intrebare receptor IR

Recommended Posts

Am o telecomanda luat din baza protocol SONY. Folosesc un receptor IR TSOP1138. Stiu ca pentru protocolul SONY trebuie TSOP1140 sau TSOP1740. Momentan nu-l am. Ideea este ca observ ca daca tin apasat o tasta durata palierelor HIGH si LOW se schimba (bine nu semnificativ) dar din cind in cand apar si valori eronate. Intrebarea este daca de la TSOP provine aceasta eroare.
