.... arrived today, and were up and running, working perfectly, in under 15 minutes: http://git.rhombus-tech.net/?p=eoma-firmware.git;a=tree;f=eoma68/arduino_uno...
i used a makefile that was easily found with a google search "debian arduino uno makefile", followed the instructions _in_ the makefile, created a blink test, ran it, ran "make upload" and it worked. total time: well under 3 minutes. next was the SPI-based LCD, soldering took a few minutes, copying the library files into the main directory a few more - done.
i've now modified the adafruit source code so that it can do 9-bit SPI bit-banging, by setting "IM1=0" (shorting that to ground) and i'm now in a position to begin two-way testing of the adafruit LCD with an STM32F072, and the yunlea HX8357D LCD with the arduino uno.
this is a heck of a lot quicker than messing about with both unknown hardware and unknown software.

Looks good, what is the price for this lcd?

from yunlea? $25 including a capacitive touchscreen pre-glued as a single unit.
from adafruit? $40 including a *resistive* touchscreen on the front, pre-glued as a single unit.
the yunlea has 2 connectors, a 39-pin 0.3mm pitch staggered FPC and a 12-pin 0.5mm pitch connector for the touchpanel.
the adafruit one has all sorts of break-out pins (2.54mm pitch), has level shifters on-board (for when you use it in 8-bit parallel mode and the incoming voltage is different from what the LCD prefers), as well as an LCD backlight current-controlled step-up converter already on-board.
