Re: TDA7719

Доброго здоровья! Возникла проблема с сохранением вводимых параметров управления TDA7719. Так при установке отрицательных значений входного аттенюатора по любому из входов данные значения не сохраняются в EEPROM, мало того при этом ряд других установок при включении питания могут принять произвольные значения. В чем может быть проблема?

Re: TDA7719

Надо заменить

EEPROM.update(20,vol0);EEPROM.update(21,vol1);EEPROM.update(22,vol2);EEPROM.update(23,vol3);EEPROM.update(24,vol4);

на

EEPROM.update(20,vol0+15);EEPROM.update(21,vol1+15);EEPROM.update(22,vol2+15);EEPROM.update(23,vol3+15);EEPROM.update(24,vol4+15);


далее

vol0=EEPROM.read(20);vol1=EEPROM.read(21);vol2=EEPROM.read(22);vol3=EEPROM.read(23);vol4=EEPROM.read(24);

заменить на

vol0=EEPROM.read(20)-15;vol1=EEPROM.read(21)-15;vol2=EEPROM.read(22)-15;vol3=EEPROM.read(23)-15;vol4=EEPROM.read(24)-15;

далее

после

lcd.setCursor(0,0);lcd.print("    TDA7719    ");delay(1000);

добавить

  switch(in){
     case 0: vol_att = vol0;break;
     case 1: vol_att = vol1;break;
     case 2: vol_att = vol2;break;
     case 5: vol_att = vol3;break;
     case 6: vol_att = vol4;break;
     }
