If you have a suitable PIC hardware cct with ISP and an ISP cable to eg PICSTART Plus then you can compile program, groan and retry in well under a minute. STAMP has a debug mode of sorts back to its terminal which the compilers haven't but I have never found debugging at the level of programs you are liable to do with a STAMP equivalent program. Flashing LEDs program partitioning (and of course an oscilloscope) are good enough. You can also have a serial port on any pin so can add your own debug routines to any old PC as well. > I believe that there's a "fractional stamp" implementation in an 16F84 > out there as freeware someplace; uses the internal eeprom instead of > external code, with the accompanying limitations on program size. It's quite crippled and incomplete and not really worth pursuing unless you are specifically an enthusiast.
