is there any hope for analog pin (a0) on esp8266 to use as sda/scl pin and/or with irq?
thank you,

use analog pin as digital?
Re: use analog pin as digital?
No. You can use the analog pin as an slow digital input, in case you are low on ressources, including setting up a multi-position switch. Each reading takes about 100 µs. But you have to poll it, there is no interrupt associated.
