Hi,
You must look into the DKU 5 cable spec sheet to identify the pins, if this information is not there then google around for it.
Also determine what communication method is used by the cable, whether USB or serial.
Now the PIC you intend to use operates on 5 V DC, this means all signal levels must not exceed 5 V, doing so may damage the PIC.
Before connecting the pins, ensure what voltage level is used by cable, do not exceed the specified voltage levels, or you might damage the phone.
I think the DKU5 cable uses 3.3 V, if this is the case you have two options
1. use a 3.3 V PIC
2. use a level converter such as 74VHC08 to convert the 5 V levels to 3.3 V or vice versa.
Get back with info required then we will go to the next stage of designing the circuit.
thanks
