FAQ: LCDs for Servers

Question from our tech forum:

I’m looking to put LCDs on my new servers, which are pretty significantly complex even before you get into the software on them.

This customer had a complex set of requirements for LCDs to be used in a server set up.


  1. Need to drive four LEDs, and need 14 pinouts.
  2. The host data needs to get fed from USB as it sits, and gets pretty fancy.

That is a potentially tall order, but we have a solution!

Our Answer:

Everything you want is possible with the CFA735/835 hardware and a few helpers.
