| Looking at the datasheet (tables 17.1 and 17.2) that combination of pins is not
available for PPS on the hardware UARTs. Either one or the other (U1 or U2) but not both. You've nailed my friend ... |

| don't use them fancy PICs with PPS but..
..does THAT PIC allow PPS to configure the pins the way you want ? It might be that certain pins cannot be used for certain peripherals ?? Buried 3-400 page ... |

| Since you are using a non-standard XMIT pin and this version is a PPS chip you can try adding Pin-Select lines for the TX/RX pins. Without that I expect it is
generating a software UART which will n ... |

| I would start by making sure you are specifying a hardware UART. Some versions of the compiler can interpret your #use rs232 as a software UART and then the ISR wouldn't work
#use rs232(UART ... |

| Hello everyone,
I'm using CCS PCH C Compiler, Version 5.080, with a PIC18F47K42, and I can't figure out how to make the UART1 RX interrupt to work. The pic is connected to a GSM module, though ... |

| Thanks for your reply.
It is far more complex than what I've imagined, but yes, it makes perfect sense. Regards |
