Wow…interesting, …but definitely not a project for a beginner like me. 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. Someone could probably build the device you are describing, but it would be pretty complicated to design and use. LUFA is being used all over the world, in many applications – both free and commercial. Because USB is an asymmetric protocol, that is a very different problem than the one you describe with the scale. Correct me if I am wrong, but this is what I have concluded so far. By default the EM output serial data at bauds.

Usb rs converter without drivers – Electronics – Pololu Forum

I will look into that. If you are looking for this file, on my pc it is located at C: Adapting the LUFA library for the Teensy target In my previous post I directly modified the original demo code to fit the target board. For information about the project progression, check out my blog.

An alternative to this is to have the uC communicate directly via usb with the computer. It comes with loads of examples that work with several types of atmel chips.

I am using my EMA module with a voltage adaptation circuit raising the level of its RX output from 2. The device you are describing would have to receive and act on various serial commands that affect the state of the USB end, such as a command to send adaptsr reset signal on the port, a command to tell the USB device to go into a particular lhfa, or a command to read or write data from a particular endpoint.


Website template by Arcsin. That is basically all the driver needs to do; the driver does not need any low-level knowledge of how bytes are encoded on a serial line.

atmega16u2 virtual serial example using LUFA Library

As far as I 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? If you push the Enter key, usb-ds232 Carriage-Return character will be sent and usb-fs232 received back the cursor will move back to the start of the line. There is a part in the file that looks like this:. Any help or suggestions are much appreciated.

With a commercial license, you receive: I actually find it strange that no converter exists where the full conversion is made inside the converter, without the need for an operating system. Hi, I cannot give you usb-rs223 much guidance on luffa you are doing but, you might want to consider using a MAX chip or a serial adapter like our Pololu a Serial Adapter.

The following links point to third-party ports of the Jsb-rs232 codebase to other architectures than those targeted by the official release. Thanks for the information DavidEGrayson. An endpoint is a stream of data packets with an ID number and some properties. Wow…interesting, …but definitely not a project for a beginner like me. It would also be difficult to educate the users on the serial command set and how to use it.


Then you can modify LEDs. Im an electronics beginner so forgive me if this is a silly question. Click image for PDF of schematic: The library is currently in a stable release, suitable for download and incorporation into user projects for both host and device modes. After a lot of research and experimenting I can now answer my own question Apparently it is impossible to use a USB serial adapter without having an operating system at the USB end where usb-rd232 drivers can be installed.

The next problem was that this virtual serial example was based around a seperate usb joystick example. Now I better understand why there are no such converters existing.

Share Google Facebook Twitter. After installing the driver everything was hunky dory, I used putty to check the serial data coming in.
