It's possible to export to miniMAD through LAN, that's actually the way I'm using it for development and testing.
As for the splashscreen it's a bit hacky but it may turn to a proper feature in the future.
First, the miniMAD must be running and connected through ethernet to the same network as your computer so you can access it through SSH (the miniMAD IP-address appears on top left of the screen when pressing YELLOW while holding BLUE).
Let's assume your miniMAD is started and its IP-address is 192.168.1.12
- In the Terminal
copy/paste/edit the following line to kill the miniMAD application:
ssh pi@192.168.12 "sudo killall -9 mad_raspi"
(type "raspberry" when asked for a password)
- In the Finder
press Cmd+K to bring the "Connect to Server" window.
copy/paste the following line in the "Server Address:" input-box:
afp://pi@192.168.1.12(type "raspberry" when asked for a password)
Your miniMAD's "MINIMAD" volume should now be accessible on your Mac.
When opening the "export to miniMAD" dialog in MadMapper, and you should see the miniMAD's SD-card available for export.
You can now export your mapping the same way you usually do.
- Back to the Terminal
copy/paste/edit the following line to to reboot the miniMAD, hopefully playing your new mapping:
ssh pi@192.168.12 "sudo reboot"
(type "raspberry" when asked for a password)
