no one here has pexsimism about anyones ability
I get a build error:
And what have you done to debug this ?
Share your all code.
As a beginner (if I may describe you as such) I think you need to ask yourself what is the easiest processor and tools you can use. You've opted to use PICKIT3, little 16 bit processor, with an unsupported open source set of software tools that produce cryptic error messages, and doing it all on Linux, frankly you are asking for problems.
With the line of code change it's working but the timing is too fast==about a minute or more per hour.
And what do you think the reason for this is ?
You asking me to trust reality but the truth cannot be trusted as a schizophrenic. The trance is in a physical form, that's why my mind cannot process--the mental aspect has turned physical and should not be that way. You're recognizing my physical reactions because it makes sense (such as writing this post) and you're not recognizing my disability. My scope of understanding is very limited because others do not recognize my traits. I don't know how to debug, debug the program. It has always been my will to try hard, but I don't have the requisites. My body may be able to communicate effectively but my mind is not being supportive. I'm functioning as a child in a man's body who's mind has failed to develop at this stage. I would love to understand the program but I can't. Unless I can change the fabric of belief to correlate with me, I remain in a coma. I'm able to have an impression but I am unable to translate that impression into functionality. I am not irresponsible but unknown conditions make me appear to be that way. For my years I have seen psychiatrists and some therapists, they have failed to recognize me for who I am. I guess I'm in shutdown mode.
I'm sorry to hear this

It still looks complex and difficult to me. AI is helpful.
AI produced this attached code. There is about a second drift slower overnight.

You will not progress unless you trust people, my advice could simplify your work. Use a mouse and a powerful - free - IDE, use an MCU family that has a lower barrier to entry than the feeble outdated little 16 bit PIC and find much more helpful online information than you currently can.
I am using a clock I built that works on the timing module I removed from the little clocks with the analog dial that work with the AA battery. It's very accurate and uses a 32, 768hz Crystal. It has the same type of movement like a wall clock, only smaller and cost about three or four dollars. I had to add two diodes and two transistors for a driver circuit along with some resistors to raise the pulse level to about five volts. I want to do something new for the reference clock signal that's why I want to try a microcontroller for the one hertz this time.
It does seem I'm stubborn but I believe it's not really Ron, it's some other identity occupying my body--probably the Antichrist. I'm not using a pic board, I'm using a microcontroller and a breadboard with the pickit3 programmer. Many years ago I have written simple software with qbasic like to create random numbers on an IBM Thinkpad 340. I only started using c when I got the microcontroller-I don't know it's intricacies. I'm not a student studying electronics or computers but I've learned electronics in high school, back in 1980 I graduated with a technical diploma in electronics and we were supposed to go to college but I didn't because of my illness or that I was distraught about life. High school was very difficult especially math class. Somehow how to program the microcontroller will sink into my brain. I must say I'm happy with the progress I've made with the pickit3. It works great, why would I do something different, I just have to learn a little code. I'm not trying to do something extraordinary with the microcontroller, so I'm satisfied although it's old.
If I use a 4mhz crystal and a 1:4 prescaler I get 250,000hz at 4uS. 100mS/4uS=25,000 ticks. 65,536-25,000=40,536 or Ox9E58.
With a 4mhz crystal and a 1:4 prescaler I get 250,000hz =4uS. 100mS/4uS =25,000 ticks. 65536-25000=40,536 or 9E58. TMR1H=Ox9E line 18, TMR1L=Ox58 line 19. Would line 22 be the same? How about line 36 using a 1:4 prescaler. Please explain these two lines.
