Ciao Mauro,
Il libro è ben fatto e utilissimo. Lo stò leggendo sovrapposto ad altre letture che mi servono per il lavoro e quindi vado un pò a rilento. Apprezzo molto l'estrema chiarezza, e il gran numero di esempi.
Vorrei segnalare una cosa che non ho capito ancora se è un errore o se mi sfugge qualcosa: a pag 29 descrivi la cartella dat al cui interno c'è la cartella lkr contenete i file linker. Aprendo il file 18f4550_g.lkr nella mia directory però c'è solo scritto:

La mia versione è la 1.33, ma visto che ho ancora istallata in un altro PC la 1.20 ho controllato e il contenuto è il solito. Sembrerebbe che il file lkr non serva in XC8, ma allora le informazioni che erano in esso dove sono finite e come è possibile modificarle?
Saluti
Luca
