I downloaded the K64 sample code for tower board (Kinetis_K64_SC_INIT) from the web site and just changed the slave address to 0x00. And I just pulled up the I2C1 line, PTC10 and PTC11. There is no I2C device. However I saw some "Ack"s (Please refer the attached picture)... Is it normal? or any register setting would be wrong?? I added ODE=1 code into the sample code but there is no change..
I'm using a FRDM-K64F(revB, sch revD1), not tower board. But I thought the sample code would work on FRDM-K64F as well...
