Issue with kit.write() in ESP32 AudioKit Code
Valdeci Ribeiro
Hello everyone,
I am working on the following code example for the ESP32 that demonstrates headphone detection and sine wave generation. The code uses the AudioKitHAL and SineWaveGenerator libraries:
/**

#include "AudioKitHAL.h"
#include "SineWaveGenerator.h"
AudioKit kit;
SineWaveGenerator wave;
const int BUFFER_SIZE = 1024;
uint8_t buffer[BUFFER_SIZE];
void setup() {
LOGLEVEL_AUDIOKIT = AudioKitInfo;
Serial.begin(115200);
// open in write mode
auto cfg = kit.defaultConfig(KitOutput);
kit.begin(cfg);
// 1000 Hz
wave.setFrequency(1000);
wave.setSampleRate(cfg.sampleRate());
}
void loop() {
size_t l = wave.read(buffer, BUFFER_SIZE);
kit.write(buffer, l); // Issue occurs here
}
However, I am encountering a compiler error that states:
'class audiokit::AudioKit' has no member named 'write'
I am not sure if this is due to a change in the AudioKitHAL library, a missing dependency, or if the example code itself has become outdated.
- Does anyone know if the kit.write() function has been deprecated or replaced?
- Is there an alternative way to send audio data to the output using the current AudioKitHAL version?
Any guidance or suggestions would be greatly appreciated.
Thank you in advance!
