RL78/I1A
Chapter 8 Applilet EZ for HCD Controller
Make sure that SW2 dip switch of the
RL78/I1A DC/DC LED Control Evaluation
Board
is in flash programming mode, and that the USB and power supply cables
are connected correctly. Click the
“Save”
button and then the
“All P.”
button.
After downloading the application, please disconnect the USB and power supply
cables and set the board to the normal operation mode.

Plug again the DC 5V power supply, and you should now be able to control the
LEDs on the
RL78/I1A DC/DC LED Control Evaluation Board
via the IR remote
control protocol by using an IR transmitter device. For example, Renesas
Electronics offers the
Lighting Communication Master Evaluation Board
(EZ-
0008). This board can be used as a communication master device supporting
DMX512, DALI and IR communications.

System Configuration for IR Remote Control
Figure 39:
On the
Lighting Communication Master Evaluation Board
, please confirm that
SW4 is set to “RUN“ and SW1 to the expected channel (the channel should be
the same as the one set in Applilet EZ for HCD).
<6>
The output code is based on NEC IR remote control protocol:
CH1: Send custom code data code 0x5AA5
CH2: Send custom code data code 0xDA25
Place the IR transmitter (LED1) of the
Lighting Communication Master Evaluation
Board
in the line-of-sight of the IR receiver (U2) of the
RL78/I1A DC/DC LED
Control Evaluation Board
.
<7>
Connect the
Lighting Communication Master Evaluation Board
to the host PC
using a USB cable.
<8>
Plug the DC 5V power supply cable to the
RL78/I1A DC/DC LED Control
Evaluation Board
via connector CN1.
<9>
Press switch SW2 of the
Lighting Communication Master Evaluation Board
to
send IR signals to the
RL78/I1A DC/DC LED Control Evaluation Board
.
