Adafruit RP2040 Prop-Maker Feather with I2S Audio Amplifier Product ID: 5768 The Adafruit Feather series gives you lots of options for a small, portable, rechargeable microcontroller board. By picking a feather and stacking on a FeatherWing you can create advanced projects quickly. One popular comb...
BREAKING: "i2s.h" removed, I2S library added (#8108) Core Make String reallocation warning more descriptive (#8131) Normalize core header's include guard. (#8110) makeword: sync header and implementation (#8097) Use optimal bundled library names (#8088) (#8098) Added IRAM_ATTR to _stop...

The issue is that it appears when i2s is running you no longer have access to i2c bus: [D] I2SESP32V1.h : 255 - startChannels - started Debug: es8388_get_voice_volume Debug: i2c_bus_read_bytes: addr=16 reglen=1 datalen=1 - reg=46 ...

oscilloscope, but there’s no reason the more powerful ESP32-series microcontroller could not be used for the same purpose, and Bojan’s Esp32_oscilloscope project does just that and works with ESP32, ESP32-S2, ESP32-S3 and ESP32-C3 boards using the I2S interface for fast data sampling....
