This demo is a simple blink. When switch SW1 is closed flux detect an event "power on" and start simplified code Sinusoidal Generator at pin 'GP28'.

This demo is a PWM controlled LED. When switch SW2 is closed flux detect an event "power on" and start simplified code Sinusoidal Generator at pin 'GP20'. But in this example, the PWM duty cycle will depend on resistance of R3. R3 will work as a voltage divider. So we demonstrate PWM output and ADC reading at the same time.

In this example, we demonstrating digital read and digital write features. When switch SW3 is closed flux detect an event "power on" and start a code that read voltage at pins 'GP3' and 'GP6'. If we have a 'high'(5 volts) logic level at pin 'GP3' (button B1 is pressed) then we generate a 'high'(5 volts) logic level at pin 'GP19'(LED3 is ON) If we have a 'high'(5 volts) logic level at pin 'GP6' (button B2 is pressed) then we generate a 'high'(5 volts) logic level at pin 'GP16'(LED3 is ON)
