One micro-controller acts as a master and +the other is the slave. These are connected by four cables, often in a +TRRS cable, which can then communicate serially between each other. +Power is also communicated through that wire. Then, when a key is +pressed, it is sent to the master controller, which then sends the right +keycodes to the computer. |
