Uczenie dodatkowej frazy wybudzaj\u0105cej<\/h2>\n\n\n\n

Aby nauczy\u0107 modu\u0142 nowej frazy wybudzaj\u0105cej (zawsze aktywne pozostaje “Hello Robot!<\/strong>“) nale\u017cy po wywo\u0142aniu standardowym wyg\u0142osi\u0107 fraz\u0119: Learning wake word<\/strong>“. Nast\u0119pnie poda\u0107 nowe sformu\u0142owanie wybudzaj\u0105ce. Ja poda\u0142em Hello Jane. <\/strong>Trzeba to zrobi\u0107 trzykrotnie s\u0142uchaj\u0105c polece\u0144.<\/p>\n\n\n\n

Biblioteka MicroPython<\/h2>\n\n\n\n

Biblioteka lekko zmodyfikowana. W oryginalnej by\u0142 b\u0142\u0105d w metodzie get_cmdid()<\/strong>. Poprawiony przez Chat GPT<\/strong><\/em>.
Uwaga! Kody nie dzia\u0142aj\u0105 dla ESP8266. Prawdopodobnie problem tkwi w bibliotece I2C. Mo\u017ce trzeba u\u017cy\u0107 softI2C? Sprawdz\u0119.
Wszystko dobrze dzia\u0142a na ESP32.<\/p>\n\n\n
