Hallo @all,
Ich Ich habe hier ein kleinens Temperaturschalterprojekt mit Tiny85, LM35, BC517 usw.
zum Programmieren wolte ich mir auf dem Tiny die Werte per SoftwareSerial ausgeben lassen.
Im Programm is es daher nötig Float to String zu Convertieren.
Wenn ich nun meinen Code für den Tiny Kompilieren will bekomme ich eine Fehlermeldung

Wenn ich den Code Allerdings für den Duemilanove Kompiliere Funktioniert alles...
Habt ihr ne Idee wie ich das anders machen kann?
Hier mal der Sketch
#include <SoftwareSerial.h>
SoftwareSerial mySerial(2, 1); // RX, TX
int i=0;
float temp=0;
float aIn;
String tempstr;
char buf[10];
void setup()
{
digitalWrite(4,HIGH);
digitalWrite(5,HIGH);
mySerial.begin(2400);
}
void loop()
{
int pot=analogRead(3);
// mySerial.println(pot);
if (i<=49){
aIn = (5.0 * analogRead(2) * 100.0) / 1024;
temp=temp+aIn;
i++;
}
if(i=49){
temp=temp/49;
i=0;
tempstr=dtostrf(temp,4,2,buf);
mySerial.println(tempstr);
temp=0;
}
// delay(50);
}
Hoffe jemand von euch weis weiter.
Danke schon mal fürs Lesen,
Gruß derRobert
