convertitore UART-USB basato su pic 18f4550

ciao a tutti sono nuovo del forum, magari l'articolo è già stato proposto ,quindi vi chiedo scusa anticipatamente.

cmq il problema è il seguente :

1) sono andato sul sito www.droids.it/cmsvb4/content....cdc-stack-v2.7

2) ho scaricato il sorgente a fondo pagina www.droids.it/downloads/USB_Stack_v2.7_CDC.zip

3) volevo adattare il codice preso da www.droids.it/cmsvb4/content....cdc-stack-v2.7 in pratica solo il file HardwareProfile - PICDEM FSUSB.h per poterlo adattare alla mia scheda basata su pic 18f4550 la quale sul port B ha i led e sul porto C ha i fili per la seriale (pin 7-6) e i pin usb (5-4) e sul porto A ha 2 interruttori (pin 4-5) e 2 pin sono per la seriale per la sincronizzazione (1-2)...

è giusto scrivere cosi?

è giusto? ho dimenticato qualcosa o fatto qualche errore, la scheda è realizzata su 1000fori quindi posso modificarla.

il fatto è che volevo ragruppare gli ingressi su il porto A le uscite sul porto B
e usare il porto C per la seriale e la usb.
grazie

Benvenuto nel forum.
Se non sbaglio il progetto che hai scaricato e vuoi modificare è a sua volta una modifica dello stack USB CDC contenuto nel Microchip Libraries for Applications.
Personalmente non ho mai modificato il file HardwareProfile - PICDEM FSUSB.h (a parte in caso si utilizzi il bootloader) non credo sia necessario in quanto contiene solo define.
Ti consiglio di leggerti la guida di Mauro Laurenti "Leggere e Scrivere dati via USB Emulazione porta seriale (Classe CDC)" e scaricare direttamente la nuova Microchip Libraries for Applications.

Ciao,

effettivamente ti consiglio anche io di partire direttamente dallo stack Microchip e non uno modificato e proveniente da quello Microchip.

Una guida la trovi nel seguente tutorial , ma controlla anche il progetto Freedom Light e EasyUSB .

Saluti,

Mauro
