Hi, i would like to know, can we change 2pcs capacitor 22pF which is conected to crystal 20MHz with 15pF value? Hi this is very impressive and nice project. I want to make this as my college project. I am new to microprocessors and microcontrollers. I am going to ask lot of questions regarding this project. Reply 10 years ago on Introduction. Reply 6 years ago on Introduction.
Im sura anew engineer working on aproject just like yours can you help me with the pic i need to study it and im not finding anything useful about it. You hav kept the hex file for source code of pic. So if you can upload a new link regarding the same. It would be of great help.. And one more thing, i m trying out for making a project based on usb-to-usb-wireless-transfer using bluetooth.
Hello, I'm planning to use this microcontroller to read some values of sensors connected to it then send them to an android phone using the usb port.. Thanks in advance.. By ron. More by the author:.

A small C program communicates with the hardware to issue commands to set the pins of the Microcontroller.
USB controlling is cooler than that of parallel port. Rather laptops now days don't come with parallel port, so a USB port is a bit easy replacement. ZIP Download.

The documentations are better. The application notes are better. The host driver and APIs are well documented. So you may want to look at Cypress as well. Olin Lathrop. These other sources are mostly just regurgitating the standard back to you. At best they didn't screw up in the process.
Beginning the study of a specific tecnical issue with a pages reading is not that good idea. Better a smaller "regurgitated stuff". That's the advice of an old high school teacher.
And teachers are all "regurgitators". Actually that sounds like exactly the right idea. Unless you're just looking for overview knowledge, there is rarely a substitute for studying the "real" documentation.
And only pages to get into a new technology sounds cheap anyway. If you can't handle a page manual, you don't belong here, or anyplace else technical. And how many microcontroller systems did he design? You are right that the USB specification is good to read. And it is actually quite well written compared to many other standards.
Still one may not want to read it as the first step. I think I agree. I have a hard time understanding why people don't want to read datasheets, which, by the way, are free I see the point in having "an overall view" into a new technology, just to check if it will be useful to own purposes No other way.
Lathrop, is quite obvious, even to me, that a system designer has to read USB specs; but the discussion is another:how one has to begin the learning. No need of having projected and sold a lot of system to understand that. Several years back when USB was much newer I wanted to "begin the learning" to undestand it so that I would know when it would be appropriate to use and roughly what I'd be getting into on the development side.
I downloaded the USB spec, printed it out, and read it. It's all in there, and it's really quite accessible. The USB spec is well organized and is just as good for getting a overview as it is for getting the details.
