Hi,

I am using ATTINY45 as an I2C master. I am running into undeclared errors on these which are related to the chip's UART I am assuming.

Code: Select all

UCSRA, UDRE, UDR, UCSRB,TXEN, UBBRL

I am using the latest usb to i2c tiny library from here:

I checked the Atmel file iotnx45.h but it doesn't contain these definitions of course. Should I get a newer file?
If so where would I get it. I am currently using Atmel Studio 6.1 (beta).

Thanks, keiichicom

The tiny45 doesn't have a UART You would either need to emulate one in software (not sure you can do that while trying to maintain USB timing) or comment out any use of it.

Thanks Mike, appreciated. I don't need the UART so I will just comment out those defines, so that the code compiles.
