.... 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.
