STEVAL-CBP005V1
Front panel demonstration board based on the STLED316S
Features
■16 x 3 mm blue LEDs for status and function
indication
■2 x 5 mm BiColor LEDs
■12 front panel function keys
■1 reset button on rear
■Provision for mounting IR sensor and
associated bias components
■11-pin connector termination for easy interface
to host
■All data and power lines and additional signals
available on connector
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.
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.
