Operating Mode
CC1101 main operating mode Sleep mode, idle mode , transmit mode and receive mode, sleep mode power consumption can be reduced to a minimum. Wake-up from sleep mode , enter idle mode. In addition to sleep modes, each mode can be switched between , can be configured to automatically switch . The main work CC1101 state diagram shown below , a detailed description please refer CC1101 chip specifications .
Data transmission
CC1101 hardware supports many packet processing features, such as the preamble , sync word , data whitening , CRC checksum , FEC Forward Error Correction , address verification , etc., through the SPI interface, the user only needs to transmit the appropriate command and control CC1101, send and receive data as long as the SPI data buffer can be directly manipulated . A typical packet format shown below: In addition , CC1101 supports fixed packet length , variable packet length and the infinite packet length of transmission, the type of the data packet length, its configuration and control method are not the same , the details see CC1101 chip specifications .
Programming
CC1101 register configuration values ??available SmartRF Studio tool generates, the meaning of each register , see CC1101 chip specifications . Meanwhile , we can provide complete evaluation kits and related routines , user-friendly development and evaluation module performance .
