Stap 2: WizFi250-CSI.h
Alle functies, structuur en statische waarden zijn gedefinieerd in de "WizFi250-CSI.h".
Zo, vergt uw scriptbestand alleen moeten worden opgenomen "WizFi250-CSI.h".
U moet niet bevatten een andere headerbestanden zoals stdio.h, string.h of socket.h.
Door te verwijzen naar deze "WizFi250-CSI.h", kunt u uw eigen toepassing (C-scriptbestand) schrijven.
Meest algemene functies zijn gebaseerd op de "C-standaardbibliotheek".
int atoi(char *); int atol(char *); int printf(char *, ...); int scanf(char *, ...); void *memcpy(void *,void *,int); int strlen(char *); ..........................................
Socket functies zijn gebaseerd op BSD sockets API.
int socket(int, int, int); int connect(int, struct sockaddr *, unsigned long); int recv(int, void *, unsigned long, int); int recvfrom(int, void *, unsigned long, int, struct sockaddr *, unsigned long *); int send(int, void *, unsigned long, int); ..........................................
De meeste hardware-functies van de WizFi250 zijn gebaseerd op de stijl van de Arduino.
void pinMode(int gpio, int type); void pinOut(int gpio, int value); int pinIn(int); int analogRead(int); void delay_ms(unsigned long milliseconds); ..........................................
