I am trying to program the chip and when I try to program it using a MPLAB ICD2 the ICDWarn0052 appears. This warning states that it cannot validate a target device. All the connections have been properly made from the programmer to the protoboard. The chip is receiving a +5V input in the proper Vdd pin. The protoboard, programmer, wires, and connection cord have all been changed and still this warning pops up. The right chip has also been set in the program project. Do you have any ideas of what the issue could possible be?
