ADC-PWM Synchronization Using ADC Interrupt

Use the ADC block to sample an analog voltage and use the PWM block to generate a pulse waveform. This example also shows how to use the Hardware Interrupt block to synchronize the change in the PWM duty cycle with analog to digital conversion of voltage. In the generated code, changes in the voltage of the ADC input alter the duty cycle of the PWM output. The period of the PWM waveform remains constant.
