    That looks like a great resource!

    The RX & TX that are pinned out are from SCI3-2 …. the same one used to program the chip over the serial port. So they may be there more for initial programming instead of actual use. Unfortunately, this is a write-only port … if you send some zero characters to start the communications, the first thing it does is erase the memory.

    To enable this serial programming mode, you need to play with P32 (pin 20) … I wonder if that’s put out to the same pads as the RX/TX?

    There looks like a loophole in looking at the code, though – if you desolder the chip, you can program it in EPROM emulation mode - and, read it, too, but I’m not totally sure. If that’s the case, we can reverse the code - it’s not that much code.

    IF ANYONE HAS A DEAD ONE OF THESE, I’LL HAPPILY TRY TO DUMP THE ROM! Mine’s in perfect condition & not ready to break it yet…

    Also cool is that the Fluke 411D internally looks exactly like your Prexiso … from the IC layout to the screen icons. I found the Fluke for sale in Boulder, so I might get that and chance it.

  • Product COM-09433 | about 4 years ago

    Nice little card & the price is right!
    First, a quick clarification: the card enters the USB side of the dongle (the metal side). This makes sure that the card cannot fall out when it is plugged in to a computer. The plastic side has a little slot (visible in the pics above) that you put your fingernail in to eject the card. The only drawback is that you can’t connect the MicroSD sniffer because it is too long.
    Here’s the device info:

    Current required: 500mA

    I can’t confirm it, but I think that’s how it works. The I&Q data is converted to -1 (0xFF) / +1 (0x01) and isn’t bit-packed in to bytes.
    … still working on writing my mac driver for this device … haven’t tried the windows driver yet.

  • Product CLS-09016 | about 5 years ago

    I thought the forums might be better able to handle the 3+ months of dialogue we’ll probably have on this subject, so I started a thread.
    I kicked it off with a photoset from my walking tour of the course.
    Looking forward to the competition!!
