Hi !

I used ucblib (with ili9163_18x128x128_hw_spi) with a nodemcu v1.
- Module is this one, bought from aliexpress : http://www.aliexpress.com/item/Consumer ... 60001.html
- Firmware is NodeMCU 1.4.0 build 20151006 powered by Lua 5.1.4 on SDK 1.4.0 with li9163_18x128x128_hw_spi module
(I used Marcel Stoer's docker to build it)

Everything look fine except that a part of the screen looks bugged (see attached picture) and can(t be erased/drawn/accessed. It stays the same even if I restart the mcu and/or the screen. When I run the Graphics test examples provided with ucglib I had one occasion when the screen was fully used, then it came back to the situation with the screen only partially usable.

Any idea what it could be ???

Found it ! There is a bug in the library if you use the red PCB (the cheapest). To have it work you need to comment the "+32" and "-32" in ucg_dev_ic_ili9163.c in lines like "ucg->arg.pixel.pos.y += 32;"
