10. Recommended Software Initialization In order to ensure the reliability and stability of the module, the module must be initialized using the following code, malfunctioning of the module may occur and the reliability of the module may deteriorate if the module is used beyond the initialize code. You can download the Demonstration Code written for Seeeduino v4.2 set to 3.3v (Important!). This code uses the 4-wire SPI mode of the display; actually, only 3 wires since MISO is unused in this example. Page 20
