Arduino IDE (Atmega 328P Standalone) + Bewegungsmelder und Lichtsensor

[Paul (Gast)]

Hallo zusammen,

ich habe hier einen Schaltung und nun verwende ich zum ersten Mal den 
Sleep Mode um ein wenig Strom zu sparen im späteren Betrieb.
Letzendlich soll bei Bewegung ein Sensor ausgelesen werden und der 
gemessene Wert übertragen werden.

Bewegungsmelder: AMS312 Mini Modul.
+ an 5V
- an Masse
OUT an PS2 (INT0)

Lichtsensor: ALS-PT19 Modul mit 10k Widerstand auf dem Board:
+ an PD4 Atmega
- an Masse
Out an A4 des Atmega

Der ALSPT19 soll durch Pin D4 gespiesen werden, sobald der Atmega 
"aufwacht" und anschliessend soll dann der Wert ausgelesen werden, bis 
ca. 15 Sekunden keine Bewegung mehr erkannt wird.

Ich versuche nun das über die Serielle Schnittstelle zu testen, aber es 
wird nach dem Aufwachen immer nur 1x der Lichtsensor ausgelesen, danach 
ist der Wert immer 0. Erst wenn der Atmega wieder schlafen geht und neu 
aufwacht wird 1x der Wert gemessen.
Am + des ALS liegen die 5V wie gewünscht an, aber den Wert bekomme ich 
einfach nicht mehr als 1x eingelesen.

Vielleicht bin ich dafür einfach zu blöd ;-)

PS. Die X_1 bis X_10 in der else Schlaufe waren für mich nur weil ich 
wissen wollte wo genau der Microcontroller sich schlafen legt ;-)

Wie sehen deine Debug Meldungen aus?

[Stefan F. (Gast)]

Der Fehler könnte damit zusammen hängen, dass du vor dem Schalfen gehen 
alle Bits in ADCSRA löscht, und nachher nur ADEN wieder setzt:

> ADCSRA = 0;  // disable ADC
> ADCSRA |= (1 << ADEN);

Danke für den Link, leider hilft mir das nicht so sehr weiter. Was genau 
macht diese Funktion?

[Georg M. (g_m)]

Der Onkel im Video macht genau dasselbe:
PIR Deep Sleep ATMega328P
https://www.youtube.com/watch?v=7ChTq7ZHVTI

Sein Arduino-Sketch:
https://github.com/RalphBacon/PIR-ATMega328P-Deep-Sleep/blob/master/Benny_Cupboard_Alarm.ino

[Stefan F. (Gast)]

Sichere das ADCSRA Register, und stelle den alten Wert nach dem 
Aufwachen wieder her, wie Georg es gezeigt hat.
