welder helps if you manage to let the block freeze. I live in Austria, home of the legendary Steyr 80 series tractors, one-cylinder Diesel pigs from the 50s. Most of them have had the block welded at least once, some twice. Some of the T80s were sold without any electrics whatsoever, the posh ones got two headlights, either a combined rear/brake/number plate light or two rear/brake lights and a number plate light, a glow plug, a generator with regulator and a starter. Oh and of course a horn.

    Most likely used the same software to dump and write as it has an hex editor, my guess is he searched for your hours, came back with a hex code, he then converted his hours into hex code and replaced and reflashed :) how I repair corrupt mac bios and use a dump I have and change the serial back to theirs :)

    Re. the "magic value", it looks to me like it's using a variation of BCD (Binary Coded Decimal). If the value was stored in binary, they'd have to do the conversion from binary to decimal to display it, and that might be too much like hard work for a low-cost microcontroller. Using some form of BCD would be easier. With the digit 9 represented by F, adding 1 would make it wrap around to 0 and generate a carry into the next digit. It's easier to detect digit 0 and then add 6 than detect digit A.

    • @BuyitFixit

      Could well be. Someone else mentioned similar and it seems a common way to convert to BCD by adding 6 👍

    Its pretty interesting that they decided to store the decimal value with hexadecimal digits. I would have expected to see a hex to dec decode at some point. But you're taking the hex value directly and treat it as a fix-point-decimal and it seems to work.

    • @BuyitFixit

      It's stored as BCD binary coded decimal. It seems the add 6 is a common way of converting the value (a few people commented after making this video) 👍

    how you ever learned about HEX code is beyond me. That is something that almost everyone has no idea about. When I was taking programing in College, we had to write programs in the different types of bite level codes so we could understand how they work. Not an easy class to take either. Now, if you were teaching that class at the time, it would have made more sense to me, and I would have caught on faster. Awesome video! I am sure years from now there will be someone that finds this video and will learn how to program the proper way.

      When I was a kid and got my first computer (ZX Spectrum) I remember messing around with hex then, and even on the commodore 64). I still remember Jet Set Willy when it first came out and everyone wanted a copy of it, but it had some pesky piece of paper with all of these codes you had to enter before it allowed you to play the game. I started searching through all the program and found all the 195 bytes which were the jump instruction that caused the cpu to jump to that location. I then tried calling the locations one by one to see what they did. Turned out location 34499 was the part to enter the code, so I did POKE 34499,201 (201 was the code for return) so when the game started it now jumped to the key code part and immediately returned without displaying it or asking for it to be entered and started the game. I think I was around 15 at the time 😂

      lol, right out of the gate you were a genius! My first computer was a TRS-80 from Radio Shack. If you wanted to play a game you had to know basic dos to program it, then you could save your game to a cassette. After I learned basic dos they came out with the extended vision of the trs-80. I never really messed with the hex or binary code though. Once I got into College I learned how to program in C, and from there just about all the other languages, but I really didn't like it too much, so I changed to Computer Forensics and learned how to hack, or should I say ethical hacking. lol I think that's awesome you would still remember how do work with HEX code. Not a lot of people understand it, but you would make an awesome instructor on it though.

    Very impressive, well done! :) Certainly made interesting video too.
    Brought back a memory of my dad's old 1995 VW Golf Mk3 Variant, at some point the instrument cluster digital LCD odometer panel started showing only parts of the reading, except when the temperature was colder than -20C, then the numbers showed up completely.
    At the time I didn't know much about electronics, but now I'm guessing probably the LCD display solder joints were cracked or something. Eventually the whole instrument cluster was replaced.
    Too bad CZcams didn't exist back then, would've saved a lot of money if I knew back then, what I've learned now from yours and others repair videos :)

    For odometers in cars where storing in EEPROM would happen more often than the maximum numbers of write they use a simple wear leveling methode which only works for ascending numbers: There is a row of numbers stored, say 4 times. The highest one is the one being displayed and the lowest number is the one to be overwritten next. So that is a 1:4 wear leveling. Works perfect, because I did this with a PIC16F874 back in 2001. The products (about 2000 were sold until 2016) still come in for service and no EEPROM has ever failed until now.

      @ChipGuy Před 7 měsíci

      @@BuyitFixit Yeah that is odd. With the checksum being explicitly for the counter only, one would guess that the 93 must be related to that counter value somehow. But I have no idea what it could be. Concerning wear leveling: After coming up myself in 2001 with it, I found the same methode in the cluster of my VW Golf in 2016-ish. The blue LEDs were so dim that I had to replace them. VW also used another methode for storing the 0.1km odometer values which I didn't bother figuring out.

      @@BuyitFixit One idea about the two counters: Storing it twice could be a way to determine if the value was changed at some point. While one of them is displayed and can be changed with the programmer, the other one can only be read. This could be used as a tamper detection.
