This sample program describes how to build a power supply monitoring system using the SNOOZE mode sequencer.

This sample program shows how to use the SNOOZE mode sequencer to detect fires. While the CPU operating clock is stopped, it is possible to control the sensor required for fire detection, measure the sensor output, and judge the measurement result, therefore this can achieve lower power consumption than before.

This sample program dynamically controls the display of a four-digit 7-segment LED indicator by using the SNOOZE mode sequencer (SMS). In this sample program, a cathode-common 7-segment LED indicator is used.

In this sample program, the SNOOZE mode sequencer and the 32-bit interval timer controls the LED brightness. By controlling the PWM output required for LED control with the SNOOZE mode sequencer, lower power consumption can be achieved than with CPU control.

Using the 32-bit interval timer, this sample program reverses LED indications based on the settings of the compare match detection flags when a timer interrupt occurs. The application also changes the timer interrupt generation intervals based on the number of times the switch has been previously pressed.

This sample program converts an analog voltage to a digital voltage with the RL78/G22's A/D converter (supporting software trigger and sequential conversion modes).

This solution is a reference design that detects human presence/absence using an infrared sensor, and turns on/off a LED automatically.

This solution is a reference design for a monitor that measures and detects the concentration of atmospheric particulate matter (PM) less than 2.5 micrometers in diameter in real-time.

This sample program uses the interval timer function of the timer array unit (TAU) of RL78/G14 and inverts the LED indication each time a timer interrupt occurs. Also, it changes the timer interrupt cycle time based on the number of times the switch is pressed.

This sample program controls dynamically lighting of 7-segment LEDs (cathode-common) using a program written in an Arduino language using the RL78/G14 Fast Prototyping Board (FPB).
