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.inipull/1/head
