Hello Friends..
I am very new in the field of microcontrollers. I studies PIC 16F84. Now i have decided to learn microcontroller with PIC 18F4550. I want to do programming in C. So from where should i start. I have downloaded PIC C 18.PDF file and i have PIC C.PDF. I have to learn C also. So i have to start microcontroller with PIC 18F4550, program it in C and first learn C also. Kindly guide me.
 

Dear Sir ckshivaram, i read PIC complete discussion for all and it was great source of information on PIC. Only after reading this topic , i decided to work with PIC 18F4550. From this topic only, i came to know about PIC C 18. Took over view of PIc C 18.PDF and found it very complicated. I think it is because it is dealing with inside of assembler and library functions which i will need at little higher level. So for the time being is it good to read "An Introduction To Programming The MIcrochip PIC In C by NIGEL GARDNER" ? And for PIC 18F4550 details , i have downloaded Data Sheet.
 

You can refer the **broken link removed** here. The programming given is for MikroC but I hope that'll help you out.
 
Is microC different from Hi-tech C?
 

One of the best PIC tutorials, I've come across:


**broken link removed**

They cover both the baseline and midrange PICs using assembly and Hi-Tech C Compiler. By the way Microchip purchased Hi-Tech so you will most likely see the two compilers merged into a single offering.

You can easily adapt the Midrange Gooligum PIC Tutorials to using your PIC16F84.

Very different.
 

I also love **broken link removed**. They cover a bit of all.
I also think Mikroc PRO is a good idea to beginners. It has a very good user guide and easy interface.

To star I recommend the PIC baseline range, after have good understand regarding SFR, register, memory, interrupt, I/O you can move forward to midrange and so one...

Good luck!

I want to work with PIC 18F4550. So Kindly guide me for PIC 18F4550. I saw Gooligum PIC Tutorials but all the tutorials are w.r.t PIC 16FXXX. No doubt , they are very well explained.

@cabelyn : Sorry for being noob. What exactly is baseline range and midrange of PIC microcontrollers. What i understand is that it is a classification on the bases of how advance a processor is. So in which range PIC 18F4550 falls ?

@sumit_sharma : The tutorial you suggested is very useful. It has different approach for teaching PIC 18F4550. This tutorial puts a condition in front of you and explains how to achieve it. I like this method of learning.

this site shows how Microchip classify its microcontrollers.
I understand you want to use the 18F4550, but particulary I`d like to start from the beginner.
I did it and I think it`s good to have good knowleged from the very basics, so you can move on step forward.

Considering you have limited embedded C experience with the PIC, I thought you might want to walk a little before you run. However, if you want to jump into the fire with both feet, be my guest.

I have not come across any tutorials covering C programming the PIC18F series which comes even close to the caliber of the Gooligum Tutorials. I do have a couple of books in my extensive library which cover the PIC18F series and C programming:

SD Card Projects Using the PIC Microcontroller - Covers all facets of the PIC18F using the Microchip C18 Compiler

Microprocessors: From Assembly Language to C Using the PICI8FXX2 - Covers Hi-Tech PICC18 Compiler

Advanced PIC Microcontroller Projects in C: From USB to RTOS with the PIC 18F Series - Covers MikroC Compiler

All three books are in the $20-$30 range, I have other text which covering the PIC18F however their prices are $100+ and frankly I believe it's hard to beat the three books I've listed above for the money.

Hi,
Download and read the PIC18F reference manual. There also the different parts are explained carefully. You can find it here:

@Tahmid : The link you provided does not belong to PIC 18FXXXX. It covers PIC 16FXXX series.

Perhaps i am wrong. I thing the reference manual describes common concepts of PIC related to all Controllers.

You not only have exceptional technical abilities but very good sense of humour.

Does Gooligum Tutorials covers C programming for PIC 18F4550. I think it covers C programming for mid range and baseline ranges.

@ Tahmid :

Here is the PIC18C Family Reference Manual:

As i am working on PIC 18F series , the reference manual of PIC 18C series be valid for PIc 18F series?
 

PIC18C series C device is for OTP ( one time programmable)

and pic 18f has flash memory.. but they dont make much difference.....
refer this for overview
 
I was reading " PIC Microcontroller and Embedded Systems.pdf " by mazidi. What is the difference between MACRO and SUBROUTINE ?
