Connecting unused pins on the VNC1L?

(1/1)

AndersG:
Simple question: If I use a VNC1L as an USB to SPI bridge, do I need to connect the unused pins or can they be left floating? I noticed that on the VDIP-1 board there are 100k pullups on ADBUS 0..7 and ACBUS 0..4, but not on BDBUS 0..7 and BCBUS 0..3.

Answer:  The unused pins on the VNC1L can be left floating.

Also keep in mind the VNC1L only offers “managed mode” SPI Slave functionality, while the VNC2 supports both SPI Master and SPI Slave in unmanaged mode.
