dspic30f3011 este recunoscut de pickit2 dar cand il alimentez imi da eroare la conectare Unsupported Part (ID=00E1):post-27236-139829499511_thumb.jpgTensiunea de alimentare a dspic este de 5.08 V, schema de conexiune:post-27236-139829499519_thumb.jpgLa partea de isolare MCLR din schema am incercat diferite variante cu rezistor, cu dioada, cu si fara acel condensator si aceiasi problema. Nu il pot programa cand este alimentat. Am testat si pe PIC -uri merg fara probleme.

Probabil ca nu am fost destul de explicit. Cand spui sursa externa te referi la un stabilizator 7805 ce alimenteaza dspic?Daca da sursa externa la mine are 5.08V masurat.Cand dspic este alimentat din sursa externa cu stabilizator 7805 nu este recunoscut de programatorCand nu este alimentat din sursa externa dspic este recunoscut.Toti pinii de Vdd, Vss, AVdd, AVss sunt conectati si la sursa externa si la mufa ICSP ca in schema de mai sus, insa nu stiu cand spui "cu condensatori pt decuplare" la ce te referi.
