    Hello ,

    There is no I2C HW on SPC56ELx.

    I recommend to switch on an other family (B or BC or D)

    or to develop your own I2C SW.

    example below :

    Hello,

    if you download SPC5Studio and look at Chorus family drivers you will find a bit-bang implementation of I2C driver.

    Files to look at are called i2c_sw.c/i2c_sw.h
