Description
The STEVAL-CBP005V1 demonstration board
functions as a front panel solution for the HR21
set-top box (STB), and is designed to allow
testing of the versatile LED controller/driver
STLED316S.
STEVAL-CBP005V1
Data Brief
STEVAL-CBP005V1
The HR21 main board serves as the host
(master), and the STEVAL-CBP005V1
demonstration board functions as a slave. The
interface is an 11-pin connector cable, which
provides all required device control signals, the
3.3 and 5 V supply, the reset and IR sensor data
lines, and ground. The board also provides all
necessary function switches as well as LEDs for
function/status indication.
The STEVAL-CBP005V1 demonstration board
must be connected to the host to function
properly. Factory testing was completed using a
test jig, which emulated the host.
