| Summary: | 碩士 === 龍華科技大學 === 電子工程系碩士班 === 102 === The purpose of this study was written by RL78 G12 MCU to program register address setting of transmit power and CC110L (RFIC) state.Use SPI communication let CC110L (RFIC) module through an antenna for transmitting and receiving radio packets,the Sub-1GHz 868MHz frequency as the transmitter and receiver.
Through G12-CC110L(RFIC)wireless module application in PIR Sensor Module,Roll camera,G-Sensor module in Roll camera, and on monitoring station computer screen, alarm bell, warning lights, use wireless module to send and receive packets.When PIR Sensor senses a human action, G-Sensor module in Roll camera being shaken , wireless module can send packets.After wireless module receiving the packet Roll camera will recording,on monitoring station computer screen opened, alarm bell rings, warning lights lights up.
Using Resend mechanism, continuously send packets when the wireless module does not receive a response packet is received within the time, avoid sending out packets and cause the receiver does not receive.
