Tiva TM4C1292NCPDT 8x8 R click matrix

Other Parts Discussed in Thread: ENERGIA

Hi,


I am trying to implement a tool with which I am able to contact GPIO or SPI through ethernet.

My LED matrix (via boosterpack) should be able to show numbers, letters and I have to manipulate some registers for the brightness and scanrate. The input through ethernet is coming from another microcontroller. (yes we have to agree on a protocol etc.). But I guess for now, I can test that with nc.exe. I am currently starting with it and searching for documentations, code examples or smth. like that. Maybe on of you guys (definitiely more experienced than me :) ) can give me some advices how to start. Maybe one of you had some experience with such implementations.

Thank you!

Davor

    Hi,

    In old DOS days, nc.exe was the name of Norton Commander application - doubt it is the case here - so can you be more precise about this name?

    Suggest also to split your project in smaller parts and make/test separately, until you have all functions/routines needed to test the whole. 

    As you claim to use a boosterpack for LED matrix, it is not clear if you have a working program for that. Start with such small program in the case you do not have it. Completely ignore the Ethernet at this stage.

    Hi Petrei,


    sorry. What I´ve meant was netcat. It should be possible to send data (characters) via netcat to my server through a protocol, port and so on. You are absolutely right, I don´t have a sample program to check this via boosterpack. It would help if I had anything just to start with it. I´ve found something on http://www.libstock.com/projects/view/443/8x8-click-example .  Maybe I could test with this. Testing with the LEDs on the board itself is working and I have already implemented some applications for that. But through RTOS, boosterpack and this module is something new for me :)

    Hello,
    i have also to work with a LED matrix, and in addition to that with a joystick.. do you have your project solved and maybe the code to help me?
    i am going to control the process of the order of the letters, and also upper/lower case letters with the joystick.

    Thanks,

    Hello Barbara,

    I have replied to your other post that is similar (e2e.ti.com/.../1876978 although this thread adds the additional complexity of the LED display. My same advice applies as posted in the other thread. Note that this is not a forum for exchanging answers but we will provide guidance when/if we can. Also note that this is not an E2E for Energia if this is the development tools you are or plan to use. The forum for Energia is located here: forum.43oh.com/.../. There is even a folder specifically for Tiva in the Energia Forum if you need to use it.

    Chuck - surely "not" your doing - but just HOW are novice posters to "know" what is welcomed vs. shunned?

    For years others & myself have suggested, "Poster Guidelines" - once again - your firm's belief, "No guidance required" proves a failure!

    I stand w/this poster - not w/you (vendor) - for IMPROPERLY NOTING (i.e. noting NOT AT ALL) this forum's intent.

    "Shifting blame" from one's own weakness (zero guidance) to hapless, novice posters - proves not "best ticket" to forum success...

    CB,

    I was simply replying to the following statement in Barbara's post...

    "i have also to work with a LED matrix, and in addition to that with a joystick.. do you have your project solved and maybe the code to help me? "

    My intention was to discourage the easy path to getting the project working which bypasses the learning opportunity provided by the project. Certainly, if the original poster and Barabara wish to exchange tips and/or the full project there are no specific rules that prevent this on this forum.

    Note that the 'click' kits are something new that don't have a lot of use in this forum so far so there is little information on them. They would require a custom HW interface due to their product specific pinouts but this can be done with jumpers or a breadboard for lab purposes. There are SW examples written for some legacy Stellaris devices that, as you noted, were never fully released into production but contain similar IP as used on existing TIva devices so should provide a firm starting point for developing their own applications.

    Yet again Chuck - you went (beyond) "simply replying" did you not?   I'll (repeat) here your exact quote, "Note that this is not a forum for exchanging answers."  

    Again - how, where, when is this to be noted?   There are NO Forum Guidelines - thus the forum descends to, "wild west."   Do you (realistically) expect others to find this isolated post - soon to "rotate off into forum back-bench oblivion?"

    Most of your responses are accurate and to point - yet twice this day you've ventured onto shaky ground - and those ventures HAVE been noted!  (and are not especially helpful - nor based in reality...)  

    While Amit has long been the forum's "hero" - you're a great addition.    Posters Robert, f.m., Petrei & I have been here awhile - the "accuracy quotient" of vendor response is high - and I believe it in your "best interest" to avoid "reaches" - where the facts argue SO strongly - against your "gratuitous" additions...
