S1D13705 Programming Notes and Examples
X27A-G-002-03 Issue Date: 02/01/22
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.
