SPK_HAT: Speaker¶
Tilslut modul¶
Det findes nogle faste moduler der kan tilsluttes M5StickC. En af dem er SPK_HAT
En lille speaker, der, ligesom de andre HAT-moduler, tilsluttes let ved at sætte den 8 pins ind i de 8 huller i toppen af M5StickC.
Afspil toner¶
For at lave et musikstykke, har vi brug for at kende frekvensen/tonens høje samt nodeværdien/tonens varighed, for de toner vi skal bruge,. Frekvensen kan beregnes - eller du kan finde en liste i bunden af denne side Oversigt over Frekvenser. Kammertonen A har frekvens 440.
SPK-modulet er begrænset til at spille 1 tone af gangen, hvilket selvfølgelig lægger lidt en dæmper på de musikalske udfoldelser.
M5StickC har to funktioner i biblioteket til at lave lyde; sing() og tone().
sing() skal bruges ved at give frekvensen og derefter nodeværdien.
spk.sing(440, (1/4)*4)
Jeg ganger nodeværdien med 4, i mit eksempel fordi jeg synes den afspiller for hurtigt ellers
tone() skal bruges ved at give frekvensen og derefter en varighed i millisekunder.
spk.tone(440, 1500)
EKSEMPEL: De første toner¶
from m5stack import lcd
import time
from flowlib import hat
spk = hat.get(hat.SPEAKER)
# Giv frekvensen navn efter tonerne
C7 = 2093
G6 = 1568
E6 = 1319
A6 = 1760
AS6 = 1865
B6 = 1976
spk.tone(C7,500)
time.sleep_ms(200)
spk.tone(G6,500)
time.sleep_ms(200)
spk.tone(E6,500)
time.sleep_ms(200)
spk.tone(A6,500)
