NCV78343 Series Pixel Controller
Evaluation Board User's Manual
NCV78343EVBUM
The NCV78343 Evaluation kit demonstrates functionality
of the NCV78343 pixel controller. The board supports two devices
(with possibility to chain up to 32 devices) and up to 24 individual
pixels. UART as a communication protocol is available on both CAN
and M−LVDS physical layers, which allows to simulate different
system architectures directly on the board. On board slot for
LED driver can be optionally fitted with boost−buck converter
NCV78763R1DAGEVB.
Both devices are controlled by the dedicated ONMCU board which
is connected to the PC via USB cable. The evaluation kit is supplied
from either banana or power jack connectors. Two I/O communication
connectors for CAN and M−LVDS physical layers can be utilized
to connect several pixel controller devices in a chain.
