ESP32 (wroom 32) is a highly integrated Dual Core MCU with WiFi and Bluetooth/ BLE 4. ということでmbedから波形を出力してみました mbedのp18は10bitのDACが接続されており、任意の電圧を出力することができます 波形はSIN関数を使うことでテーブルを持つ必要はありません 今回はテストに使うだけなので波形を出力する機能しかありません. ARM mbed is a platform and operating system based on 32-bit ARM Cortex-M microcontrollers. We decided to revisit it this week and spin up a new version with the WM8960 which makes it a lot easier to fabricate, and also less expensive since it has analog inputs instead of requiring separate I2S microphones.
