The optical navigation device having a fast read mechanism and the transmission interface
2011
The present invention discloses an optical navigation device having a fast read mechanism and a transmission interface, the transmission interface for a host and a controlled terminal, and a trigger channel comprising a data transmission channel. Trigger channel before data transmission may be provided to the master device to transmit a trigger signal to the controlled terminal. After the data transmission channel controlled terminal receives the trigger signal to the controlled terminal to transmit data can be read to the host. Host and applies a predetermined controlled end data transmission protocol, the transmission data can be read directly, eliminating the need for a transmission with a read address data dependent.
