6.4 StandBy
Entering standby mode will turn off all unnecessary functions and switch the controller into
DeepSTOP for low power consumption. This is indicated by a 2s interval of LED2 generated by
the Timer Array Unit J.
A wake-up can be performed by a short push the pushbutton S1, the Rotary Encoder
Pushbutton , changing the configuration of the DIP switch S3 or turning potentiometer POT1
more than 25% of the actual state. DIP switch and POT1 related wake-up events are generated
by using the Low Power Sampler triggered by Timer Array Unit J in a 500ms interval. Performing
a wake-up will resume the last mode the SW was in before standby was entered.
6.5 Webserver Application
On StarterKits with available Ethernet (RH850/F1H and RH850/F1KM-S4 only) the open source
TCP/IP Stack lwIP is implemented to provide webserver functionality. The website can be
accessed via the IP address 192.168.0.2. In Mode 1 and Mode 2 certain runtime information such
as CPU load, received/transmitted frames, potentiometer value, RGB color and test results are
present on the website. The data is transferred to the website via SSI, the corresponding XML
document can be accessed via 192.168.0.2/status.ssi.
Furthermore the Mode of the StarterKit (Mode 1, Mode 2, StandBy) as well as the RGB LED color
can be controlled via CGI using buttons and a color picker implemented on the website.
