As I presented in the previous log, I2C supporting in ATtiny10 seems to be successful. This time I activate A/D converter of ATtiny10. Indeed, ATtiny10 supporting I2C LCD and A/D leads to super simple Voltage meter!!

All you will need is ATtiny10 and I2C LCD. Nothing more. I made a assembly code, which contains lots of redundancy and non-nessesity part such as welcome message "Hello ATtiny10", and also voltage display part is NOT optimised yet but

it can be still inside internal flash of ATtiny10.My dirty assembly code is released on github and actual operation can be found in the following movie. Indeed response is well acceptable for voltage measurement application (main concern is accuracy, though...) Anyway, have fun!
