do you recommend a good manual that explains well the c, for example the types uint8_t??
thanks Doesn't IAR ship it with a manual, or two? Try enquiring with the local IAR sales office. uint8_t is a typedef that explicitly defines a ''8-bit unsigned integer'', because 'C' doesn't intrinsically have size guarantees for char, int, long, etc. People often use ''unsigned char'', but a byte isn't always 8-bit, although it's fairly safe these days. As for books, K&R was always the classic reference.
