◆ CCX_APD_B0_GET_RSSI
#define CCX_APD_B0_GET_RSSI |
( |
|
_BYTE0 | ) |
(_BYTE0) |
Retrieves the RSSI value which is present within the first optional status byte, appended to received data.
- Parameters
-
_BYTE0 | The first appended status byte. |
- Returns
- RSSI value.
◆ CCX_APD_B1_GET_LQI
Retrieves Link Quality Indication value, which is present within the second optional status byte, appended to received data.
- Parameters
-
_BYTE1 | The second appended status byte. |
- Returns
- LQI value
◆ CCX_APD_B1_IS_CRC_OK
#define CCX_APD_B1_IS_CRC_OK |
( |
|
_BYTE1 | ) |
((_BYTE1) & CCX_MASK(1,7)) |
Retrieves CRC check value which is present within the second optional status byte, appended to received data.
- Parameters
-
_BYTE1 | The second appended status byte. |
- Returns
- Single bit value of CRC_OK. If CRC for received data is OK, or CRC check was disabled this will be
1
◆ CCX_GET_BITS_VALUE
#define CCX_GET_BITS_VALUE |
( |
|
_BITFIELD, |
|
|
|
_WIDTH, |
|
|
|
_OFFSET |
|
) |
| (((_BITFIELD) & (CCX_MASK(_WIDTH, _OFFSET))) >> _OFFSET) |
Retrive a bit mask from a variable. The value will be shifted so that it occupies the least significant bytes.
- Parameters
-
_BITFIELD | The value containing a bitmask/bitfield to extract. |
_WIDTH | The width of the bitmask. |
_OFFSET | The offset of the lowest bit of the mask. 0 or greater. Once extracted the bitmask is shifted by this value to occupy the lowest bits. |
◆ CCX_MASK
#define CCX_MASK |
( |
|
_WIDTH, |
|
|
|
_OFFSET |
|
) |
| (((2<<(_WIDTH - 1)) - 1) << (_OFFSET)) |
Create a bit nask.
- Parameters
-
_WIDTH | The width of the bitmask. |
_OFFSET | The offset of the lowest bit of the mask. 0 or greater. |
◆ Cc1101ChipStatusState
Possible states reported in the Chip Status byte. See CCX_SB_GET_STATE.
