EZSDK: LCD & Touch support for Beaglebone Black (BBB)???

Hi!

I was happy to hear that the latest TI Linux SDK seems to support Beaglebone Black. Unfortunately, most posts regarding LCD cape support here in the forums are unanswered.

I would like to know what Beaglebone Black LCDs are currently supported by TI's EZSDK. Especially, I would like to know if the popular LCD4 (http://beagleboardtoys.info/index.php?title=BeagleBone_LCD4) and the 4DCAPE-43T (http://www.4dsystems.com.au/product/22/125/Beagle_Bone_LCD_Capes/4DCAPE_43/) are currently supported or if it is planned to support them in the near future.

Both displays with touchscreen are currently supported in Angstrom, AFAIK they even use the same drivers. So how about the TI SDK?

Thanks in advance,

Anguel

    Hello Anguel,

    A week or so ago I was able to get the LCD7 cape working on the BeagleBone Black by using the Sitara Boot Camp LInux Board Port Lab as a reference.  Here is my code:

    0882.bbb_lcd7_touch.zip

    I haven't tried with LCD4 or the other cape you mentioned, but it should not be too hard to get them working if you use the linux board port lab as a reference.  If I get a chance, I will test them out myself and let you know the results.

    Regards,

    Josh

    Hi Josh,

    Thank you very much for the information. This sounds great. I am just getting started so I will need some time to get to porting code :) It would be great if you succeed in porting the LCDs as you already have the experience and many users are really looking for using those widely available LCDs with the BBB.

    Btw, I discovered a strange jitter/jumping touchscreen problem with the LCDs (also with LCD7) when using Angstrom. Did you observe such behavior on your port? Here is where I reported the problem:

    Looking forward to the LCD port to TI's SDK.

    Best regards,
