License: BSD
Arduino library for OLED displays driven by the SH1107 chip. Communication via I2C. Wraps Adafruit_SH130x (https://github.com/adafruit/Adafruit_SH110x). Tested using a Pimoroni Mono OLED Breakout (1.12" 128x128 pixels) and ESP32.
| Node | Description |
|---|---|
| 04-example-invert-display | A filled circle will be drawn in the centre of the display. Every two seconds the display colour will be inverted. |
| 06-example-chequerboard | A chequerboard will be drawn on the display. |
| dim-display | Dim display. This has an immediate effect on the display, no need to use the send-buffer-to-display node -- buffer contents are not changed. |
| draw-circle | Draw a circle. Writes data to display buffer. To show content of display buffer on screen use node send-buffer-to-display. |
| draw-pixel | Draw a pixel. |
| draw-line | Draw a line. Data written to display buffer. To show content of display buffer on screen use node send-buffer-to-display. |
| 03-example-rotate-display | Text will be drawn in two different directions. |
| 05-example-grid | A grid will be drawn on the display. |
| 01-draw-text | Four lines of text will be drawn. |
| draw-text | Writes string to display buffer. To show content of display buffer on screen use node send-buffer-to-display. |
| draw-triangle | Draw a triangle. Writes data to display buffer. To show content of display buffer on screen use node send-buffer-to-display. |
| get-display-dimensions | Get dimensions of display in pixels. |
| invert-display | Enable or disable display invert mode (white-on-black vs black-on-white). This has an immediate effect on the display, no need to use the send-buffer-to-display node -- buffer contents are not changed, rather a different pixel mode of the display hardware is used. When
enabled, drawing BLACK (value 0) pixels will actually draw white, WHITE (value 1) will draw black. |
| 02-example-draw-shapes | Draw shapes in proportion to display size. |
| clear-display | Clear contents of display buffer (set all pixels to off). Changes buffer contents only, no immediate effect on display. Follow up with a call to send-buffer-to-display, or with other graphics commands as needed by one's own application. |
| draw-rectangle | Draw a rectangle. Writes data to display buffer. To show content of display buffer on screen use node send-buffer-to-display. |
| draw-rounded-rectangle | Draw a rounded rectangle. Writes data to display buffer. To show content of display buffer on screen use node send-buffer-to-display. |
| init | Initialize display module. |
| rotate-display | Rotate display. |
| send-buffer-to-display | Push data currently in RAM to display. Drawing operations are not visible until this function is called. Call after each graphics command, or after a whole set of graphics commands, as best needed by one's own application. |
| sh1107-oled-i2c-device | Create SH1307 OLED device. |
