There have been a few posts here in the last few days, that are really irritating. Some of these always happen, but the 'rate', and 'level', have become silly. Now your question, is along the line of "I'm having trouble driving my Toyota. Please help". Then it is followed with "There are lot's of examples for a GM". Without knowing _what_ you are trying to do, and _where_ you are having problems, we cannot asnswer.
People here (despite trying hard), are not able to read mind's across the internet. If you think for a moment about the 'driving' example, if somebody posted that they were having trouble changing gear, then somebody might be able to post asking if they were declutching, and pushing the gear lever in the right direction. There are several dozen examples, supplied with the compiler, that show how to interface with varous chips, how to use the serial port, how to do basic jobs like scan a keyboard, and print a message. These are capable of forming the basis of almost any 'simple application', and indeed of many far more complex tasks. Also the 'examples' for other compilers, can be moved to CCS pretty simply. So.ask a question that is specific, rather than a general (and unanswerable) question. In general, you always need to say what you want to do a 'simple application', is about as specific as "I want to write a book"...

Best Wishes

Henzces,
You say C18 has examples, whats wrong with the SIX examples that come with CCS C in the EXAMPLES directory? They look pretty good to me.

Several are even written specifically for the 18F4550...

Please if somebody was able to me to help...
I am using the example of CCS with HID " ex_usb_hid.c ", with a PIC18f4550.
with PIC there is not problem I already got to transfer the program inside of the 18F4550 and the same worked without problems.
When I connect PIC to the computer PC the same it detects without problems a device HID
However I would like to ask help of a software to VISUALIZE the values sent by PIC for the
PC, that values are a BIT (read of a switch) and an analogical word read by AIO.
Does some program exist to visualize that through a HID device USB?

Thank you

Thank you very much for the answer Darren,

But could you tell me which the name of that program for PC?
For me to find in the CD of installation of CCS?

Thank you...

It doesn't come with CCS, it comes with their USB development kit.

Somebody could tell me if a software already exists for USB
ready to read the data of PIC?
Which the name of that software?

Thank you
