AVR®: Using Hardware Fast PWM Mode and Testing with Data Visualizer
In this video: Understand the Fast PWM timing diagram. Modify the PWM initialization function to configure 11-bit PWM and clear Output Compare 1B (OC1B) on compare match. Find that OC1B is an alternate pin function of PB2 and setting this as an output. Use the Data Visualizer's GPIO view in pin mode to analyze the output waveforms. Utilize cursors to measure the frequency of the waveforms of both the LED pin (PB5) and OC1B (PB2). Check the measured frequency (7813 Hz) against the formula in the datasheet (7812 Hz), showing the frequency is measured as expected.
