◆ PACKET_INSTANCEID
| #define PACKET_INSTANCEID |
( |
|
x | ) |
(x[0] >> 8) & 0xff |
This will get the instance ID of a packet.
Used by the tuning interface to determine the destination of an incoming packet
- Examples
- singleinstance_simple.c.
◆ PACKET_OPCODE
| #define PACKET_OPCODE |
( |
|
x | ) |
((INT32)x[0] & 0xffU) |
Get the OPCODE of the packet.
All opcodes are defined in ProxyIDs.h. Required when doing multi instance to detect the GetInstanceTable PFID and send an instanceTable reply.
- Examples
- singleinstance_simple.c.
◆ GenerateInstanceTableReply()
| void GenerateInstanceTableReply |
( |
UINT32 * |
pPacketBuffer, |
|
|
UINT32 |
numInstances, |
|
|
UINT32 * |
pInstanceTable |
|
) |
| |
Generate an instance table reply for Server based on the arguments.
- Parameters
-
| [out] | pPacketBuffer | pointer to your instance's packet buffer |
| [in] | numInstances | number of instances on your system |
| [in] | pInstanceTable | pointer to your instanceID's table |
◆ float_to_fract32()
| INT32 float_to_fract32 |
( |
FLOAT32 |
x | ) |
|
Convert audio data from floating point to Fract32 sample by sample.
- Parameters
-
| [in] | x | The floating point value that you wish to convert |
- Returns
- The converted value in fract32 format
- Examples
- LinuxApp.c.
◆ fract32_to_float()
| FLOAT32 fract32_to_float |
( |
INT32 |
x | ) |
|
Convert audio data from fract32 to float sample by sample.
- Parameters
-
| [in] | x | The fract32 point value that you wish to convert |
- Returns
- The converted value as a float
◆ awe_getNextAWBCmd()
| INT32 awe_getNextAWBCmd |
( |
const UINT32 * |
pArray, |
|
|
UINT32 |
arraySize, |
|
|
UINT32 * |
pErrorOffset, |
|
|
UINT32 * |
pPacketBuffer |
|
) |
| |
Get the next command from an array of AWB commands and write it into a packetBuffer to be processed.
- Parameters
-
| [in] | *pArray | The AWB array |
| [in] | arraySize | The size of the AWB array |
| [out] | *pErrorOffset | current position in the array (index of command) |
| [in] | *pPacketBuffer | The packetBuffer to write the next command into. |
- Returns
- AWB_NOT_DONE if processing of array is not complete
-
AWB_DONE if processing of array is complete
-
negative number if error encountered
