Getting started with STEVAL385LEDPSR demonstration board

First power-on procedure

The following section describes a step-by-step procedure which guarantees a correct

power-on during the first configuration of the board.

This guide assumes that the STEVAL385LEDPSR demonstration board is tested using the

following elements:

•

A DALI master or a 0 - 10 V master line or the serial line.

•

A USB TTL serial cable shipped with the board

•

An AC Power supply or a DC power supply

•

A computer running Microsoft® Windows®, Linux® or Apple® Mac OS® operating

system and HyperTerminal or an equivalent terminal program.

•

LED strings

Before first power-on the user shall connect the serial line as per the following instructions:

Connect the USB TTL serial cable to the USB port of the computer. Windows

recognizes the cable as a new COM port and launches the driver installation.

Install the appropriate USB TTL serial cable drivers. The drivers are the “virtual COM

port (VCP)” and they are provided by FTDI (http://www.ftdichip.com). If you need any

help to install the drivers, please refer to your IT administrator. Once the drivers are

installed, the Windows device manager panel shows a new USB serial port (COMx)

device and the COM number associated.

Run Hyperterminal or an equivalent program from the computer connected to the COM

port associated to the USB TTL serial cable. The serial connection configuration is:

•

Baud rate 115200

•

Data bits: 8

•

Stop bits: 1

•

Parity: no

•

Flow control: no handshake
