  1. That document was specifically for PIC16F87x chips. The exact same bit in the PIC16F877/A datasheets is just named "DEBUG".
  2. The PIC16F87X debug hardware is documented. http://ww1.microchip.com/downloads/en/devicedoc/51242a.pdf Unfortunately the newer chips aren't, but they are probably just extending the same concept.
  3. Was any solution found? I note the CONFIG bits have not been shown. The chip will not run if the oscillator has not been set up correctly, and it will be rapidly resetting if the WDT has not been disabled.
  4. Of course, the simulator may be fine. It may just be Harmony that's not implementing USART via DMA correctly...
  5. Comes from https://www.microchip.com/forums/m1090367.aspx George is on the case. He thinks it should work, despite the "very helpful" support technician saying it wouldn't...
  6. Personally I'd just track it in putch(). Then you know there won't be any tricky way to bypass your check.
  7. You don't need to edit powerup.as if you tell the compiler about the " NVMREG" errata. https://www.microchip.com/forums/m969418.aspx
  8. We're still selling products using PIC16F877A, more than 18 years after I designed the first version. 🙂 (In the QFN-44 package though)

    We're expecting a month's worth of rain in a day tonight... https://www.theage.com.au/national/victoria/melbourne-weather-victoria-could-endure-month-s-worth-of-rain-in-a-single-day-20190205-p50vwe.html However, that's just because we're catching the fringe of the huge downpour up in Queensland. They've had a year's worth of rain in a week, over a metre of rain! https://www.theage.com.au/national/queensland/townsville-on-edge-as-dam-gates-open-20190203-p50vfp.html https://www.theage.com.au/environment/weather/how-queensland-is-being-soaked-by-an-unprecedented-monsoonal-burst-20190204-p50vib.html Their "flood mitigation" dam quickly filled up to 250% of nominal capacity before they had to fully open the floodgates, which quickly put two suburbs of Townsville under water.

    Should I mention that phpBB had this feature over ten years ago? 😉 Melbourne got to 39C today, and is heading towards 39 or more tomorrow. There's some major fires burning in the east of the state, and we've lost the use of two of the "Elvis" sky crane choppers after one of them crashed into a dam while taking on water a few days ago. (That one is still in the dam, and the second one has been grounded until they find out what happened to the first...) https://www.theage.com.au/national/victoria/total-fire-ban-declared-for-sunday-amid-fears-of-extreme-heat-20190202-p50vau.html https://www.theage.com.au/national/victoria/water-bombing-aircrane-lands-in-dam-while-fighting-fires-in-east-gippsland-20190128-p50u6s.html
  12. The "high gain antenna pointing routine" sounds just like the problems with the AE-35 antenna reported by HAL9000 in 2001! 😉 http://2001.wikia.com/wiki/AE-35_unit
  13. The User Guide for XC8 v2.0 still lists exactly the same options.
  14. XC8 has several different ways of implementing switch case. It analyses how many conditions there are, and what pattern they follow before deciding which one to use. When you read the LST file, it tells you which type it has decided to use.

    Melbourne's not too bad. Sydney has much worse humidity. We have an evaporative cooler on the house at home, and it works well on most days, except for the one or two really humid hot days.
