But it’s not entirely clear how the typical text editor handles ANSI escape sequences. This makes sense, if we were talking to a terminal. Looking at the stream, you can see that the menus are proceeded with these codes: ESC [ 4 ~ Private code?Īnd item selection is simply the up and down cursor movement codes: ESC [ A Cursor up one row Turning the knob to select an option generates ANSI escape sequences for up and down cursor movement and somehow highlights the current line. The knob, already being an HID, spews forth the setup menu as if it were being typed from a keyboard. That’s nice, of course, but the surprising point is how the setup menu is implemented in the first place. The crux of the setup is this menu (which you can see in action in the first 30 seconds of the video below). One could do this kind of mapping on the PC, but many of these USB knobs can do it for you. For example, knob rotation can be set to generate up and down arrow keys, and knob press could be ENTER. Some models, like the iWit, the user can configure the mapping within the device. These generic USB knobs are normally just plug-and-play, and are used to control your PC’s volume and muting. A company called iWit makes several kinds of USB knobs which end up in many such products. But we recently encountered a generic USB knob that did setup using a text editor, like Notepad or even Vim (although that was a bit ugly). The standard.Many embedded devices that require a setup menu will use a USB serial port which you connect to your favorite terminal emulator. For those of you who are not familiar with the Powermate, it is a multimedia peripheral, which in essence can control anything that can be controlled with the keyboard in a simple, machined aluminum knob. Hi everyone, I am trying to get the Griffin Powermate installed in XP embedded. Once you install the newest driver/software package from Griffin's. Just got a Powermate control knob for my new Windows 7 圆4 PC, installed. Of course if you don’t want to shell out for the fancy hardware you could always build your own paddle controller. See for yourself in the video after the break. Now better graphics are at the tips of his fingers.

Since the clock on his ATi Radeon 5800 can be adjusted using the AMD GPU clock tool, it’s an easy choice for this application.

uses an AutoHotKey script that he wrote to capture the input from the spinner, process that information, then adjust GPU clock speed in the background. It’s a USB peripheral which is meant to be used for anything you can imagine. The actuator seen above is a Griffin Powermate 3.0.
