I2C Multiplexer SMD A0/A1/A2 pins for base address 0x70

Customer:

I’m unable to access the forum with my credentials, so I can’t get the technical support I need. I have a technical question: do the A0, A1, and A2 pins on the I2C Multiplexer SMD need to be tied to ground if I want to use only the base address (0x70), or is this already done?

Ne mogu se ulogirati/prijaviti na forum sa podacima korisničkog računa e-radionice (kako se traži) pa prema tome ne mogu dobiti ni tehničku podršku koja mi treba.

Molim da mi hitno odgovorite na slijedeće tehničko pitanje (jer na forum ne mogu iz nekog razloga sa mailom/passwordom od e-radionice) :

Je li potrebno na I2C multiplexeru SMD pinove A0, A1 i A2 staviti na masu ako želim samo osnovnu adresu (0x70), ili je to već učinjeno ?

This is already done. To be sure, you can use an I2C scanner to find the I2C addresses of connected devices: Arduino Playground - I2cScanner

isprike što ne možete pristupiti forumu.

To je već učinjeno, no da biste bili sigurni, možete koristiti I2C scanner da pronađete I2C adresu uređaja koje su spojene: Arduino Playground - I2cScanner
