The primary target audience of the USB08 Reference Design consists of developers focused on microcontroller firmware and hardware, as well as those dealing with Windows driver and application software issues. USB (Universal Serial Bus) serves as a standardized bus interface...

USB Printer Share Switch Circuit

This simple device enables two computers to share a single USB printer or other USB devices, such as an external flash drive, memory card reader, or scanner. A rotary switch is used to select the PC that will be connected...

PIC USB Interface

The second program sends "Hello world" to the PC. By default, the board utilizes the Virtual COM Port (VCP) driver, allowing output to be viewed using Hyperterminal or similar software; PuTTY is recommended. The setup is straightforward: upon connecting the...

USB to RS232 converter

The FT8U232AM requires a small number of external components to produce a device that converts USB to TTL level RS232 signals. All that is needed is a TTL to RS232 converter to provide the 12V RS232 logic levels. The FT8U232AM...

model RC as USB Joystick

Model aircraft pilots utilize PC flight simulator software to practice handling model aircraft without risking damage to real models. It is advantageous to use the actual model aircraft remote control (RC) as the input device for the software, necessitating an...
