10.1 Introduction
Included in the sample code section are two examples of programing the SED1374. The
first sample uses the HAL to draw a red square, wait for user input then rotates to
SwivelView mode and draws a blue square. The second sample code performs the same
procedures but directly accesses the registers of the SED1374. These code samples are for
example purposes only.
