: It does not support many newer PIC18 parts released after 2013. For any modern "K42", "Q10", or "Q84" series chips, you must use the MPLAB XC8 compiler instead.

Version 3.47 was one of the final releases in the C18 lineage (followed shortly by v3.47 with later patches, but generally considered the last stable major build before the XC8 migration). : It does not support many newer PIC18

C18 3.47's "best" optimization will aggressively optimize interrupt routines. Use the #pragma interruptlow and #pragma interrupt directives explicitly and mark any shared variables as volatile . Example: or "Q84" series chips
