pyEfis won't display to OEM LCD screen #101

Closed Snowflake6 closed 3 years ago

Snowflake6 commented 3 years ago

I'm trying to run the pyEfis package on a Pi4 with the Raspberry OEM 7" LCD touchscreen. I'm not having much luck, however.

I have fixgw running (using fixgw.py because fixgw fails, issue logged under fix-gw). I have confirmed fixgw running using fixgwc ("status") and by setting fixgw up to run as a gui. When I start pyEfis, the fixgw gui shows that something has connected to it, but nothing comes up on the display. An error message is reported on the pi regarding the geomag module (I have no gps plugged in yet).

Is the pyEfis package set up to not work with an LCD connected through the display connector? Does it have to be via HDMI?

Update: Disconnected the LCD screen and plugged in an HDMI cable instead. Same result, pyEfis won't bring up an EFIS display. It seems to be running as fixgw shows activity and the pyEfis.py script doesn't die. But nothing comes up on screen. So this is likely not related to the use of the OEM LCD after all. There must be something else wrong with the default install of pyEfis.py.
