I guess many in the forum know about the "Compiled Tips ‘N Tricks Guide" That is free documents full of golden nuggets for the PIC user. It will help you get most out of your 8 bit PIC MCU. It explain the the different methods and tricks in detail. Rather than giving program examples. So it will be very helpful to all who use PIC MCUs. It is about 137 pages long. If you have not read it yet. Give it a try. Ideal for students

A programmer is useless, unless he/she are able to utelize the power of the availible tools. And herby be able to debug and simulate code. The hobbyist may not have accsess to fancy (and expensive) hardware debugging tools. But the fact is that many errors can be tracked down with the software simulator tool named MPLAB SIM.
Microchip do have something named Webseminars. The are located here http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=2795 Sorry to say but the selection menue is very awkward to use and select from. I have compiled a list. That I think will be useful for the MPLAB novice. The list include both using MPLAB and debugging. Start on top of the list and work yourself downwards. My last tips for the beginner. Then you are starting on a new project. Always use the project wizard in MPLAB. Never program without confering with the datasheet. Keep attention to details.

Thanks to6. That is a goldmine. I studied microprocessors at the university, using the M68000, but I've never played with microcontrollers. I bought a PicKit 3 and I was enthusiastic at first, then I realized I had to learn C and MPLAB IDE, and I got slowed down. I have yet to make an LED turn on and off. But I keep working at it. ;)

That is a great source of some information that would otherwise take a lot of datasheet reading to find out!

PRS, Try out SourceBoost C, I posted the code to make a blinking LED in the other thread on that topic currently in Embedded Systems, I think. I even included a .hex file for 16F627 stupidbot.

Thanks for the tip. This morning I just went over the examples using MP-LAB C18, which is free in the student version. It includes a program that blinks an LED. I've looked over the data sheet for PIC18f45k20, which is on a board that came with PIC-KIT 3 and I am in awe. I'll never go back to microprocessors! For 70 bucks I got a complete development system. For me it's like Christmas. ;)

Hello,

Microchip has a lot of application notes.
Here is the browse page:
http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1469

I have here the links for the two application notes:
http://ww1.microchip.com/downloads/en/AppNotes/00526e.pdf
http://ww1.microchip.com/downloads/en/AppNotes/00556e.pdf

Also AN607 can be handy (power-up trouble shooting):

Microchip seems to be the king of the micro-controller industry. They seem to be to micro-controllers what Intel and Microsoft are to home computers. I'll check out your links. Thanks.

Im glad somebody mentioned getting stalled on their PIC progress.

Documentation for Microchip is thorough. A single datasheet can be easily over 300 pages and they have a lot of controller families available. Doing some ballpark figures Microchip have more than 10000 pages of current documentation - updated regularly. The 16F887 family datasheet for my 44 pin dev/demo board is at version F!

Look at their website and you can find tutorial videos and nuggets like their circuity sim Mindi - which is pretty good.

Microchip is very good at documenting their products and illustrating them with examples. I'm in awe, quite frankly. I had to go to the Microchip website to fetch a download of C18 and I saw all of this documentation.

I feel like I did when at the university, overwhelmed with concepts I had never even imagined. But I like the feeling and I know that if I keep studying I'll eventually become a microcomputer guy.

I used to play with microprocessors, esp. the M6800 8 bit chip and its supporting hardware. Now it's obsolete! I even developed a general purpose computer and had modeled a math emulator using floating point algorithms using Microsoft's MASM and its IDE. But I never did rewrite the emulator for the 6800 uproc. This was a hobby and I lost interest in it when I got severely depressed. Story of my life.

Microchip and the Pickit I bought has revived this interest. I feel like a dinosaur when I read over the manuals and realize how much power is in a modern micro-controller.

Comparing any company to Microsoft is about the highest insult one can throw.
I agree with you. I had the experience of talking with Microsoft technicians for about 3 months before they got to the bottom of my early version of Vista's problems. I think Microsoft jumped the gun with Vista and put it on the market before it was really ready. But it works just fine now, so I'm happy.

However, I participate in another forum, and in an economics thread dealing with monopoly I brought up the issue of Microsoft's near monopoly with regard to the operating system. I offered up the idea that there should be a universal operating system agreed upon by the nations just like any other standard. I think some copyrights are merely legal fictions, and this is a good case for it. What if someone had a copyright on the Metric System and charged for its use? There are many many cases of universal codes and standardizations such that a universal OS for computers is not that unusual an idea.

Microchip is very good at documenting their products
Their datasheets are not all exactly right. An example: the 18F4585 has the access to CAN-specific register messed up and misdescribed.

It took me several entries to a ticket and more than 1 month to get an incomplete answer on the matter. ("The guy who knows is in vacations...")

BTW, sorry to tell this here but transcribing the list of TBs and ANs is pretty useless. When you want to see what they have on a certain subject you go to heir site.

Why to duplicate?

The application notes list was mostly an example of how much documentation they have available. I was suggesting that the readers try to find the PIC information they are looking for by checking the Microchip website.

I also mentioned that the posted list was not complete and you should check for more Application notes and Tech Briefs.

I know that having the list here is not that useful on its own.

Their silicon can have errors - not just their datasheets.

I would be interested to know how your problem turned out or if maybe your PIC had been beamed to silicon with a buggy mask. Some times the datasheets might be vague because of silicon with issues that won't behave if you were ngiven the full instructions. That is more likely if your PIC was still in the yellow early adopters phase.

I don't know when the problems you described occurred - because if you are like me then a problem from years ago, would still not be forgotten.

I kind of agree with atferrari. I think it would be more useful to just post say this link. http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1431
Then perhaps give the link to some notes that you have used and found worth to recommend to others.
