    Damn indeed - we have the C0 revision here at our side. Since we own even not only some of them, is there any chance to still use that version via TWI?

    Hi Ole,

    sorry for digging this one out again. I was talking to some of your colleagues in Dresden while the nordic tech tour and they told me that there should be a chance to get hwardware TWI enabled. currently we are still using the c0 revs here and get twi and s110 both working by using the softdevice twi, which drains probably more power than using a hardware twi driver. I was using an other hardware twi from here to get rid of the ppi by using softdevice calls but as it turns out the power consumption while using this version had peaks of like 3-4mA which is really way to much. with software twi its getting better but still need ressources and power as well. Do you maybe can provide me with a working hardware twi driver which will work with softdevices and the c0 rev?

    Thank you ME_
