Frequency Discipline Sample
Samples demonstrate how to write code using certain features. They are not performance benchmarks. The output examples
shown here are for illustration only. Your output may vary.
Frequency discipline is a Time-Aware GPIO (TGPIO) use case that combines the TGPIO hardware capability with software to generate a signal as close to the required frequency as possible (with the smallest period and phase errors) by changing the TGPIO period repeatedly. The frequency discipline sample (tcc_frequency_discipline_sample) demonstrates this use case.
