A long press on BTN1 will shut down the display and controller. This is a delay for the long press in [ms].
If set to 0, the shutdown functionality on BTN1 is disabled.
This feature requires HW functionality called "flip-flop" to be enabled in the display and controller. (default in standard configuration)
main_scr_opts
Bitwise parameter
Using this parameter, you can choose which main screens are available to the user.

| 1 | 2 | Horseshoe speed |
| 2 | 4 | Horseshoe current |
| 3 | 8 | Speed and horizontall current bar |
| 4 | 16 | Stopwatch |
| 5 | 32 | Consumption graph |
main_scr_opts = 17 (1 + 16) means that the user can switch only between the main screen and the stopwatch screen.
sub_scr_opts
Bitwise parameter
Using this parameter, you can choose which sub-screens are available. Sub screen is the one-line text at the bottom of the screen.

in_btn4
The display expects 4 buttons for control. One of them is external. The value of this parameter is the ID of the input for the external button.
The value must be the ID of the GDIN input on the display.
| ID | Name |
|---|---|
| 16 | GPIO0 - default value |
| 17 | GPIO1 |
| 18 | GPIO2 |
BTN4 is used as a map change button, or stopwatch start/stop button.

If you set this value to something other than 0, the display will simulate the controller connection. This is useful for testing the display without the controller.
| Value | Description |
|---|---|
| 0 | No simulation |
| -1 | Simulate connection |
| -10 | Freeze the simulation |
| Positive value | Simulate LYNX controller with given mode |
Permanents
These permanents are for storage user settings.
If you want to change these values, use the display menu.
mph

1 = mph 0 = kph
main_scr_id

sub_scr_id
The ID of the current sub-screen. After the display reboot, it is restored
