mplabx e xc8 problemi con libreria adc
Inviato: 12 apr 2015, 17:12Ciao a tutti,
finalmente ho fatto il grande passo a convertirmi con l'ambiente di sviluppo MPLAB X installando il compilatore xc8. Dopo la corretta installazione dei software IDE e IPE ho fatto le seguenti configurazioni:
1) Tools --> option --> embedded: ho cliccato scanfor bulid tools ed ha aggiunto il compilatore xc8 quando creo il nuovo programma.
2) Ho creato il primo progetto e ho messo la path delle librerie in: File --> Project property --> Xc8 Compiler --> Include directories --> messo la path C:\Program Files (x86)\Microchip\xc8\v1.34\include\plib --> ok --> apply.
Con questa ultima modifica riesco ad importare correttamente la liberia adc.h, ma quando provo a usare uno dei suoi metodi dichiarati e compilo viene fuori l'errore che non può trovare il metodo anche se esso è dichiarato nel file adc.h. Non contento ho provato lo stesso ad usare il metodo "OpenADC(ADC_FOSC_2 & ADC_RIGHT_JUST & ADC_20_TAD, ADC_CH0 & ADC_INT_ON & ADC_VREFPLUS_VDD & ADC_VREFMINUS_VSS, ADC_0ANA);" ma ottengo una bellissima sottolineatura rossa per tutto ad ecezzione della costante "ADC_RIGHT_JUST".
Ad ogni modo allego il mio progetto:
MAIN
USER
SYSTEM
CONFIGURATION BIT
Sapete se c'è qualche altro settaggio che ignoro da qualche parte?
Come posso risolvere senza dovermi fare la libreria da capo?
Grazie a tutti,
ciao lcua31989
