My ZUMspot functions perfectly as a DMR hotspot.
(purchased from HRO USA)
The OLED shows MMVDM logo when idle.
The OLED displays DMR activity info during calls.
But the screensaver never activates.
I am running on RasPi Zero/W with ZumSpot:
Pi-Star:3.4.17 / Dashboard: 20200221
Detected MMDVM_HS (GPIO): /dev/ttyAMA0 (ZUMspot-v1.4.16 20190211 14.7456MHz ADF7021 FW by CA6JAU GitID #8cf46ca)
my /etc/mmdvmhost has section
[OLED]
Type=6
Brightness=0
Invert=0
Scroll=0
Rotate=0
Cast=0
LogoScreensaver=1
These OLED functions DO work when configured:
Invert= 0 / 1 (wt/blk, blk/wt)
Rotate= 0 / 1 (0, 180 flip)
These functions do NOT work:
Scroll=
LogoScreensaver=
I tried updating..
I get ‘no updates found’ when update or upgrade.
I am not sure where to look. Driver? Firmware? Hardware?
Appreciate the help.
Thanks,
Greg
OLED 1.3” screensaver on ZUMSpot does not work.
Re: OLED 1.3” screensaver on ZUMSpot does not work.
Right. I am definitely unfamiliar with the meaning of those parameters and I do appreciate your explanation.
What puzzles me is: if the point of screensaver / scroll is to prevent OLED pixel wear, why leave the MMDVM logo burning practically forever when the hotspot is idle. In my case DMR mode is active sporadically maybe a few minutes during calls so acting to minimize display burn then doesn’t seem worth it.
I will try to take a look at MMDVM source code but I suspect it’s above my ability to modify or improve.
Thanks again for your help.

Re: OLED 1.3” screensaver on ZUMSpot does not work.
I upgraded my hotspot to the latest image Raspbian "Buster" Pi-Star:4.1.0 / Dashboard: 20200406. (Pi-Star_RPi_V4.1.0_26-Mar-2020.zip) Now OLED is working as I wish. OLED is Full dark when idle, displays DMR info during calls / listening.
