**bw_mode**
|
||
|
|
|
||
|
|
Sets black and white mode of display
|
||
|
|
|
||
|
|
Values [0-3]
|
||
|
|
* 0: Grayscale (default)
|
||
|
|
* 1: Black and white + dithering
|
||
|
|
* 2: Black and white
|
||
|
|
* 3: DU4 waveform
|
||
|
|
|
||
|
|
**bw_threshhold**
|
||
|
|
|
||
|
|
Sets threshold where pixel is considered white or black. If default, all pixel values lower than 7 will be cast to 0 (left), and all valuers larger larger or equivalent will be cat to 15 (white)
|
||
|
|
|
||
|
|
Values [0-15]
|
||
|
|
* 7: default
|
||
|
|
|
||
|
|
**auto_refresh**
|
||
|
|
|
||
|
|
Controls auto refresh feature
|
||
|
|
|
||
|
|
Values
|
||
|
|
* 0: disable (default)
|
||
|
|
* 1: enable
|
||
|
|
|
||
|
|
**refresh_threshold**
|
||
|
|
|
||
|
|
Global refreshes are triggered based on the area drawing using partial refreshes, in units of total screen area.
|
||
|
|
|
||
|
|
Therefore will trigger a globlal refresh whenever 2 screen areas where drawn.
|
||
|
|
|
||
|
|
The threshold should be set according to the application used. For example, evince and xournalpp really like to redraw the screen very often, so a value of 20 suffices. Other require lower numbers.
|
||
|
|
|
||
|
|
Values
|
||
|
|
* 20: default
|
||
|
|
* 60: ideal
|
||
|
|
|
||
|
|
**refresh_waveform**
|
||
|
|
|
||
|
|
Sets the waveform to use for global refreshes.
|
||
|
|
|
||
|
|
Values:
|
||
|
|
* 4: default
|
||
|
|
|
||
|
|
|
||
|
|
**dclk_select**
|
||
|
|
|
||
|
|
Controls how fast data is sent to the ebc display, allowing for a "quality" mode that reduces visible artifacts as
|
||
|
|
much as possible, with the downside of having bad latency, and a "performance" mode where speed is gained at the expense
|
||
|
|
of visual quality.
|
||
|
|
|
||
|
|
Values:
|
||
|
|
* 0: quality mode (default)
|
||
|
|
* 1: performance mode
|
||
|
|
|
||
|
|
Display refresh rate should match so that:
|
||
|
|
* quality: 5 hz
|
||
|
|
* performance: 80 hz
|
||
|
|
|
||
|
|
Refresh rate can be set using:
|
||
|
|
sway output DPI-1 mode 1872x1404@80Hz
|
||
|
|
|
||
|
|
Note that current detected maximum is 40 Hz, for some reason.
|
||
|
|
|
||
|
|
## Controls via [pinenote_dbus_service](https://github.com/PNDeb/pinenote_dbus_service)
|
||
|
|
|
||
|
|
|
||
|
|
**Refresh screen**
|
||
|
|
|
||
|
|
Can be done using the following command:
|
||
|
|
|
||
|
|
dbus-send --system --print-reply --dest=org.pinenote.ebc /ebc org.pinenote.ebc.TriggerGlobalRefresh;
|
||
|
|
|
||
|
|
Note that this requires the pinenote-dbus-service package
|
||
