hello guys i want to ask about 2 things first one is i'm connecting and arduino uno attached to a usb host sheild and transferring data of a mouse coordinates to 10 arduino leonardo i'm using the standard speed 100 normal mode my wires is all about 10 cm long
i need to speed up the comm to fast mode how to make this ? and the line of code where to put it in the code and in the master or slave ?
what about the pull-up resistors ? does arduino uno includes built in pull-up resistors ? does it needs to disable it and put my own pull up resistors ? i’m using wire library
