Did you know that MPLAB has PicKit2 support ? It's built in. You don't
have to use the separate program. But anyway, those checkboxes
look like they do the same thing as the MPLAB buttons do.
I think the most likely reason for those checkboxes working or not working
might be that some programs are compiled with the NOMCLR fuse setting.
In that case, the checkboxes won't do anything. |

I didn't know for pickit 2 programmer in mplab. Thanks.
And you are right for the fuses. In the other programs, nomclr is here... |

Do not use MPLAB, use ccs ide and forget troubles. MPLAB is doing such dodgy things that you have no control over the code, when I have moved to ccs ide then I have learnt how much wrong was in my code and why it was unpredictable.

Please explain how people who use MPLAB as the IDE for the CCS
compiler have no control over their code. The user writes the C source.
The compiler compiles it. MPLAB then programs it into the PIC. Where's
the lack of control ? |

I have found that MPLAB is sometimes on occasions trying to fix broken code instead of showing the problem, ccs ide is showing the problem and is not trying to fix anything. So MPLAB is confusing the user because the user cannot learn where are mistakes made. Mainly it applies to trying to fix wrong order of commands. When I have moved my code written in MPLAB to ccs ide then I have found that it didn't work. Code was written over 2 years and I had such problems with it that it is hard to believe, I could not find errors and nobody could help me. Code was slow and unstable, sometimes moving a block of code up or down could crash the pic. CCS ide did show up front errors in structure of the code and command order. That is all, so if there are issues and everything should work but is not than it may be an issue with MPLAB itself. It is preparing the code before it sends it to compiler and it does not do it properly. Since I use CCS ide I have no issues with the code at all. To take as an example ADC functions the same code compiled on CCS IDE was returning great readings, MPLAB was returning chaos, on occasions jumping way up or down so much that I could not use ADC and had to do 50 readings and then calculate average based on it. And most of problems with my ADC was actually MPLAB itself. That is all. Next thing I have found is that one in few programs and compilations of the code is corrupted on regular bases and I needed to remove everything autogenerated by MPLAB from MPLAB and source folder and then build it up again and the same code was working but a moment ago didn't. Next issue was related to clearing rom on pic, the same story, I had to clear it on regular bases to make sure that the code is fresh and new generated. Since I use CCS IDE never ever experienced anything like that. MPLAB was in use for over 2.5 years on daily bases, CCS is in use for half year now, dos command used to control pickit 2 and all works like a charm, if something does not work then it is me. Then I have shared my experience with my friend who is lets say 30years ahead of me in C and pics and the first thing I was told was to stop using MPLAB. I hope it helps.

I don't know. I don't understand your reply. I believe we are somehow
talking about different things. For example, I have no idea what this
means at all:

How can a mere text editor (ie. MPLAB) fix anything ? |

This question is for MPLAB not me, if CCS IDE is not processing the code from MPLAB then it is not right. Do not take it as a rule but as a possibility. That is my experience only and may not repeat on different hardware. Just a hint nothing more.
