RF Keyboard Encoder

1 General Description

In RF keyboard system, that is divided into two parts (the transmitter and the receiver).

The eKK6511 micro-controller is dedicated to a RF keyboard encoder for single

channel RF transmitter module. The eKK6511 is scanning keyboard state, encode key

data and rely on RF Tx module to transmit data.
