GUI with touch on the 7" Pi display?

Take a look at this neat chip, the RA8875. This shows the potential of putting all the low level drawing functionality on a dedicated chip. Sort of a "MCU gpu". All the functions are implement via either serial, SPI, or i2c. Imagine this same type of arrangement with an fpGui "back end". The Rpi can serve as a replacement for the RA8875 chip and bring it to a full size monitor!

That's the best SDR display I have seen.
SDR has just gone on my list of things to make one day.
Use a Zero and USB TV dongle?
Don't think we can use Ultibo with LInux SDR driver, yet?

RPF have made it a bit hard to use their 7" by putting secret sauce on it.
Do not want to RE the Atmel touch chip etc.

Could we bit bang a TFT parallel interface on the GPIO for 4 - 7" TFTs?
Ron has shown SPI LCDs and we have HDMI.
Off topic now.

You can have a bank of 20 of the and run them with an Arduino UNO or an attiny85 even. Slowly, of coarse but they are "autonomous". Simply initialize them and pass them "op codes" over i2c, SPI or serial/uart. I actually have the Ra8875 and also the SSD1306 Oled screen in the works. Porting these over to freepascal is a quite simple. Maybe I can work on them over the weekend. Anyone have an SSD1306 Oled to test this with by chance? I couldn't get the knock-off/el cheapo one I have to initialize.

Yeah, we have drifted off topic. I will start a new thread/s tomorrow.

Not sure we we linked this one
http://oberon.wikidot.com/start

Just had a look at the source?
OLR has native mode support for ARM, MIPS, X86.

Just extracted both sets of files to the same folder and ran ./oberon.
Fired up real quick in my Celeron Duo Linux box.
Looks just like the pictures, left/right buttons, third mouse button (scroll wheel) takes a bit of getting used too.
Have not tried it on Pi yet.

Did not have much of a play, feels like I need a brass and wooden keyboard.
Change the default colours to dark brown text on parchment?
