Analizator Spectru

pe acesta l-am realizat acum 1 an in urma si functioneaza, scuze pentru calitatea pozelor. Am transpus si cablajul in SL.

acum am facut unul cu Mega8, insa cred ca din cauza displayului, rapiditatea e mica si nu functioneaza

In datasheet scrie sa leg pinii 3 si 9 pt bar mode...nu stiu ce inseamna asta da oricum i-am legat...ar fi o idee sa-i despart?

Gresit. Trebuia sa conectati pinul 9 la masa (sau sa-l lasati liber).

Am inteles. Multumesc pentru ajutor. O sa incerc dupa ce o sa-mi repar amplificatorul pentru ca acum mi s-a ars transformatorul...a iesit fum din el :)).
