From the project
AquesTalk pico LSI into the Grove of M5
DIP: Dual In-line Package I2C: Inte-Integrated Circuit UART: Universal Asynchronous Receiver Transmitter SPI: Serial Peripheral Interface
※ AquesTalk pico LSIは付属しません。 ※ スピーカー、スピーカーケーブルは付属しません。 ※ ケースや足などは付属しません。
※ 1, 2, 3, 4, 5は、DIPスイッチの番号です。DIPスイッチはONでGND接続のため、ON=0, OFF=1です。 (1) ATP3011の場合、SLEEP解除後の'?'送信で自動設定します。ATP3012の場合EEPROMに設定します。 (2) 音声再生の前後にノイズが発生します。
- UARTスピードを設定（ATP3011が対象。UARTのみ。デフォルト: 実行しない） AquesTalk pico LSI (ATP3011) のUARTスピードを設定します。GPIO5がAquesTalk pico LSIのSLEEPピンと接続している必要があります。
