elektrax:
about lcd graph library :This library uses an SPI-like software protocol and does require exclusive access to the pins used. You will not be able to share pins with other SPI devices.
well how did i not notice that ...
I used rinky dink library as adafruit was not working for me for bitmaps.
Switched to adafruit and the issue persists, if i use the adafruit software init or hardware init it still persists.

It talks of the same issues as me but i see its from 2011 and further adafruit LCD8544 now has both software SPI and hardware SPI support. or am i wrong?
