14 bytes - optional CCSDS header, default AppId=0x3bf 8 bytes header defined as follows unsigned short lenIn16b - length of this heeader plus data buffer to follow (does not include legth of optional CCSDS packet or 32b synch workd before CCSDS) unsigned short where top unsigned byte checksum - checksum of header bottom unsigned byte testType - type of test data packet (see below) unsigned short testParm - parameter related to test data packet type unsigned short taskId - id of producing task (to differentiate between different senders) 2*lenIn16b bytes of data buffer
The testType and use of testParm is as follows:
testType = TDATA_DTEST_CONSTANT = 1 testParm = 16b constant value to be repeated as data
testType = TDATA_DTEST_INCREMENT = 0 testParm = 16b start value that is incremented on each 16b word
testType = TDATA_DTEST_RANDOM = 2 testParm = seed value for ranom generator, values are 16b but appear random in all dTypes
testType = TDATA_DTEST_WALK1 = 3 testParm = 8=walk on bytes, 16=walk on 16b words, 32=walk on 32b words
testType = TDATA_DTEST_TRANS01 = 4 testParm = number of bits of 0's before all 1's in each packet
testType = TDATA_DTEST_TRANS10 = 5 testParm = number of bits of 1's before all 0's in each packet
testType = DTEST_TASKID = 6 testParm = (not used)
The data buffer is assumed to be an array of short (16 bit) data words

Analyse a self describing test data buffer for errors.
WARNING: Because of the sequence handling, this routine is no longer thread safe. It assumes a single thread is calling it and that sequences of buffer segments are received in order. |
