Full display refresh

In order to protect the display of the device from the so-called "ghosting", where an image becomes permanently imprinted on the e-ink display, we have to refresh it fully every max. 24 hours. If you decide, you can lower the full-refresh period, which can remove some dim artefacts from the display's partial refreshes.

SET

This command sets the full display refresh period.

Byte index	Hex value – Meaning
0	33 – The command code.
1	XX - Full display refresh in hours. Default value: 0x0C (12 hours)

Example downlink: 0x330A - set the full display refresh period to 10 hours.
