I have just got one of the these board. Very nice. The quality is excellent. I recommend this product.

I use Great Cow BASIC as my compiler for PIC microcontrollers. Open source and very, very simple. See http://gcbasic.sourceforge.net/index.php

My code to flash the leds is extremely simple and really only a few lines long.

Code:
'   FILE:    PIC_16F877a_LED_Test.gcb
'   DATE:    01/08/14
'   VERSION: 0.1a
'   AUTHOR:  Anobium, based on the work of Andrew Davies dated 26/07/14

'  This test program will flash the LEDs connected to port D on the development board.
'  It was written using the Great Cow Basic (GCB) complier. Install GCB - you are recommended to use
'  GCB@SYN from the Great Cow Basic website.

'Chip settings
  #chip 16F877a, 4    ' Select the chip and the chip speed
  #config Osc = XT    ' Select the external oscillator

  dir portd out         ' Set all PORTD ports as outputs

  do forever            ' Loop for ever

      PORTD=0xFF      'Turn off LED's on port D
      wait 125 ms       'wait

      PORTD=0x00      ' Turn on LED's on port D
      wait 125 ms       'wait
  loop

That's a very interesting project. I will try and schedule some time in the next few days to have a closer look at it. Maybe it's something we can add to the first post to help beginners to get going with PIC devices.

I have sent Andrew a private message but it is stuck in my outbox. Is there an email address I can send a PM to?

We don't sell this product so it's not really something we can give much advise on. The only thing we have noticed is that quite a few people using 64bit operating systems have reported the same problem with this model of programmer. Quite often their solution was to disconnect the programmer in some way such as selecting a different programmer and then switching back, physically disconnecting the programmer, or downloading the pickit3 programming software, using it to push a firmware update to the programmer and then connecting it back to MPLAB. If your current problem is just related to this programmer please feel free to post in the general discussions area about it as someone who has one may be able to give you some advise. It's a little off topic for this thread which is just for 16F877A development board.
