Multiple Pzems

[efakostya]

Hello friends, tell me how to fix the library to read in a loop. I don't like the case option. PZEM004T pzem1 (D1, D2); PZEM004T pzem2 (D3, D4); PZEM004T pzem3 (D5, D6);

v [0] = pzem1.voltage (); c [0] = pzem1.current (); p [0] = pzem1.power (); e [0] = pzem1.energy (); f [0] = pzem1.frequency ();

v [1] = pzem2.voltage (); c [1] = pzem2.current (); p [1] = pzem2.power (); e [1] = pzem2.energy (); f [1] = pzem2.frequency ();

v [2] = pzem3.voltage (); c [2] = pzem3.current (); p [2] = pzem3.power (); e [2] = pzem3.energy (); f [2] = pzem3.frequency ();

Is it possible to somehow bring to the form: for (size_t i = 0; i < 3; i++){ v [i] = pzem[i].voltage (); c [i] = pzem[i].current (); p [i] = pzem[i].power (); e [i] = pzem[i].energy (); f [i] = pzem[i].frequency (); }

You can use an array of pointers

PZEM004T* pzem[] = {
  new PZEM004T(D1, D2),
  new PZEM004T(D3, D4),
  new PZEM004T(D5, D6)
};

for (size_t i = 0; i < 3; i++){
  v[i] = pzem[i]->voltage();
  ...
}

Thank you so much for the hint. Your library helped me a lot in creating the application.

Огромное спасибо Вам за подсказку. Ваша библиотека очень помогла мне в создании приложения.

Hello, can I take a look at your code? I can't seem to make mine work (2 of v2.0)
