// Data may include any number of ANT packets, with no sync byte or checksum.
// A read from the driver may return any number of ANT HCI packets.


// ---------------------- REQUIRED

// Which chip is this library being built for:
#define ANT_CHIP_NAME                        "TTY"

// Set the file name the driver creates for the ANT device:
//   If chip uses separate command and data paths:
#define ANT_COMMANDS_DEVICE_NAME             "/dev/smd5"
#define ANT_DATA_DEVICE_NAME                 "/dev/smd6"
// OR
//   If chip uses one path:
// #define ANT_DEVICE_NAME                      "/dev/Z"

	
// Set to the number of bytes of header is for Opcode:
#define ANT_HCI_OPCODE_SIZE                  0
 	
// Set to the number of bytes of header is for Data Size:
#define ANT_HCI_SIZE_SIZE                    1
 	
// Set to the number of bytes of header is for Sync:
#define ANT_HCI_SYNC_SIZE                    0
 	
// Set to the number of bytes of footer is for Checksum:
#define ANT_HCI_CHECKSUM_SIZE                0
 	
// ---------------------- OPTIONAL

// If hard reset is supported, define ANT_IOCTL_RESET
// #define ANT_IOCTL_RESET                      _IOW('U', 210, int)
// #define ANT_IOCTL_RESET_PARAMETER            (0)

// If the chip sends flow control messages:
//  Define the Opcode for a Flow Control message:
#define ANT_MESG_FLOW_CONTROL                ((ANT_U8)0xC9)
// AND
//   define the message content:
//     That signals Flow Go:
#define ANT_FLOW_GO                          ((ANT_U8)0x00)
 	
//     That signals Flow Stop:
#define ANT_FLOW_STOP                        ((ANT_U8)0x80)
