If you are looking for this file, on my pc it is located at C: Proudly powered by WordPress. You need a driver of some kind to talk to any USB device, or else the USB host will not know the meaning of the endpoints and interfaces provided by the device. With a commercial license, you receive: Sending data from a microcontroller is a pretty common requirement in a lot of the projects I work on.

The PCB schematic and board files as well as the modified VirtualSerial example joystick-less is all available for download here. You may be surprised by the amount of code involved. This meant that there was schematics of the board layout available online which came in very hany for making my own board. By default the EM output serial data at bauds. Shop Blog Forum Support. The right to use LUFA without attribution Three free hours of consultation Priority for support requests Please see the license purchase page for more details.

For information about the project progression, check out my blog. The converter I got has adaptrr FTDI chip and it does have drivers included, but I want to use it without the drivers because I plan to connect it to an Arduino and a serial printer, and not a computer, usb-rs223 there is no operating system for the drivers.


As far as Lhfa have been able to find out this is not possible, since the USB end need drivers the scale has no operating system or driversis that correct?


Then you can modify LEDs. Adapting the LUFA library for the Teensy target In my previous post I directly modified the original demo code to fit the target board.

If you enjoy my work, please consider a small donation to help my future open source efforts by clicking the image below:. An alternative to this is to have the uC communicate directly via usb with the computer. It turns out that for the VirtualSerial to work in windows you have to install drivers for it. It comes with loads of examples that work with several types of atmel chips.

One is the software-only V-USB project fourwalledcubicle.

Using a device with a USB connection seems like it would be very complex and probably not the adaptwr to go. If you are looking for this file, on my pc it is located at C: Defining the serial command set and defining the errors and status information that get reported back to the computer over serial would be a lot of work. With a commercial license, you receive:. My target is a Teensy board. It would also be difficult to educate the users on the serial command set and how to use it.

For a USB-to-serial driver, the driver needs to figure out which endpoints to use for sending and receiving the serial data, and actually use them.

atmega16u2 virtual serial example using LUFA Library

What I wanted the LUFA library to do was pretty specific — the atmega16u2 should show up as a virtual serial port so that the computer can connect and read data from it like any other serial port. The next problem was that this virtual serial example was based around a seperate usb joystick example.


The one that I chose is the atmega16u2 because it was pretty cheap and it was used the arduino uno as the usb-serial converter for the board. There is a part in the file that looks like this:. I now connect a GPS to my target. After all of the joystick butchering the example finally compiled — I plugged in the board and it was recognised as a usb device.

Usb rs converter without drivers – Electronics – Pololu Forum

Elastic Sheep Because elasticdog was already taken. Someone could probably build the device you are describing, but it would be pretty complicated to design and use. Hi, I cannot give you too much guidance on what you are doing but, you might want to consider using a MAX chip or a serial adapter like our Pololu a Serial Adapter.

I will look into that.
