CC1101 driver for TMS320C6713 DSK

CC1101 driver for C6713 DSK

Description: The Code is based on the panstamp CC1101 library for Arduino. This code demonstrates transmission and reception (without interrupts) of arbitrary data length/type from the CC1101 radio chip attached to the GPIO pins of the 6713 through J1 extension header. The SPI between radio and 6713 is implemented by bit-banging the GPIO. Two C6713 DSKs and two CC1101 radios are needed for this demo.

CC1101 Sub-1GHz Transceiver Current radio settings for the radio can be found in the cc1101.h file. To change these settings simply copy/paste the exported registers from smartRF studio. Basic current settings:

• Base frequency: 315MHz
• Modulation format: GFSK
• Data rate: 50kBaud
• Deviation: 25kHz
• Channel number: 0
• Channel spacing: 200KHz
• TX power: 12dBm

GPIOs that bit-bang SPI are defined in bitbang_spi.h header file.

• SCK GPIO_13
• MOSI GPIO_3
• MISO GPIO_8
• CS GPIO_0
• GDO0 GPIO_9

Note that in order for SPI to work GPIOs have to be functional therefore SWITCH 4 OF THE DIPSWITCH SW3 (NOT SW1!!!) HAS TO BE ON-CLOSED
