signal into digital values and applying conversion result upper / lower limit check function of ADC
(PWM diagnostic function). In case the measured current is either too high or too low, a fault is
assumed and in turn the PWM of the corresponding LED is switched OFF. By switching to Mode
2 the PWM output and diagnostic is started again.
If Ethernet is available (RH850/F1H and RH850/F1KM-S4 only) the corresponding Webserver
Handler is called periodically.
A short push on pushbutton S1 will switch to mode 2, holding it pressed for 3s or more will switch
to DeepSTOP mode.
After 30s without user action, the microcontroller will enter DeepSTOP mode on its own.
Mode 1 is called in a 1ms cycle using the Operating System Timer.
6.3 Mode 2
LED1 and LED2 blink alternately and the LEDs of the Blue LED Circle run around the Rotary
Encoder in a specific frequency. The frequency is determined by the analogue value of POT1
which is converted to a corresponding Timer Array Unit J interval time. After each interval, the
duty cycle of the LEDs LED1 and LED2 is adjusted to generate the alternatively blinking pattern,
as well as the positions of the Blue LED Circle. The number of blue LEDs which are circling can
be increased/decreased by the Rotary Encoder ENC1.
The load current through each of the RGB LEDs is evaluated by converting feedback/sense
signal into digital values and applying conversion result upper / lower limit check function of ADC
(PWM diagnostic function). In case the measured current is either too high or too low, a fault is
assumed and in turn the PWM of the corresponding LED is switched OFF. By switching to Mode
1 the PWM output and diagnostic is started again.
If Ethernet is available (RH850/F1H and RH850/F1KM-S4 only) the corresponding Webserver
Handler is called periodically.
A short push on pushbutton S1 will switch to mode 1, holding it pressed for 3s or more will switch
to DeepSTOP mode.
