For example, you calibration our ADC module by a external standard power supply. Then you can transfer data to register ADCx_OFS after you compare testing result and expected result.</P><P></P><P>Best Regards</P><P>Paul</P></BODY></HTML> Mon, 18 Aug 2014 07:31:56 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Kinetis-L-ADC-Offset-Correction/m-p/360742#M18303 Paul_Tian 2014-08-18T07:31:56Z
