Figure 11. Alarm display
Demo mode
The system enters into demo mode by using the DEMO touchkey on the front panel. In this
mode, scrolling text with varying brightness and increasing scrolling speed is displayed
continuously on the display.
Text displayed: “STLED325-STMPE24M31 Front Panel Demo” followed by blinking of 325
two times (left aligned and right aligned).
The system comes out of demo mode and returns to channel-brightness display when either
any of the touchkeys or RC key is pressed, or RTC alarm condition is met.
Remote control operation
The system currently supports only RC5 protocol; however, it can be easily adapted to
implement other RC protocols. The MENU options support changing the currently used RC
protocol but are not currently implemented in the system. For more details, refer to the
STLED325 datasheet.
The following RC operations can be done using IR decoding feature of STLED325.
