from pprint import pprint

def convert_to_celsius(temperature): # Check if the temperature is negative if temperature & 0x8000: # If the most significant bit is set # Perform two's complement operation for negative temperatures temperature = -((temperature ^ 0xFFFF) + 1)

# Convert the raw temperature reading to Celsius
celsius = temperature / 16.0

return celsius

out = {} pl = "07D005500008FF5E" for i in range(0, len(pl), 4): s = int(i / 4) out[f"{s}_hex"] = pl[i : i + 4] print(f"Converting this HEX string to temperature: {out[f'{s}_hex']}") out[f"{s}_celsius"] = convert_to_celsius(int(out[f"{s}_hex"], 16)) pprint(out)

```
