Atomic Audio Base with M5ATOMS3R
-
I can't get this base to work with the AtomS3R . The example on the website doesn't work due to an i2s conflict between new and legacy i2s drivers. I finally got the following program to run meaning I see the text on the display however I can't seem to hear anything. Not sure if it isn't recording or not playing back properly. Does anyone have recent working code for this pair? Thanks.
#include "M5Unified.h" // Define buffer size (200KB for ESP32-S3) #define RECORD_SIZE (1024 * 200) static uint8_t *buffer = nullptr; void setup() { auto cfg = M5.config(); // Enable external I2C for ES8311 codec on the audio base cfg.external_imu = true; M5.begin(cfg); M5.Display.setFont(&fonts::FreeMonoBold9pt7b); Serial.begin(115200); // -------------------------- // Speaker Configuration (I2S Output) // AtomS3R I2S pins: BCK=8, WS=6, DOUT=5 // -------------------------- auto spk_cfg = M5.Speaker.config(); spk_cfg.pin_data_out = 5; spk_cfg.pin_bck = 8; spk_cfg.pin_ws = 6; spk_cfg.sample_rate = 44100; spk_cfg.i2s_port = I2S_NUM_0; spk_cfg.stereo = false; // Use mono for the base speaker M5.Speaker.config(spk_cfg); M5.Speaker.begin(); // -------------------------- // Microphone Configuration (I2S Input) // AtomS3R I2S pins: BCK=8, WS=6, DIN=7 // -------------------------- auto mic_cfg = M5.Mic.config(); mic_cfg.pin_data_in = 7; mic_cfg.pin_bck = 8; mic_cfg.pin_ws = 6; mic_cfg.sample_rate = 44100; mic_cfg.i2s_port = I2S_NUM_1; // Use separate I2S port for input M5.Mic.config(mic_cfg); M5.Mic.begin(); // Set volume/gain M5.Speaker.setVolume(50); // For v0.2.14, set mic gain via config if needed (default works for most cases) // mic_cfg.magnification = 2; // Allocate recording buffer buffer = (uint8_t *)malloc(RECORD_SIZE); if (buffer == nullptr) { Serial.println("Memory allocation failed!"); while (true) delay(1000); } Serial.println("Device ready! Press button to record/play"); M5.Display.println("Click to\nRecord & Play"); } void loop() { M5.update(); if (M5.BtnA.wasClicked()) { M5.Display.fillScreen(BLACK); M5.Display.setCursor(0, 0); // -------------------------- // Recording // -------------------------- M5.Display.println("Recording..."); Serial.println("Start recording"); M5.Mic.record(buffer, RECORD_SIZE, 44100); delay(3000); // -------------------------- // Playback // -------------------------- M5.Display.println("Playing..."); Serial.println("Start playing"); M5.Speaker.playRaw(buffer, RECORD_SIZE, 44100, false, 1); while (M5.Speaker.isPlaying()) delay(10); M5.Display.println("Done"); Serial.println("Done"); } } -
The AtomS3R and Atomic Audio Base will work using the RecordPlay example in https://github.com/m5stack/M5Atomic-EchoBase/tree/main/example . Whenever I try to include both M5Unified.h and M5EchoBase in the same sketch I get the i2s conflict between new and legacy i2s drivers . I cant get any sound however when using just the M5Unified.h library. Below is my latest code. Still no sound?
