RA8875 for Beaglebone

Post by claudioalmeiida »

Hello guys, I'm starting with the BBB, currently using Arduino and bought the lcd controller:
https://www.adafruit.com/products/1590

Using libraries:
https://github.com/adafruit/Adafruit_RA8875
https://github.com/adafruit/Adafruit-GFX-Library

My question is, someone has already ported these libraries for Python and used in the BBB or Raspberry? if not, is this possible to do?

I know of no one who has done that.
Theoretically, it's possible - the RA8875 is just an SPI device.

OK, now I'm confused: I thought the BBB had an LCD controller built in.

The HDMI output is nice - but I have an original Beaglebone. No HDMI !
I came here looking for suggestions on how to connect the Adafruit 5.0" screen:

I was hoping to find a Beaglebone version of the Gameduino2:

I thought, at least, you'd have a "Cape" that adapts the Beaglebone to the 40-pin connector your LCD's all have in common.
Oh well. I may have to design a Cape from scratch.

So tell me, please: would a 'Bone LCD cape need a controller, like your RA8875 circuit?
Or just the current source, like on your board, to drive the LED backlight?

I think not exists this "cable", you have to use a driver, type the RA8875.

The RA8875 uses the SPI pins (miso, mosi, sck, etc...), I created this thread looking for someone who has ported the library that exists in Arduino "C" for Python, but by the way no one did, then I went to learn Python, and yesterday I finished creating the library to work on the RA8875 driver BBB or even Raspberry PI (with some modifications of course).

Soon I will post here.
