Elements of page

OLED

  1. Configuration form with fields for enabling OLED display support, setting the I2C bus frequency, and content of lines.
  2. List of readings from the LC3 that can be shown on display.
  3. Virtual OLED function.

OLED display configuration

The OLED display is divided into 4 lines, each up to 16 characters. They may contain the characters a-z, A-Z, 0-9, =, % and a space.

You can also insert values from sensors, just like in the HTTP client, using a special format. More information on this here.

Warning

Be careful not to enter more than 16 characters in 4th line, because the display will only display characters after the 16th position from mentioned line.

For example, 12345678901234567 in line 4 will only display 7 on line 1.

Warning

Insert at least one space in empty lines. Otherwise, the displayed content may be wrong.

For example, a clean line 2 will cause that the display will show lines 1, 3, 4, 1.

Info

The display initialization is carried out at the LC3 startup and when it is turned on in the OLED tab. Therefore, the display must be connected before the LK start or if later connected, you must enable its operation (if it was already on, you must turn it off and on again).

Virtual OLED

Available since HW 3.5+ SW 1.31

Virtual OLED

Experimental feature that displays content of OLED display in browser. Just fill in the form and visit the page via one of links in the section on page. There is no need for actual OLED display and the page can be viewed without signing in. The idea is to use it as remote display for LK - device with display only needs to view this page in browser.
