measure_frequency PROTOTYPE integer measure_frequency(void) DESCRIPTION Measure the frequency of the square waveform at the CNTR input. Returns the frequency in Hz. The function is very accurate for values up to 100KHz. EXAMPLE f = p.measure_frequency() adc_freq PROTOTYPE integer adc_freq(integer chan) DESCRIPTION Measure the time period of a signal applied on one of the ADC channels. Returns period in microseconds. pulse_out PROTOTYPE integer pulse_out(integer delay_us) DESCRIPTION Send one pulse out on digital output pin D3 with high time equal to delay_us EXAMPLE p.pulse_out(1000) # generate 1ms pulse 104
