writing usb driver in visual C#.Net.?
-
i want to write driver for my microcontroller. when i connect to microcontroller project to Pc so i want they connect eachother.and send and get datas. i think it can be.but how? serialports connect to microcontroller i think USB can connect to microcontrollers too.
What part of "you can NOT run a C# app on a microcontroller" is so difficult to understand?

How can i write usb driver software for microcontrollers? i have a poject with microcontroller. When my project connects with usb cable to PC so i want my software connects with microcontroller.i want to send data and get data from microcontroller. i wish i could explain my aim. for example when i click a button in PC side(in visual studio or delphi etc.) so microcontroller and pc can send-get datas with usb cable.
The short answer is: NO 1. PC side if your microcontroller is to show up as a special peripheral to your PC, with an entry in the Hardware list, with multi-user capabilities, etc, then you need a device driver; such drivers can not be written in any of the .NET languages, the CLR isn't capable of doing system work. if your microcontroller: 1) would be connected through a serial port (possibly using a USB-to-RS232C cable plugged into one of your PC's USB ports), 2) would not be a multi-user device 3) would not need permanent software support then you could develop an app in any language you choose, including C#. It then couldt use the SerialPort class and go without a special driver. 2. Target side microcontrollers in general don't support .NET, and most people still believe you need .NET to run a C#-based app, so no there will not be any C# code running on the microcontroller. (One could create a cross-compiler for C# and compile it to either native or intermediate language, and come up with a small virtual machine to execute it; there is a sufficient number of small Java examples around to proof it is possible; I have not seen anyone do it for C# though). :)

But no longer in 2009...okay thats right, but what if we merge the .Net Framework with the application ?

First, you'll have to find a compiler that will generate native code with the app and framework all rolled into one. There are some out there, but they cost a small fortune to buy. Next, that compiler will have to generate native code for the CPU in the microcontroller. That probably doesn't exist. Those compilers will generate code libraries that are significantly larger than the app itself. You'll have to make sure the MC has the storage capacity to hold such a large executable. Lastly, the .NET CLR depends on Windows, which the MC will not run.

Good luck!
Like I'm gonna test ? It was just an idea. Thats it...

You probably won't need to write your own driver (if you do you will need to delve into the dark world of C/C++). Find the most suitable USB class[^] for your device, implement that in you µC's code and you can use the Windows USB driver for that class. Many µC manufacturer's already have code available for most common scenarios (so you may not even need to code the USB implementation at the µC side) and some even have their own drivers already written for you for when the generic Windows drivers won't do. I experimented briefly with this with a PIC and the USB MIDI spec with sucess after a lot of trial and error - google will be your friend when you know exactly what to search for.

A new article perhaps? ;) If you do, let me know - it would be VERY interesting!
