I have searched with out great success and again need guidance, probably the phrase or correct words.
is there any preferred articles regarding AT90can128(or atmega)communication to an Arduino uno based chip using the I2C?
I am using peter Fleury's TWI lib and the Arduino wire lib but there seems to be a miss match. im not sure but think it is to do with the addressing 7 or 8 bit addresses.
the AT90 seems to output the correct wave form on the bus but the Arduino is not responding.
Pull ups fitted I presume correct speed at 90k (11.22 us)
is I mentioned ive tried all sorts of Google phrases but don't seem to be able to find the correct answer.
any pointers are welcome.
I can get two Arduinos talking master slave no problem.
