Hello PICs!

We are going to use PIC microcontrollers to control our robot, and we are going to program them in assembly (yay for low-level coolness and total control!).

We plan to use a PIC16F648A (256 bytes of RAM for us to use, not much, just for it to be more exciting) as the main brain. It would be in charge of solving the sudoku and controlling (asking for information, and receiving information from) other, smaller PICs (12F675).

We had our first meeting (the trigeeks at my basement!) last Sunday, and since then we’ve started working harder!

Now I’m going to show you some videos so you can see some of what we have been doing. Follow the links (click on the videos) for a more detailed description of what’s going on in them.

Our very first test with a PIC (we had never used one before!):

Dealing with 7-segment displays:

And finally, our current masterpiece in terms of hardware. A first prototype of the colour sensor that will be used to detect different pieces (1-9). Also, note that here we have two PICs working together. =)

    Omgogmog PICs plx?

    It seems we are going to use only those 2 models of PIC unless we need to add some fancy new way of doing things :) then we would seek another model that works as we spect it to.

    More videos to come! When the DB exam passes I’m gonna work on the 2nd prototype of the color sensor and let you guys know, with a video of course xD oh and also on the electromagnet omg

    Cya peepz.

    SPECTacular comment, Minolo. Yeah, once the DB (DataBases) exam has been done, we’ll have much more free time (that means 29th of April to you readers).

    Really cool… currently working with a 7 segment display…
    Excuse me about my ignorance about PICs. but how do you put the program into the PIC?
    Do you have a specific hardware for write from your pc?

    xD I’ll follow your progresses geeks!

    Nice question, GeuS. =)
    Minolo is preparing a couple of posts that will clarify the process of programming the PIC.
    I hope these posts will be available soon. =D
