Summary

Declaration

from sdm_ll.h:40

__attribute__((always_inline)) static inline void sdm_ll_set_pulse_density(gpio_sd_dev_t *hw, int channel, int8_t density);

Arguments

Argument

Declared as

Description

gpio_sd_dev_t *

Peripheral SIGMADELTA hardware instance address.

channel

int

Sigma-delta channel number

density

int8_t

Sigma-delta quantized density of one channel, the value ranges from -128 to 127, recommended range is -90 ~ 90. The waveform is more like a random one in this range.
