Hello again, I’ve been almost a week without posting because I have been doing some small projects for the PIC 18F4520 this weekend. Until a few days ago did not have much idea about these PICS, but they are fantastic, especially if you mix with assembler programming with Python on PC side. The videos will be released one by one, so I have time and material to write new posts. ;)

I leave with you with the first, which basically process METAR data from nearest airport, for example, the Bilbao airport now returns me this string:

LEBB 032130Z VRB02KT 9999 FEW025 17/15 Q1017 NOSIG

Once processed you will get:
032130Z Date and time of METAR – Day 3 (June) at 21:30 (Zulu = GMT) +2 hours (is summer time), so 23:30 (10 minutes ago)
VRB02KT Wind variable at 2 knots
9999 Vsibility over 10km
FEW025 A few clouds at 2500 feet
17/15 Temperature of 17 º and 15 º C dew point
Q1017 1017 millibars
NOSIG No changes are expected

We apply a pair of operations to transformknot to Km/h and to find the humidity:

Humidity = Dew point / temperature * 100 (in this case 88.2%)

I leave with you with the project:
