//MODIFIED Version of Adafruit Trinket code to give attiny85 PCM capability
//The Attiny will take a very short sound sample that will sound good if looped
//I used the sound of a sonic screwdriver to example this capability
//Crete PCM using a program such as http://thieumsweb.free.fr/english/gbacss.html, copy the code right after PROGMEM = {    and make sure that it ends with the };
//I use 8000 as my sample rate as allows the longest soundbyte to be uploaded to the chip
/*
if you change the sample rate, alter the sample_rate value
Otherwise the program will create a looped sound on pin 4 of the attiny85
*/
// Audio playback sketch for Adafruit Trinket.  Requires 3.3V
// Trinket board and Winbond W25Q80BV serial flash loaded with
// audio data.  PWM output on pin 4; add ~25 KHz low-pass filter
// prior to amplification.  Uses ATtiny-specific registers;
// WILL NOT RUN ON OTHER ARDUINOS.

В первом случае он играет при подаче питания или после ресета. Для прямого подключения динамика синхронно задействованы 2 PWMа.

Во втором случае играет на один PWM но по непрерывно по кругу.

Нужно:

Добавить в код кнопку при нажатии которой один из выходов будет вставать в режим HIGH, после отпускания которой будет запускаться проигрывание сэмпла, после проигрывания сэмпла выход находящийся в режиме HIGH должен вставать в LOW.

Так же проигрывание должно осуществляться не двумя а одним PWMом, т.к. будет использоваться LPF и УНЧ.

Какой код будет взят за основу не важно, первый выглядит понятнее, второй полнее (и может быть лучше). В идеале перепилить оба.
