2.1 Package
contents
The STLED325 front panel demonstration board package includes:
●
Demonstration board (STEVAL-ILL029V1)
●
User manual (UM0943)
●
Schematic
●
Gerber files
2.2 System
requirements
The system operates in standalone mode by powering externally through an external
adaptor (9 V-18 V, 500 mA). The board can also be powered up using a laptop adaptor.
2.3
Powering on the system
As soon as the DC power supply is plugged in, the system is up and running. The
PWR/STBY LED (D4) is green with the MUTE LED (D3) turned off.
2.4 Startup
display
sequence/default setting of the system
On startup the system displays a rotating text welcome message “STLED325” on the 7-
segment display. Then, “c h b r” is displayed for about 2 seconds, after which the system
displays the channel number and brightness level information. When the board is powered
on for the first time, the following default settings are programmed:
●
Channel number: 00
●
Brightness information: 01 (01/16)
Subsequently, every time the board is powered on, it retains the last configured data and
displays the same on startup. The STM8S207K6 internal EEPROM is used to store the user
data (channel number and brightness information), and this feature is not available if an
external host is used.
