https://github.com/lexus2k/tinyproto Using this library you can easy implement data transfer between 2 microcontrollers or between microcontroller and pc via UART, SPI, I2C or any other communication channels. You don't need to think about data synchronization between points.

CoretechR Keybon is a macro keyboard with configurable layouts and functions. Integrated into each of its nine tactile buttons is a 0.66” OLED screen. Depending on which app is active on the connected computer, Keybon switches to the suitable key layout thanks to its companion software.

https://github.com/NicoHood/HID This project(1.6kstars) went through a lot of phases and has now reached a new Arduino USB-Core Library with a lot of new functions like extended HID. It also supports HoodLoader2 version 1 is no longer supported). The idea is to enable enhanced USB functions to almost all standard' Arduino boards.

https://www.youtube.com/watch?v=eoiuhPxCcM4 UDP This tutorial presents a step by step demonstration of how to transfer data between Python and Arduino using a simple UDP client server setup. The arduino is the server, and Python is the client. We demonstrate using a BMP180 pressure sensor. You can find the full lesson on our WEB site at: http://www.toptechboy.com/tutorial/python-with-arduino-lesson-17-sending-and-receiving-data-over-ethernet/

// Creates a delay between the direction pin setting and corresponding step pulse by creating
// another interrupt (Timer2 compare) to manage it. The main Grbl interrupt (Timer1 compare)
// sets the direction pins, and does not immediately set the stepper pins, as it would in
// normal operation. The Timer2 compare fires next to set the stepper pins after the step
// pulse delay time, and Timer2 overflow will complete the step pulse, except now delayed
// by the step pulse time plus the step pulse delay. (Thanks langwadt for the idea!)
// NOTE: Uncomment to enable. The recommended delay must be > 3us, and, when added with the
// user-supplied step pulse time, the total time must not exceed 127us. Reported successful
// values for certain setups have ranged from 5 to 20us.
// #define STEP_PULSE_DELAY 10 // Step pulse delay in microseconds. Default disabled.
define DWELL_TIME_STEP 50 // Integer (1-255) (milliseconds)
