user76262: I'm working on a project using TTGO TS wich communicate wih arduino via I²C protocole
How can I find the adress of TTGO TS board used in I²C communication ?

user4143: The TTGO TS uses an ST7735 display. This is not an I2C device. Instead it uses its own custom serial protocol. Since the DC pin is broken out for you it uses the 4-wire serial interface which is simplest to use with SPI.
It's confusing that they use the terms SCL and SDA, which makes you think it's I2C, but it's not.
