You will therefore need two USB to MicroUSB cables,. The PS2 port has two wires used for communication: a clock line, ps2c, and a data line, ps2d. Data transfer rate of 12Mbps supports wide variety of desktop peripherals such as MODEM, audio, video devices, telephones [21-23]. We shall be using the RS232 UART in our experiments, which is connected to a USB socket on the board via a Cypress CY7C64225 USB-UART bridge. In this post we will discuss logic and interface of a matrix keypad (4x4 for this post) with microcontroller to reduce the number of port pins required to read a certain number of inputs (digital). This means you're free to copy and share these comics (but not to sell them). In fact I had known this chip for quite a long time, as it frequently appears in the BOM of budget FPGA-based designs that provides USB connectivity. For that i will generate the bit stream in XILINX. Verilog Edition — PDF. It is a solution similar to USB On-The-Go (similar term for SATA is used for unrelated devices), where the same connector is used to interface a smartphone to the host PC (PC is a host, a smartphone – a device) and to connect a keyboard or other device when a phone becomes a host. It requires minimal external components. Finally, for projects involving a UART this same connector can be used to communicate with the FPGA via a your computer keyboard. USB Solutions.
