4.3.4 Serial Command mode

In this mode, the LEDs are dimmed by using commands depending on the type of communication.

Specify the communication format, communication command type, and channels to use for serial communication.

To use this mode, a host controller for serial communication must be connected to the serial communication port of the

evaluation board. For details, refer to the user’s manuals of the microcontroller and evaluation board.

For the command of Serial Command mode, refer to APPENDIX B SERIAL COMMAND MODE COMMUNICATION

COMMANDS.

<1> Select the [Serial Command] button in Dimmer Program and specify from the [by] and [type] drop-down lists the

communication mode and communication command system to be used, respectively.

 [by]

Select from UART6

Note 1

, UART0, SPI, and IIC.

UART6 Serial communication is performed in this mode by using UART (universal asynchronous

receiver transmitter) with the TxD6 or RxD6 pin of the device.

UART1 Serial communication is performed in this mode by using UART (universal asynchronous

receiver transmitter) with the TxD1 or RxD1 pin of the device.

UART0 Serial communication is performed in this mode by using UART with the TxD0 or RxD0

pin of the device.

SPI 3-wire serial communication is performed in this mode by using the SI1n, SO1n, or SCK1n

pin of the device. The following pins can be used as enabling pins when using the device

of the evaluation board as the slave. (For details, see the [CSI Property] dialog box

described in CHAPTER 5 WINDOW REFERENCE.)

 The INTP0, INTP2, or INTP3 pin: EV-K0-HCD, EV-K0-HCD2, and EZ-0009

 The SSI11 pin: EZ-0005 and EZ-0006

Remark n = 0: EV-K0-HCD, EV-K0-HCD2, and EZ-0009

n = 1: EZ-0005 and EZ-0006

IIC Serial communication is performed in this mode via the I

C (inter-integrated circuit) bus by

using the SCLn and SDAn pins of the device.

Remark n = 0: EV-K0-HCD, EV-K0-HCD2, and EZ-0009

n = A0: EZ-0005 and EZ-0006
