10 Sample Code

Included in the sample code section are two examples of programing the S1D13705. The first sample uses the HAL to draw a red square, wait for user input then rotates to portrait mode and draws a blue square. The second sample code performs the same procedures but directly accesses the registers of the S1D13705. These code samples are for example purposes only.
