The Evaluation Kit includes an OLED graphics display. Features:
|
||||
|
||||
- RiT P14201 series display (www.ritekdisplay.com).
|
||||
- 128 columns by 96rows
|
||||
- High-contrast (typ. 500:1)
|
||||
- Excellent brightness (120 cd/m2)
|
||||
- Fast 10 us response with 128 x 96 pixel resolution.
|
||||
|
||||
The OLED display has a built-in controller IC with synchronous serial and
|
||||
parallel interfaces. Synchronous serial (SSI) is used on the EVB. The SSI
|
||||
port is shared with the microSD card slot.
