Hopefully someone in the E2E community is familiar with this problem......
I'm bringing up a new board and I am using a MSP430F5508 to talk to my CC1101 radio. On the Rx side I am using the Chipcon Evaluation Board into a header that goes directly to my CC1101 and software controlled using the SmartRF Studio7 software tool.
On the Tx side I am attempting to communicate between the Rx and my board in this case the Tx side. So far I haven't been successful with the wireless communication link so I am listing my code here with hope that some of you experts can let me or make me aware of what it is that I am missing:
#include "A_Common.h"
#include "Spi.h"
#include "Io.h"
#include "CC1101.h"
#define CMD_SRES SPICommand(0x30) // Reset chip
#define CMD_SFSTXON SPICommand(0x31) // Enable calibrate of freq synthesizer
#define CMD_SXOFF SPICommand(0x32) // Turn off oscillator
#define CMD_SCAL SPICommand(0x33) // Calibrate then turn off
#define CMD_SRX SPICommand(0x34) // Enable RX
#define CMD_STX SPICommand(0x35) // Enable TX
#define CMD_SIDLE SPICommand(0x36) // Stop RX and TX and enter idle
#define CMD_SWOR SPICommand(0x38) // Start RX wake-on-radio poll
#define CMD_SPWD SPICommand(0x39) // Enter power down mode
#define CMD_SFRX SPICommand(0x3A) // Flush RX fifo
#define CMD_SFTX SPICommand(0x3B) // Flush TX fifo
#define CMD_SWORRST SPICommand(0x3C) // Reset WOR
#define CMD_SNOP SPICommand(0x3D) // NOP
