79. Extract Packet Fields from Byte Stream
You receive a 6-byte data packet from a peripheral interface (e.g., UART or I2C). The byte stream format is:
| Byte Index | Field | Size |
| 0 | start | 1 |
| 1 | command | 1 |
| 2–3 | data | 2 |
| 4 | crc | 1 |
| 5 | end | 1 |
You are given the packet as an array: uint8_t buffer[6]. Your task is to extract and print each field as integer values
Example-1
Input: 165 1 52 18 119 90
Output:
Start: 165
Command: 1
Data: 4660
CRC: 119
End: 90
Example-2
Input: 170 255 255 0 254 85
Output:
Start: 170
Command: 255
Data: 255
CRC: 254
End: 85
