FBTFT for BeagleBone Black

[nejemia]

Dear NOTRO:
I am delighted with the fbtft running on Raspberry-
However, I think I have reached the limit of Raspberry capability to run several "heavy" apps.
I wonder if you can think in having the same fbtft running in the BeagleBone Black board. It is far fast and powerful than Raspberry, also, good support from TI.
Let me know, and if I can be of assistance to test releases, will be a privilege.
All the best and do not hesitate to contact me directly at - nejemia@gmail.com

It is a long term goal to make an image for the BeagleBone Black. I have had one lying on my shelf for a month now.

But at the moment I have some things I want to see in FBTFT before I move on to another platform.

Another challenge, is that a new platform brings more research, testing and support requests, which takes time.

If someone doesn't step up and take responsibility for FBTFT on BeagleBone, it can take some time before we get there.

Dear Noralf, thanks for answer. I have the exact same impression. Raspberry is nice, but once "pushed" with some high level apps, the uC starts to cry. I am looking to several different boards, Olimex, Minand (Allwinner A10), Beagle and others. All of them fantastic pieces. However, Raspberry is by far the better supported and with 1000s of apps. Your "fbtft" is one of the most brilliant app I found, this is why I was enthusiastic in porting the concept to other boards. Well, lets see in the future how goes it.
QUESTION: Do you have a ready to install .img for the Raspberry suporting the HY28A Display ? Again, thanks a lot and my congratulation Master.

The latest image has support for HY28A.

Obviously you need to follow the best path and work as your schedule allows, but (and I am sure you that but coming)... I would really really like to see BeagleBone Black support much sooner than later. So just another vote for the beaglebone here ;)

I am using the BeagleBoneBlack and have got a couple Sainsmart LCD screens on order, a SPI interface

From looking over your driver, I think that at least for GPIO it should just be a matter of changing the module load parameters to specify new ones - while SPI may work out of the box.

I will give them a try and fiddle with the drivers when they come it. If I get it working, would it be better for you if I place the changes in a new branch specific to the BBB, or try to consolidate them?

Ideally I'd like to rewrite things to use DTS files, but there is no reason not to get it working as is initially.

My intention is that FBTFT should work on all platforms that satisfy depends on FB && SPI && GPIOLIB

Ideally I'd like to rewrite things to use DTS files, but there is no reason not to get it working as is initially.

I'm currently trying to get Device Tree working on the Raspberry Pi. When I have done that, I will add DT support to FBTFT.

I have started a wiki page containing a list of the drivers I have tested with the BBB: https://github.com/notro/fbtft/wiki/BeagleBone-Black

Hello,

I have BBB and SSD1289 LCD module (TFT_320QVT). Sory for lame question. Should I need use this (https://github.com/notro/fbtft/wiki/SPI-interface-circuit) interface to connect LCD to BBB or connect LCD direct to gpios ? Thx.

[notro]

I have BBB and SSD1289 LCD module...

Answered here #65, please don't double post.

Since there is a Debian (Wheezy) Package available since May for the BBB maybe there is hope to get an easier port of your excellent work... ?

[notro]

I don't have time to make packages for BBB, but now it's easy to build FBTFT out-of-tree: https://github.com/notro/fbtft/wiki/Out-of-tree-build
