Sleep & nap

[Bruce]

Glad you got it working. It probably was before, but you had to wait a heck of a long time before it would wake up..;o}

Would a USB development board be good for... what?

Development boards, like say the Microchip USB dev board & meLabs USB dev boards are handy for testing things quickly without having to build your own boards or hand-wire stuff.

Definitely not necessary, but handy if you're lazy like me..;o}

Now that you have the sleep/nap/WDT stuff down pat, here's a fix for your interrupts.

This isn't what you want;
DEFINE INTERRUPT_ORG 1008h ' For Microchip USB Bootloader

It looks like you're using the newer version USB loader, so your interrupts are re-mapped to locations 0x1008 for high priority, and 0x1018 for low priority.

What you need to do with PBP to make sure it points to these re-mapped vectors goes like this;

DEFINE RESET_ORG 1000h ' For Microchip USB Bootloader
DEFINE INTHAND high_isr ' high-pri int vector
DEFINE INTLHAND low_isr ' low-pri int vector

Note that you don't need the DEFINE LOADER_USED 1.

DEFINE RESET_ORG 1000h tells PBP to start compiling all code at 1000h.

DEFINE INTHAND high_isr. When PBP see this it inserts a ORG RESET_ORG + 8 followed by a goto INTHAND, which is your high_isr routine.

DEFINE INTLHAND low_isr. Now PBP inserts a ORG RESET_ORG + 18h followed by a goto INTLHAND, which is your low_isr routine.

So you don't need to specifiy the address.

Note that your interrupt routines will need to be assembler. Something like this;

asm
high_isr
  ; do stuff here
  RETFIE FAST

low_isr
  ; do stuff here
  RETFIE
endasm

Now your PBP .asm interrupts can work directly with the Microchip USB loader re-mapped int vectors.
