Kleines Breakout mit einem 0,96" OLED und microSD Sockel.
Das Display hat eine Auflösung von 96x96 Pixel und eine Farbtiefe von 16-Bit.
Zur Ansteuerung stehen SPI (3 oder 4 Pin), sowie ein paralleles 8-Bit Interface (8080/8060) zur Verfügung.
We love our black and white monochrome displays but we also like to
dabble with some color now and then. Our new 0.96" color OLED displays
are perfect when you need an ultra-small display with vivid,
high-contrast 16-bit color. The visible portion of the OLED measures
0.96" diagonal and contains 96x64 RGB pixels, each one made of red,
green and blue OLEDs. Each pixel can be set with 16-bits of resolution
for a large range of colors. Because the display uses OLEDs, there is no
backlight, and the contrast is very high (black is really black). We
picked this display for its excellent color, this is the nicest mini
OLED we could find!
This OLED uses the SSD1331 driver chip, which manages the display. You
can talk to the driver chip using either 3 or 4-wire write-only SPI
(clock, data, chip select, data/command and an optional reset pin) or
standard 8-bit parallel 8080/6800 which also permits reading pixel data
from the display. Our example code shows how to use SPI since for such a
display, its plenty fast. Inlcuded on the fully assembled breakout is
the OLED display and a small boost converter (required for providing 12V
to the OLED) and a microSD card holder. Our example code shows how to
read a bitmap from the uSD card and display it all via SPI.
The logic levels for the microSD ard and OLED are 3.3V max. In order to
make this breakout usable for bidirectional 8-bit and SPI interfaces, we
left out an on-board level shifter. However, we include a DIP chip
75LVC245 8-bit level converter chip and our tutorial shows how to wire
it to an Arduino so that you can use the breakout with 5V logic such as
that of an Arduino. If you have a 3.3V logic level microcontroller
system, you can skip the level shifter.
Of course, we wouldn't just leave you with a datasheet and a "good luck!" - we've
written a full open source graphics library that can draw pixels,
lines, rectangles, circles, text and bitmaps as well as example code and
a wiring tutorial
. The code is written for Arduino but can be easily ported to your favorite microcontroller!
