Communication system and optical navigation device

摘要

There is provided a communication system including a transmission interface, a master device and a slave device. The transmission interface includes a TR/ACK channel configured to transmit a trigger signal and an acknowledge signal and a DA channel configured to transmit a normal data or a simplified data. The master device sends the trigger signal via the TR/ACK channel before data transmission begins. The slave device sends the normal data or the simplified data to the master device via the DA channel after receiving the trigger signal.

1. A communication system, comprising:
a transmission interface, comprising:
a TR/ACK channel configured to transmit at least one trigger signal and an acknowledge signal; anda DA channel configured to transmit a normal data or a simplified data; a master device sending a first trigger signal via the TR/ACK channel before data transmission begins; and a slave device sending the normal data or the simplified data to the master device via the DA channel after receiving the first trigger signal; wherein the master device and the slave device are configured to use a predetermined data transmission protocol to directly transmit the normal data or the simplified data without transmitting an address data related to the normal data and the simplified data, wherein the simplified data is a compressed data or a repackaged data of the normal data.
