You may have already seen previous posts about the Murum Lux (Wall of Light) including a post about the human interface portion. Today’s post refers to the Ethernet portion that Josh wrote about. Using two P-401 Ethernet modules by a Spanish company named IPLogika (one on-board his “e-field” box, and one on-board the Panel/Display board) he created a network by which he communicated the human interface gestures from the gesture panel on the E-field box to the Display.
P.S. Keep an eye out for his tip on using one module to aid in debugging!
