Ciao a tutti, mi chiamo Alex. Sono un appassionato di elettronica,campo in cui mi sono diplomato tardivamente, lavoro come tecnico informatico freelance.
Sono a chiederVi una dritta su come programmare dei ATMEGA328P-PU in modalità standalone con oscillatore interno 8Mhz.
Premetto che parecchi anni fa, quando sono venuto a conoscenza di questo fantastico controller mi sono innamorato...tanto da "sfornare" molte idee, anche programmando via ISP.
Dopo tanti anni, mi ci sono rimesso...ma ho perso parecchie "novità".
Parto dal presupposto che programmavo con un USBasp 6 Pin(penso sia un clone), che dovro; quasi sicuramente aggiornare, visto che avr me lo notifica nell'output .
Quindi sono tornato a programmare con un MEGA2560 come ISP, inoltre, dal forum(vi ringrazio ancora per questo) ho letto che ci sono nuovi sorgenti da applicare all IDE nella fattispecie MINICORE...
Quindi; installato MINICORE, impostato tutto il necessario per configurare il micro ricevente, ricontrollato le saldature e il cablaggio, condensatore su reset(RST-GND 10uf)e come ultima spiaggia impostati i fuse dal calcolatore su engbedded.com....niente.
Sono arrivato ad un punto che dall'output; che posto di seguito, si evince una corretta scrittura/rilettura, ma poi lo sketch BLINK non funge...tutto morto.

Lo sketch usa 1030 byte (3%) dello spazio disponibile per i programmi. Il massimo è 32768 byte.
Le variabili globali usano 9 byte (0%) di memoria dinamica, lasciando altri 2039 byte liberi per le variabili locali. Il massimo è 2048 byte.

avr mi ringrazia in continuazione ma vorrei che il micro funzionasse... 
Qualche idea che mi è sfuggita?
