If user input is required the official LCD160CR display with touch overlay should be used, with a GUI available here or for large 4.3" SSD1963 displays this one.
Display drivers are provided for Adafruit 1.5, 1.27 and 0.96 inch colour OLED displays. There is also the official SSD1306 driver for monochrome OLED displays. These may be used:
- Alone (inheriting the framebuf graphics primitives).
- With the CWriter class to display text in arbitrary fonts and colours.
- Or with nanogui which builds on the CWriter class.
The meter levels, LED text strings and colours change dynamically as the data changes.
Analog clock. The widget is actually capable of displaying vectors of varying length, as straight line pointers or as arrows.
The plot module displaying analog data being captured in (slow) real time.
The Nokia 5110 with this driver may also be used with the monochrome Writer class to display arbitrary fonts, but the resolution of these displays is probably inadequate for the GUI.
