Pressing two keys (different rows and columns) Identifies which key was pressed there is only one contact point that could cause these test results. Only one key is pressed, there will be exactly one column wire which when examined will have any row wires shorted, and then, exactly one row wire.
Typically, when the keyboard looks to see what key is pressed, it looks at each column wire, one at a time, and sees which row wires are connected, or shorted, to it. Pressing one key Note: The wiring under these keys has been simplified for instructional purposes A keypress can then beĭetected as a connection made between a particular pair of column and row wires from the pressure of the key above it. Most keyboards are made of a stack of plastic sheets printed with silver ink in a grid of column and row wires, initially unconnected, underneath the keys.
Why wouldn’t keyboard hardware be able to read some keys? In more detail the hardware design of typical keyboards that limits the number of keys that can be read at the same time.

Support multiple simultaneous keys or (3) the communication protocol between the hardware and software limits the maximum number of simultaneous keys reported. Ghosting is typically the result of one or more of the following three limitations: (1) the hardware can’t read the given key combination (2) the software on the computer doesn’t Additionally, it can report seven modifier keys, one hot key, and one macro key, bringing the maximum number of reported keys to 26. Unlike partial anti-ghosting solutions which have many combinations of three keys which do not work, Microsoft’s SideWinder X4 features multi-touch technology that allows it to detect and reportĪny combination of 17 or fewer QWERTY keys. For instance, a user playing a game might think that he or she had not hit the key fast enough for the rules of the game, rather than the key not being reported by the A user of a keyboard like this might attribute the remaining errors to Of keys of that size can be pressed simultaneously while many three key combinations remain with ghosting issues. This would be a true statement about a keyboard even if only a single combination This set of keys avoid ghosting when combined with other keys on the keyboard.Īnother marketing strategy is to state that the keyboard allows “up to” some large number of keypresses. This does not necessarily guarantee that members of When a keyboard is marketed as “Anti-Ghosting” it may just refer to a particular subset of keys on the keyboard working well together. Is a result of the internal design of most existing keyboards, as will be explained below.īut my keyboard says it is ‘Anti-Ghosting’! Imagine playing your favorite video game and not being able to, say, run diagonally and fire your weapon at the same time (say, pressing a, w, and g simultaneously). On most keyboards, even some that are explicitly marketed as “Anti-Ghosting”, this happens with many three-keyĬombinations. To have disappeared are said to have been “ghosted”. The keystrokes that don’t show up on the computer or seem Ghosting is the problem that some keyboard keys don’t work when multiple keys are pressed simultaneously. The same time and have them accurately reported. This keyboard allows gamers to press many keys at Release of the SideWinder X4 keyboard featuring new anti-ghosting technology. Microsoft Hardware recently announced the But presumably, this works out to an average current of 20mA or less, even if the peak is higher.Learn about keyboard ghosting and the new anti-ghosting technology in the SideWinder X4 gaming keyboard Again, if memory serves, these are pulse width modulated, and I don't recall the duty cycle. The purists will note that these LEDs really are meant to be run at 20mA. In fact, if you can simply hold a 200 ohm resistor in parallel with one of the resistors (100 in parallel with 200 gives 66 2/3 ohms) to see if it makes much of a difference. I'd suggest you try doing one first to see if you think it's worth the effort. However, because the human eye is logarithmic in it's response, you will probably only perceive it as being a little brighter. That is: (5V-3V)/.03A = 66 2/3 ohms There nearest standard value is 68 ohms.

But if you want to take full advantage of the available current, you want to up this to 30mA. If you don't change the resistors, this would give a current of 20mA. 03A = 30mA White LEDs typically drop about 3V. (Should be marked brown-black-brown if I'm correct.) Assuming a 5V supply, and a forward voltage drop of about 2V for the red LEDs, that gives a current of: (5V-2V)/100 ohms =.
If memory serves (I lent out all of my X4's), the resistors are 100 ohms each.
