I decided to share my first code using the OLED C in the Curiosity board as an example as I had a couple of hours debugging why it was not working out of the box, and of course the only existing examples are for MikroElektronika boards, I could not find anything for the MPLAB X with an 8 bit PIC. I also added a print function to put text to the screen, so the OLED C can serve future projects as a debugging/logging interface, Curiosity itself has limited capabilities for onboard debugging sometimes.

So my biggest problem was to find the correct SPI clock settings. SEPS114A requires idle:high, active:low clock pulses and MPLAB X generates the opposite setup by default. Of course deeper knowledge of the SPI and/or the SEPS114A would help, now I have both :-)

LED D4 is for debugging purposes, has no function for the SPI or for the SEPS114A.

What is still missing:
- the text is rotated 90° to the right, some rotation feature shall be added for positioning
- better string handling functions with line breaks, etc.
- more fonts
- delay_ms is not really 1ms delay, never measured how long is it exactly but serves well :-D

1.1.0.0 is here with colors, screen orientation setting, smaller font 5x5 (own design), new file structure for easier implementation to new projects.
