Summary

Declaration

from dac_ll.h:125

static inline void dac_ll_cw_set_freq(uint32_t freq, uint32_t rtc8m_freq);

Arguments

Argument

Description

freq

rtc8m_freq

the calibrated RTC 8M clock frequency

Notes

We know that CLK8M is about 8M, but don't know the actual value. so this freq have limited error.
