Run the program and verify that a white bar is shown on the display. Now complete the rainbow
function to show 8 differently colored bars on the display.
Explore the other drawing primitives in the draw.c/h file.
Some possible improvements of the code base:
 Increase the speed of the SPI bus to 6MHz (originally 1.5MHz)
 Test the ssd1351_fadeIn(), ssd1351_fadeOut(), ssd1351_verticalScroll(),
ssd1351_horizontalScrol(), ssd1351_deactivateScroll() functions. Examples of usage can
be found in the software package that came with the OLED display module
