  • Xpress Evaluation Board

    03/02/2016 at 18:03 • 0 comments

    Some weeks ago I read this Article on Hackaday. Microchip did gave away some MPLAB Xpress Evaluations Boards. Here are some thoughts about this and the MPLAB Xpress browser based IDE. This page does not claim to be a full review just some thoughts (and I did not get paid for it).

    First as also written in the Hackaday article it is possible to get nearly set-up time free entrance to Microntroller development. It is possible to use this this board just with the online IDE and no need to download anything.

    The online IDE does work similar to the offline MPLAB X IDE. It also looks similar. But for me there is code completion missing (or at least not findable). After writing your code. You can compile it and download the hex file. But if you like to use the Xpress Code configurator you need to download some software. This should be included in the web application. Something else I did noticed is that you have the board connected if switching between two projects when using the code configurator and the online IDE.

    The code configuarator is a really nice tool for fast results. This tool was also new to me (I did work with PICs before). Because I did used PICs before, there was MPLAB X installed on my PC. The code configuarator is there also available as much smoother working plugin.

    Now to the Hardware. If there is a compiled hex file created by one of the IDEs, the programming of the board is very easy. The board is recognized as external flash drive. After copying the hex file onto it the PIC gets programmed and resets when ready. Very simple and easy to use. On the Hardware side it is very handy to have the potentiometer and four user leds onboard. Thesre is also a switch wich I did not used so far.

    I do like this board and this is a good way to learn more about PICs. So far did only use smaller PICs mostly for basic IO stuff. So this board is a good platform for further experimenting. But I will use the offline IDE the most time. The online IDE is useful if you do not use your own computer (or some small netbook) and want to change something quick.

    So faar my first expierencer with this board.

  • MEMTYPE testing

    01/24/2016 at 20:54 • 1 comment

    First test - 2016-01-24

    Today I plugged my #Memtype into my PC for the first time. Here I will write some words about the first impressions/ideas. This page will get updated when i am doing further tests.

    Positive Thinks:

    • Worked out of the box (Win7)
    • Nice and user friendly menu structure

    Negative Things

    • causes blue screen when unplugging while it was writing
      (only one time. I could not reproduce this, could have an other reason)

    Ideas for Improvements ( all meant constructive and not negative)

    • case! This could be much more handy with a case. So that you can put it on your key ring and carry it with you.
    • For testing this PCB USB plug is okay, I would replace it in a production run.
    • use right footprint for the ATtiny
    • use QFN ATtiny - this would be thinner and better to put in case
    • LED maybe dual color to indicate power/locked/unlocked

    So far to my first impression of Memetype. the next thing I will do is testing the mttoll software. And store some real data on it.

Hello Alex,

Thanks for skulling my XSBO board. I am currently testing the very first proto and it works great. I have uploaded the Schematics, PCB drawing, Gerber file and the blinky test firmware.

By the way, the PCItil project is great. I have use TIL311 in the past (many years ago). Great memory. They were really usefull and handy when it came to indicate an Hex code. I am wondering if a version with an LPC812 in XSON package would not be possible.

Grüsse aus dem Elsass.

Michel
