Hi noch mal,
habe nun den ersten Teil mal soweit zusammen.
Würde sich jemand mit mehr Sachverstand den bisherigen Code mal ansehen? Es ist im Prinzip das Beispiel 12 der M256. Ich habe in der Main.c nur die beiden Funktion "void behaviour_wifiControl(void)" verändert und eine Funktion "int cmdsplit(void)" hinzugefügt.
Keine Fehler beim Kompilieren, nur die Warnung "RP6M256_12_WIFI_REMOTE_2.c:487: warning: 'x' may be used uninitialized in this function".
Meine Fragen:
Klappt das so??
und in der Funktion "int cmdsplit(void)" habe ich anstelle der "normalen" str_fill einfach eine for-Schleife gelegt. Klappt das so???
Und wenn ich den atoi-Aufruf mache, ist mein Array "tmp" mit einigen Ziffern besetzt, der Rest wurde vorher mit "x" aufgefüllt. Sieht also z.B. so aus (für 10 Einträge) : |#|3| : |2| : |5|0|*|x|x|, wenn der gesendete String dieser war: #3:2:50*
Wird das dann richtig übernommen? Das resultierende Array params sollte danach so aussehen: |3|2|50|.
Danke schon einmal! Möchte erst einen Sachkundigen Rat hören, bevor ich daran weiterbastle. Sonst wird das debugging später etwas schwer für mich.
In die untere Funktion kommt dann noch ein Funktionsaufruf für das Bearbeiten dieses gesplitteten Strings.
Hier der Code:
EDIT: Nun, was ich möchte, ist eine Remote wie die von FabianE., gepaart mit den Cruise- und Avoid-Funktionen des Beispiels 12. Nur zur InfoCode://This Funktion splits the incoming String. This String looks like: #1:30:50:0:13*. // "#" = Begin of Command // "*" = End of Command // "1" is for "driving" // "30" ist for left engine, "50" ist for right engine -> driving a curve // "0" is for "driving forwards" // "13" is just an increasing number, increased after every command #define MAX_PARAMS 6 int params[MAX_PARAMS]; int cmdsplit(void) { int cursor; cursor=0; int param_nr; param_nr =0; // Parameterarray initialisieren int i; for (i=0;i<MAX_PARAMS;i++) params[i] = -1; /* Prüfen ob der command-string gültig beginnt */ if ((receiveBuffer_WIFI[cursor] != '#')) return -1; while (receiveBuffer_WIFI[cursor] != '\0' && receiveBuffer_WIFI[cursor] != '*') // prüfen ob das ende erreicht wurde { char tmp[10]; char x; for (i=0;i<10;i++) tmp[i] = x; //Str_Fill(tmp,'x',10);//!!!!!!!!!!!!!!!!!!! cursor++; int j; j= 0; while(receiveBuffer_WIFI[cursor] != ':' && receiveBuffer_WIFI[cursor] != '*') { tmp[j] = receiveBuffer_WIFI[cursor]; cursor++; j++; } params[param_nr] = atoi(tmp); // wert auslesen if (param_nr >= MAX_PARAMS) // sind mehr parameter verfügbar als erwartet?
