Fantastic, it works!
Don't know why I wasn't able to find it first.
Just setup my first M5 echo! The product seems great so far, I tried the factory BT firmware and it works fine.
I want to test the Recoder&Replay example, but an error occurred after pressing the button:
Init i2s_set_pin E (2137) I2S: i2s_check_set_mclk(253): ESP32 only support to set GPIO0/GPIO1/GPIO3 as mclk signal, error GPIO number:2133 E (2142) I2S: i2s_set_pin(314): mclk config failed
err += i2s_set_pin(SPEAKER_I2S_NUMBER, &tx_pin_config);
#define SPEAKER_I2S_NUMBER I2S_NUM_0
I searched for some solution but I didn't find a good solution.
Using Visual Studio code, this is the platformio.ini
[env:esp32dev] platform = espressif32 board = esp32dev framework = arduino monitor_speed = 115200 upload_speed = 115200 lib_deps = m5stack/M5Atom @ ^0.0.9 fastled/FastLED @ ^3.5.0
Thanks in advance!
