6, Arduino IDE example program

Arduino UNO Graphical Example Program:

void send_data(int addr) {
  int i;
  digitalWrite(8, LOW);
  delay(3); //>2ms
  for (i = 0; i < 8; i++) {
    digitalWrite(8, HIGH);
    if (addr & 1) {
      delayMicroseconds(2400); //>2400us
      digitalWrite(8, LOW);
      delayMicroseconds(800);
    } //>800us
    else {
      delayMicroseconds(800); //>800us
      digitalWrite(8, LOW);
      delayMicroseconds(2400);
    } //>2400us
    addr >>= 1;
  }
  digitalWrite(8, HIGH);
}

void setup(){
  pinMode(8, OUTPUT);
}

void loop(){
  send_data(0x10); //volume control 0xE0-E7;
  delay(1000);
  send_data(0x11); //volume control 0xE0-E7;
  delay(1000);
  send_data(0x12); //volume control 0xE0-E7;
  delay(1000);
  send_data(0x13); //volume control 0xE0-E7;
  delay(1000);

}

ESP32 Python Example (for Mixly IDE / Micskit)
(Choose the Python ESP32 [ESP32 Generic(4MB)] to switch to code mode upload):

import machine
import time
def voice_broadcast(Pin, directives, delay):
    Pin.value(0)
    time.sleep_ms(5)
    for i in range(0, 8, 1):
        if ((directives>>i)&0x01) == 0:
            Pin.value(1)
            time.sleep_us(800)
            Pin.value(0)
            time.sleep_us(2400)
        elif ((directives>>i)&0x01) == 1:
            Pin.value(1)
            time.sleep_us(2400)
            Pin.value(0)
            time.sleep_us(800)
    Pin.value(1)
    time.sleep_ms(delay)

Pin4 = machine.Pin(4, machine.Pin.OUT)
Pin4.value(1)
time.sleep_ms(10)


voice_broadcast(Pin4, 0x10,1000)
voice_broadcast(Pin4, 0x11,1000)
voice_broadcast(Pin4, 0x12,1000)
voice_broadcast(Pin4, 0x13,1000)
