Detailed Description

Macro Definition Documentation

◆ WS_SOUND_CH_CTRL_CH1_ENABLE

#define WS_SOUND_CH_CTRL_CH1_ENABLE 0x01

Enable sound channel 1.

Definition at line 932 of file ports.h.

◆ WS_SOUND_CH_CTRL_CH2_ENABLE

#define WS_SOUND_CH_CTRL_CH2_ENABLE 0x02

Enable sound channel 2.

Definition at line 936 of file ports.h.

◆ WS_SOUND_CH_CTRL_CH2_VOICE

#define WS_SOUND_CH_CTRL_CH2_VOICE 0x20

Enable sound channel 2 in voice mode. This overrides the channel 2 enable bit.

Definition at line 948 of file ports.h.

◆ WS_SOUND_CH_CTRL_CH3_ENABLE

#define WS_SOUND_CH_CTRL_CH3_ENABLE 0x04

Enable sound channel 3.

Definition at line 940 of file ports.h.

◆ WS_SOUND_CH_CTRL_CH3_SWEEP

#define WS_SOUND_CH_CTRL_CH3_SWEEP 0x40

Enable applying a frequency sweep effect on sound channel 3.

Definition at line 952 of file ports.h.

◆ WS_SOUND_CH_CTRL_CH4_ENABLE

#define WS_SOUND_CH_CTRL_CH4_ENABLE 0x08

Enable sound channel 4.

Definition at line 944 of file ports.h.

◆ WS_SOUND_CH_CTRL_CH4_NOISE

#define WS_SOUND_CH_CTRL_CH4_NOISE 0x80

Provide samples to sound channel 4 from the LFSR noise generator, as opposed to the wavetable.

Definition at line 956 of file ports.h.

◆ WS_SOUND_CH_CTRL_PORT

#define WS_SOUND_CH_CTRL_PORT 0x90

Controls sound channels.

Definition at line 928 of file ports.h.

◆ WS_SOUND_FREQ_CH1_PORT

#define WS_SOUND_FREQ_CH1_PORT 0x80

Sound channel 1 frequency, stored as a divisor. Every 2048 - divisor cycles, the index of the sample to be fetched from the wavetable is incremented.

The resulting frequency is calculated as follows: sample rate = 3072000 Hz / (2048 - divisor).

Note that this refers to the sample rate of each sample in the wavetable, and needs to be scaled accordingly for a given waveform. For example, a 50% duty square wave (16 samples of 0 followed by 16 samples of 15) will have an effective sample rate of (3072000 / 32) Hz / (2048 - divisor), or 96000 Hz / (2048 - divisor).
