MOUSEBTN_LEFT_MASK 0x01 // Left button buttonMask - the following values may be ANDed to press mouse buttons: wheel - amount to tell the PC the mouse wheel has been spun (-127 to 127) y - the pixels to move in the vertical direction (-127 to 127) Note: this is in relation to the current mouse position, not absolute x - the number of pixels to move in the horizontal direction (-127 to 127) Starts the USB driver, place in the Arduino IDE setup routine: The code works for both the Pro Trinket 5V running at 16 MHz and the Pro Trinket 3V runningat 12 MHz. You can refer to the examples on the following pages to see how they are used. The functions in the library for interacting with the USB port and sending text are shownbelow. See the tutorial All About ArduinoLibraries () on installing the code into your Arduino IntegratedDevelopment Environment (IDE) for your use.ĭownload the Pro Trinket USBMouse Library

() You can downloadthe code from the link below. Software LibraryThe Pro Trinket Mouse library is available on GitHub. Pro Trinket can emulate a computer mouse with two examplesto demonstrate translatating movement into on-screen cursor changes. Using the Pro Trinket as a USB keyboard is demonstrated in an earlier tutorialhere (). Examples of HIDs are keyboards, mice, joysticks, gamepads, etc. For example, via the USB 1.1 protocol, you can build low speed USB Human InterfaceDevices (or HID). You can, though, use the connection toemulate some basic USB 1.1 devices via an Arduino software library presented in thistutorial. OverviewThe Pro Trinket's USB connector is used for uploading sketches, but the connector is not afull USB port due to lack of dedicated hardware.
