as a project i tried to hook up an I2C Device to my esp8266.
We (accidently) ordered the ESP-01 Version where only 2 GPIO pins are available.

Enough i thought, but i tried to hook up my I2C device with
sda=0 -- connect to pin GPIO0
scl=2 -- connect to pin GPIO2
print(i2c.setup(id, sda, scl, i2c.SLOW))
and it sais "no i2c for D0"
am i missing something? is there a way to use the tx pin for i2c communication?
