PS/2 protocol

The PS/2 port is a 6-pin mini-DIN connector used for connecting keyboards and mice to a PC compatible computer system. Its name comes from the IBM Personal System/2 series of personal computers, with which it was introduced in 1987.The PS/2 mouse connector generally replaced the older DE-9 RS-232 serial mouse connector, while the PS/2 keyboard connector replaced the larger 5-pin/180° DIN. The PS/2 mouse and keyboard implement a bidirectional synchronous serial protocol. The bus is idle when both lines are high (open-collector). This is the only state where the keyboard/mouse is allowed begin transmitting data Footnote 1) XT keyboards use a completely different protocol than that used by AT and PS/2 systems, making it incompatible with the newer PCs. However, there was a transition period where some keyboard controllers supported both XT and AT (PS/2) keyboards (through a switch, jumper, or auto-sense.) Also, some keyboards were made to work on both types of systems (again, through the use of a switch or auto-sensing.

  1. This means that we are dealing with a bi-directional type of protocol as each device (pc/keyboard) sends and receives commands. At first, we will take a look at the pin-out of the ps/2 connector (actually it might be also a 5 pins connector but is the same as a ps/2)
  2. gs. Data transmissions to and from the auxiliary device connector consist of an 11-bit data stream sent serially over the 'data' line. The following table shows the function of each bit. The parity bit is either 1 or 0, and the 8 data bits, plus the parity bit, always have an odd.
  3. The PS/2 mouse interface uses a bidirectional serial protocol to transmit movement and button-position data to the computer's auxiliary device controller (keyboard controller). The computer, in turn, may send a number of commands to the mouse to set the report rate, resolution, reset the mouse, disable the mouse, etc. The computer also provides the mouse with an overload-protected 5V power supply

  1. The PS2 Controller implements a bidirectional protocol for synchronous serial transmission between the host and the PS/2 device (keyboard or mouse). The PS/2 device sends information to the Controller, for example when a key is pressed on the keyboard, or when the mous
  2. PS/2 is a type of serial communication, typically used for user input devices (keyboard, mouse, bar code scanner, etc). It involves a controller (e.g. 8042 chip on PC compatible systems), the mechanical and electrical details of the communication itself, and a device
  3. PS/2 Keyboard library for Arduino. That library implements the PS/2 protocol for keyboards. You can then interface with an old PS/2 keyboard, or emulate key events to a computer with a PS/2 port. Setup Instructions. Copy the folder FidPS2 in your arduino libraries folder. Then, include the header files in your project source file

1.5.3 PS/2 Protocol The PS/2 is a bidirectional serial interface using two signals: Clock and Data. The data consists of 11 bits including 1 start bit, 8 data bits, 1 odd parity bit, and 1 stop bit. PS/2 device generates the clock signal with a typical cycle of 80µs in both host-to-device or device-to-host communications. Table 1-1 2.1 PS2 Protocol Introduced in 1987 and mainly focused on the transmission of data between Mouse/Keyboard and Computer. For keyboard PS2 implement a bidirectional synchronous protocol in such manner that least significant bit comes first. The bus is ideal when both lines are high.This is the only state where the keyboard/board is allowed begin transmitting data The PS/2 Mouse. Mice come in various flavours - serial mice, PS/2 mice, busmice, USB mice. Below a little about mice using the PS/2 protocol, since these also use the keyboard controller. A mouse has a number of buttons (1-5 is common) and must report button presses PIC18f4550 Code to Read a PlayStation 2 Dual Shock or Guitar Hero Controller The first program will configure a controller in analog mode so that all the joysticks and button pressures can be read.

I am working on a Nano project that uses PS/2 keyboard input using the standard library. It all works fine and reliably with a standard 102 key board.

I suggest you to read it out if you want to understand better what's happening in the code. The circuit. I was almost starting to solder a PS/2 connector to a pin header, when I realized that I've read that most USB->PS/2 adapters are passive kind.

The PS/2 keyboard protocol allows the keyboard to generate a clock rate between 10 kHz and 16.7 kHz. At 11 bits per scancode, 10 kHz is a massive 909 scancodes per second. World-record holder Barbara Blackburn peaked at 216 wpm ≈ 18 cps ≈ 54 scancodes/sec. on a Dvorak keyboard layout Use our USB-KM232 or USB-ASC232 to take commands from a remote computer to send keystroke and mouse action to another computer. Our protocol converters change older XT keyboards to PS/2 or USB, and can also translate PS/2 to XT for use on older computers or CNC machines that use the XT keyboard input Re: PS/2 serial protocol decoding.

Mouse device file PS/2 Controller 5 / 8 4PS/2 Mouse protocol The PS/2 mouse operates in the similar manner as the PS/2 keyboard, except the data packets are different. The mouse sends the data using 3 byte packets. Every packet consists of the relative movement since the last transmission and the button state

The PS/2 protocol has it's roots in the third iteration of IBM's personal computer. It uses two thirds of a 6-pin mini-DIN connector to transmit +5V, ground, clock and data as shown below: The protocol is explained brilliantly by these documents but I'll walk through it again here for the sake of continuity Download Synaptics PS/2 & SMBus Driver 19..19.13 (Keyboard & Mouse) Synaptics' TouchPad device drivers are customized and supported by notebook manufacturers to meet specific driver requirements for their individual products PS/2 had a richer command set, and had mouse and keyboard protocols, whereas the DIN5 PCAT interface only worked with keyboards. the DIN5 PCXT did not support the ability to control keyboard LEDs. La souris PS/2 et le clavier mettent en application un protocole série synchrone bidirectionnel. Le bus est à vide quand les deux lignes sont hautes (open-collector). C'est le seul état où on permet que le clavier ou la souris commencent à transmettre des données I have googled a bunch and haven't found anything specific about turning off TLS protocols with pssesssion.

data[2] = 0 // Y movement. When I compare this to the PS/2 protocol I see that the Status Byte has a fixed 1 bit at the position such that you get a value of 8 if all other bits are 0. This means it is working somehow, as when I try different pins for CLK or DATA, there will be no readings at all PS/2 auf RS232 Mausprotokoll - Wandler Mein Chef hat einiges an älterem, hochwertigem Laborequipment, das auf IBM-PCs basiert, die aber Sonderanfertigungen sind und nicht ersetzt werden können.

As stated in the video, the PS/2 Interface is quite easy to implement. To send a key stroke, the keyboard begins driving the clock line. On the falling edge of the clock line, the data line represents the current bit. Each keystroke is sent as 11 bits: first a start bit of 0, then the 8 bits of the scan code (least.

The last new computer I got (~year ago) came with a PS/2 keyboard. My computer I built 6 months ago has PS/2 support. I'm typing this on a PS/2 keyboard and using a PS/2 mouse. I think PS/2 is on it's way out, but it's definitely not going to die like floppy disks for probably another decade \$\endgroup\$ - Earlz Sep 26 '12 at 3:3 PC Mice come in various flavours : the BUS mouse, the standard PS/2 mouse, the serial mouse, and the USB mouse. I do not know if there are FireWire mice available but it isn't technologically impossible.. BUS mice are the oldest. They are also called ISA mice because they are usually connected to the PC using an ISA card. Everything is handled by the ISA card and the mouse soely consists of.
