Actually with lcd documentation is a problem, because I do not understand values in data sheet or those are just in different naming(page 7). For instance what are actually values for <h_front_porch> <h_sync_pulse> <h_back_porch> and <v_front_porch> <v_sync_pulse> <v_back_porch> ? datasheet https://...

Re: lcd library to drive 18 rgb data

Yesterday I moved lcd from msp to raspberry pi2.
this is my progress so far https://youtu.be/BxgXBjOAdfg
Looks like with GPIO library I dont have enough speed. vsync black line is still seen. I will need to try some C libs like Wiring Pi.

Re: lcd library to drive 18 rgb data

That looks like it may be driveable via DPI (Display Parallel Interface). Have a search on here for DPI, Adafruit Kippah, or VGA666 as they all use the same hardware block. Other guides to using it are at http://blog.reasonablycorrect.com/raw-dpi-raspberry-pi/ or https://learn.adafruit.com/adafruit...
