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.

// 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)

https://askubuntu.com/questions/58119/changing-permissions-on-serial-port The issue with the permissions for /dev/ttyACM0 can be permanantly solved by adding yourself to the dialout group. You will have to logout and then log back in before the group change is recognized. You can do this with sudo usermod -a -G dialout terrik if terrik is your username.
