The documentation in UG-587 has some conflicting information with respect to a diagram on the same page (see attached). Can you clarify when pins pertaining to the LCD driver interface I can leave unconnected?
Did you mean to attach a file?
We have an example board for LCD driver (Schematic on this Link). Maybe you can refer to this?
Oops, here is the file.
VLCD_FLY1 and VLCD_FLY2 can be left no connect. Those are not connected to VLCD on Figure 81 of the user guide.
UG-587 p. 279 says to connect VLCDVDD to VCCM when the segment driver is "NOT USED"
VLCD13 and VLCD23 are floating on the diagram, its also not connected on the ADUCM350EBZ Board
Oh, I see what you're saying now. (I was looking at it wrong, see attached). I will add my LCD display and leave VLCD_FLY1, VLCD_FLY2, VLCD13 and VLCD23 all floating, while disconnecting VLCDVDD from VCCM and hang a 0.47uF cap on VLCDVDD.
