P20F04D-12L display with HUB40A interface and 16×8 2R1G1B pixels (part 2)
original article (roumanian language)
After I became familiar with P20F04D-12L display module using Arduino develelopment board, I decided to made a weather station (temperature & humidity). The first tests we presented in the previous article named P20F04D-12L display with HUB40A interface and 16×8 2R1G1B pixels.
For test I use 2 module and I create a “picture” with 32×8 pixels for clock data (hours and minutes) and a real case is:In movie named afisaj 2R1G1B cu interfata HUB40A controlat de Arduino (8) I try different type of colours and speed animatrions:
Then I made a new “picture” for temperature:and I create a string with 512 elements (32 columns & 8 rows): Now, on my display I see:After this, I made a new “picture” for humidity:and a new string with 512 elements:Now, on display I see:
I made a new movie, named afisaj 2R1G1B cu interfata HUB40A controlat de Arduino (9)
I made a weather station with AM2302 (DHT22):
using an original sketch named hub40a_test4m1s1.ino and I made 2 movies:
