Redefine the preprocessor definitions for PICKET_SHORT, NUM_FENCES, SEG_DELAY.
Make sure that you are utilizing atleast one driving waveform by defining either
USING_PICKET_FENCE, USING_SLIDESHOWS or USING_GLOBAL_UPDATES.
Step 3: Testing: Causing an update
Once Step Step 1: Defining the segments and Step 2: Positioning the driver function and delay have been
completed, set some of the elements of the nextDisplay array to 1 and set variable updateRequest to 1.
NOTE: Ensure that your timer interrupt is running. This should result in a physical change on the EInk
display screen. If needed, make a call to ClearDisplay to clear all segments on screen. This is preferred
after power up.
Step 4: Using the presentation layer
The presentation layer provides a convenient way of selecting which segments to turn ON/OFF on the
EInk screen for different purposes e.g. displaying numbers or alphabets. Each display can be logically
viewed as consisting of different zones as shown in the figure below.
