The current library needs two fixes solving the deprecated ``i2s_write_bytes`` function.
In file AudioOutputI2S.cpp:
bool AudioOutputI2S::ConsumeSample(int16_t sample[2])
{
//return if we haven't called ::begin yet
if (!i2sOn)
return false;
int16_t ms[2];
ms[0] = sample[0];
ms[1] = sample[1];
MakeSampleStereo16( ms );
if (this->mono) {
// Average the two samples and overwrite
int32_t ttl = ms[LEFTCHANNEL] + ms[RIGHTCHANNEL];
ms[LEFTCHANNEL] = ms[RIGHTCHANNEL] = (ttl>>1) & 0xffff;
}
#ifdef ESP32
uint32_t s32;
if (output_mode == INTERNAL_DAC)
{
int16_t l = Amplify(ms[LEFTCHANNEL]) + 0x8000;
int16_t r = Amplify(ms[RIGHTCHANNEL]) + 0x8000;
s32 = (r << 16) | (l & 0xffff);
}
else
{
s32 = ((Amplify(ms[RIGHTCHANNEL])) << 16) | (Amplify(ms[LEFTCHANNEL]) & 0xffff);
}
// Deprecated. Use i2s_write
// return i2s_write_bytes((i2s_port_t)portNo, (const char *)&s32, sizeof(uint32_t), 0);
size_t bytes_written;
i2s_write((i2s_port_t)portNo, (const char*)&s32, sizeof(uint32_t), &bytes_written, 0);
return bytes_written;
#elif defined(ESP8266)
uint32_t s32 = ((Amplify(ms[RIGHTCHANNEL])) << 16) | (Amplify(ms[LEFTCHANNEL]) & 0xffff);
return i2s_write_sample_nb(s32); // If we can't store it, return false. OTW true
#elif defined(ARDUINO_ARCH_RP2040)
return !!I2S.write((void*)ms, 4);
#endif
}
In file AudioOutputI2SNoDac.cpp:
bool AudioOutputI2SNoDAC::ConsumeSample(int16_t sample[2])
{
int16_t ms[2];
ms[0] = sample[0];
ms[1] = sample[1];
MakeSampleStereo16( ms );
// Make delta-sigma filled buffer
uint32_t dsBuff[8];
DeltaSigma(ms, dsBuff);
// Either send complete pulse stream or nothing
#ifdef ESP32
// Deprecated. Use i2s_write
// if (!i2s_write_bytes((i2s_port_t)portNo, (const char *)dsBuff, sizeof(uint32_t) * (oversample/32), 0))
size_t bytes_written;
i2s_write((i2s_port_t)portNo, (const char *)dsBuff, sizeof(uint32_t) * (oversample/32), &bytes_written, 0);
if (!bytes_written)
return false;
#elif defined(ESP8266)
if (!i2s_write_sample_nb(dsBuff[0])) return false; // No room at the inn
// At this point we've sent in first of possibly 8 32-bits, need to send
// remaining ones even if they block.
for (int i = 32; i < oversample; i+=32)
i2s_write_sample( dsBuff[i / 32]);
#elif defined(ARDUINO_ARCH_RP2040)
int16_t *p = (int16_t *) dsBuff;
for (int i = 0; i < oversample / 16; i++) {
I2S.write(*(p++));
}
#endif
return true;
