@brief DAC cosine channel configurations

Fields

chan_id: dac_channel_t

< The cosine wave channel id

freq_hz: u32

< The frequency of cosine wave, unit: Hz. The cosine wave generator is driven by RTC_FAST clock which is divide from RC_FAST, With the default RTC clock, the minimum frequency of cosine wave is about 130 Hz, Although it can support up to several MHz frequency theoretically, the waveform will distort at high frequency due to the hardware limitation. Typically not suggest to set the frequency higher than 200 KHz

clk_src: dac_cosine_clk_src_t

< The clock source of the cosine wave generator, currently only support DAC_COSINE_CLK_SRC_DEFAULT

atten: dac_cosine_atten_t

< The attenuation of cosine wave amplitude

phase: dac_cosine_phase_t

< The phase of cosine wave, can only support DAC_COSINE_PHASE_0 or DAC_COSINE_PHASE_180, default as 0 while setting an unsupported phase

offset: i8

< The DC offset of cosine wave

flags: dac_cosine_config_t__bindgen_ty_1

< Flags of cosine mode
