I use the photorestist method its not a quick but its much more acurate than the toner transfer method
when I make mine at home I watched a bunched of videos on youtube but the best one is this one

I get my Presensitized boards from jameco.com and amazon from here

hey I am new to this forum, I really want to learn about this subject.  I have read all of this post and have ordered a pic kit 2 today.  the only thing I can see a problem for now is the assembly language.  are there any good links to this language ? seems like I will need to know this before going on to anything else.  I know alot about the electronics hardware part but am lacking on the software part.  thanks

The gooligum tutorials (mentioned by Dale in post #3) may be a good start.

All the assembly instructions for the pic of your choice are listed in it's data sheet.
For getting started with a new project, the templates in the MPLAB installation folder are useful too.

Do you already know which controller you want to start with ?


Uffbasse !

yes thank you for info, I have read the post on assembly, but I was wondering is there a set of inst. for these type of chips written in assembly language.  also I will be using the  [font="arial, verdana, helvetica, sans-serif; line-height: normal; "]20-pin PIC16F690. the one that comes with the pic kit 2

The instruction set for the 16f690 is stated within it's datasheet. Regards

I'm a big fan of the PIC18 series. At this point in the game, I wouldn't bother with the PIC16 series unless there's a compelling reason to do so.

well just new to this type of chip, thing I find most difficult is the programing, I wonder if you can skip the assembly or the C lang. and just program it usung good ol mach language.  like I used to do back in the 80's with the Z-80 chip...

You can...

But it's a lot of pain.

I do not understand why people do full stuff in machine code..

(Assembly knowledge is a must -- so I can understand that. I tweak stuff in ASM every now and then)

But a whole project. I don't have that much time.

This is a bit of a generalisation but I would recommend that if you want to learn PIC's and write in Asembler, try the 16F series.

If your starting in C then the 18F would be better.

I am fully with you on that one. Smile

hi every body,i purchased pickit 2, DV164121, i want to know how to use its 44pin demo board? first thing i wanna know is where and how to connect oscillator? my supervisor recommended me to use mikroC compiler. and my task is to connect GLCD and GPS receiver. can any body help me out to find the way to make my project easy?
thank you

Hi. My suggestion would be to study the 16f887 datasheet first as well as the schematic of the 44-pin dev board so as to know the best options for your GLCD and GPS peripherals. Incidentally the 16f887 has an internal oscillator – so it “may” not be necessary to include an external oscillator.
 
In respect of your supervisor recommendations of using mikroC as your programming language, that is his/her choice and may not necessary the best choice suited to your programming ability, as programming language choice comes down to every individuals choice. However, if your assistance requirements tends to lean towards this forum, my suggestion would be Hi-tech or assembly (asm more of choice for electronic enthusiasts), as the knowledge of these two particular languages is better based here than any other languages in respect to the 16f family of devices.

Hi i'm a student who jst started learning about P16F877A
I have question i need solving
I have to write an assembly language code for flashing 8 LED in LED1,2&3; LED2,3&4; LED3,4&5; LED4,5&6; LED5,6&7; LED6,7&8; LED7,8&1; LED8,&2; LED1,2&3; .... and reverse order without using "rlf" code in michrochip p16F877A. Below is an example they have given to me. I am suppose to write a similar code without the "movwf count" and "rlf led_array,1". Please i need it today before 12noon in Sri Lanka time (i.e. +5.30)
;Declaration and configuration of the processor
LIST P=16F877A
 #include p16F877A.inc ;include the header file
 __CONFIG _CP_OFF & _WDT_OFF & _PWRTE_ON & _XT_OSC & _LVP_OFF

count   equ h'026'
led_array  equ h'027'
 org 0x00   ;the reset vector
 goto main
main  
 bsf STATUS,RP0  ;move to bank 1
 bcf STATUS,RP1  ;;;;;;;;;;;;;;;
   
 movlw 0x00  ;select & configure output port
 movwf TRISD  ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
     bcf STATUS,RP0  ;back to bank 0
 bcf STATUS,RP1 ;;;;;;;;;;;;;;;
 movlw 0x01  ;pattern select
 movwf led_array
loop
 movwf PORTD
 movlw 0x16  ;delay time
 movwf count
 call delay
 rlf led_array,1 ;left rotate the bit pattern once
 movf led_array,w
 
 goto loop
delay
 decfsz count,1
 goto delay
 return
endmain
 goto endmain
  end

I bought the PICKit 2 thinking there would be anything remotely useful that comes with it.  Nada.  Just examples and no real help with learning to program.  I read through the tutorials over at googlium, and they didn't help one bit.  I just don't get it.  It's all over my head, and I will never get it.  Would it be taboo to ask for someone to just write what I need for money?

I just started becoming familiar with the Microchip platform (& MCU's in general) a couple of months ago.
Early on, I was pointed towards Gooligum. It was an excellent tip. I purchased their development board and tutorial series (I already had a PICKit 2 programmer).
David Meiklejohn's tutorials will get you as far as you want to go, and provide a quick "ramp-up" time.
Good luck and enjoy.

Well there you go OP, you have now got 5 years of tips on how to start with PIC's
