I2C Communication

Question asked by Alan Calonico on Dec 6, 2013

Dear all,

I'm working with 2u (MC9S08SH8CWJ and MC9S08QG4) the problem is that the slave doesn't respond anything, as the protocol indicate first I send a byte(with an specific add 0x84) and then read a byte saved in a void byte in master mode,  and in slave mode i'm just send a data with an pointer that point an specif address with content.

 

I'm using the I2C methods and function, but doesn't work, I see an Oscilloscope like the Master send the start conditional, slave address, and the  write bit, but like never receive the acknowledge, so i think that problem is slave rigth? have you any idea like repair?
