AVR RRD works

Browse Source 
LPC1768 VIKI2 & RRDFG are working

looks like all SPIs are working

library change

sh1106 locks up

fixed lockup, started I2C SW com

pretty

re-org

restore a few files

make library happy

switched HAL version of rrd

fix travis error

travis error fixes

another travis fix

cleanup

minor update

one more

correct spacing in platformio.ini

Special pin usage:
U8G_PI_I2C_OPTION additional options
U8G_PI_A0_STATE used to store the last value of the command/data register selection
U8G_PI_SET_A0 1: Signal request to update I2C device with new A0_STATE, 0: Do nothing, A0_STATE matches I2C device
U8G_PI_SCL clock line (NOT USED)
U8G_PI_SDA data line (NOT USED)
U8G_PI_RESET reset line (currently disabled, see below)
Protocol:
SLA, Cmd/Data Selection, Arguments
The command/data register is selected by a special instruction byte, which is sent after SLA
The continue bit is always 0 so that a (re)start is equired for the change from cmd to/data mode
