DIP switch/external interface connector

The board consists of an 8-position DIP switch (SW2). All the switches should be in the ON
position (towards circle/ON side) for the demo to work. When the device STLED325 is
required to be isolated from the onboard STM8S207K6 host and controlled through an
2
external I C host, all the switches should be moved to the OFF position. Then, the
STLED325 control pins can be accessed through the external interface connector (J3). A
detailed description of the external interface connector is provided on the bottom silkscreen
of the board and also listed below for reference.
Figure 7.

IR sensor connector

A 38 kHz IR sensor is mounted at J4 for IR control and supports RC5 protocol.

Interrupt LED

There is a blue interrupt LED (D21 : INTR) which blinks whenever an interrupt is asserted
from the device which may be due to a front panel key press, remote control key press, RTC
alarm, wake-up from standby, etc.
