The 'LAST_IMPLEMENTED_PMEM" value is the byte address of the last
implemented program memory location for the selected processor. The
code uses this to reserve the last page of memory for writing profile
data to non-volatile program memory.
Since the PIC24HJ64GP202 has the same amount of program memory as the
PIC24HJ64GP502, just edit the line in chap15/reflow_oven.h from:
#if defined(__PIC24HJ64GP502__) || defined(__PIC24FJ64GA002__)
to:
#if defined(__PIC24HJ64GP502__) || defined(__PIC24FJ64GA002__) ||
defined(__PIC24HJ64GP202__)
Hope this helps,
