The datasheet of the slave device is in the attachment. I realized that communication with the K60 without problem after each conversation i have to wait 1,3µs. The deviceaddress is 0x48 after that i have to send the subaddress 0x01 for the Configurationregister and the data 0b01111001 for the device. But you already mentioned it, the k28 only send the deviceaddress without subaddress and data . Do you know what i did wrong?</P><PRE class="" data-fulltext="" data-placeholder="Übersetzung" dir="ltr" style="text-align: left; height: 72px;"><SPAN lang="en">&nbsp;</SPAN></PRE></BODY></HTML> Wed, 05 Dec 2018 11:46:05 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/I2C-with-MCUexpresso-and-FRDMK28/m-p/827578#M50018 philippadolph 2018-12-05T11:46:05Z https://community.nxp.com/t5/Kinetis-Microcontrollers/I2C-with-MCUexpresso-and-FRDMK28/m-p/827579#M50019 <HTML><HEAD></HEAD><BODY><P>I found my problem, ty for your help</P></BODY></HTML> Thu, 06 Dec 2018 12:08:03 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/I2C-with-MCUexpresso-and-FRDMK28/m-p/827579#M50019 philippadolph 2018-12-06T12:08:03Z
