I am using an ATtiny841 microcontroller as an I2C slave, but I have difficulty finding information on it. So for, all I have are application notes and reference code for TWI and USI module.
It seems like ATtiny841 has a unique TWI slave interface, which is slightly different. Although I could write out the code manually it would really help if there is a standard sample code that I can refer to.
Thanks in advance.
