VirtualMatrixPanel::_virtualResX - Not initialized when using NO_GFX #594

Closed netmindz closed 1 month ago

netmindz commented 7 months ago

VirtualMatrixPanel::getCoords expects to use _virtualResX and _virtualResY to be defined, but these are only defined by VirtualMatrixPanel::setRotation which is not called by default

You can work around the issue by calling fourScanPanel->setRotation(0); otherwise, you just get no output
