The log file from MHI-AC-Trace.ino has the following format:
One row has 43 bytes in hexadecimal format separated by a space and represents one or more identical MOSI/MISO frames. If it represents more than one frame, then the repetition number tells you how often it appeared.
| byte # | meaning |
|---|---|
| 0 | highByte(packet_cnt) |
| 1 | lowByte(packet_cnt) |
| 2-21 | MOSI bytes 0-19 |
| 22-41 | MISO bytes 0-19 |
| 42 | repetitionNo` |
packet_cnt starts with a random value
packet_cnt and repetitionNo are usually redundant, but it can be used in MHI-AC-Trace.ino for detection of lost frames.
Please check the example MHI-ErrOpData.log. It represents a read of the ErrOpData for my AC.
