Errore codice progetto pulsazioni arteriose

Ho preso questo codice da internet,quando viene compilato mi da' l'errore:"class Adafruit_SSD1306 has no number named "writeLine".Mi puoi dire cosa fare,sicuramente e' una questione di librerie.Lo puoi provare e farmi sapere cosa fare.Ti ringrazio.

Codice:: #include <Adafruit_SSD1306.h> [url=https://www.facebook.com/hashtag/define?source=feed_text]#define[/url] OLED_Address 0x3C Adafruit_SSD1306 oled(1); int x=0; int lastx=0; int lasty=0; int LastTime=0; int ThisTime; bool BPMTiming=false; bool BeatComplete=false; int BPM=0; #define UpperThreshold 560 #define LowerThreshold 500 void setup() { oled.begin(SSD1306_SWITCHCAPVCC, OLED_Address); oled.clearDisplay(); oled.setTextSize(2); } void loop() { if(x>127) { oled.clearDisplay(); x=0; lastx=x; } ThisTime=millis(); int value=analogRead(0); oled.setTextColor(WHITE); int y=60-(value/16); oled.writeLine(lastx,lasty,x,y,WHITE); lasty=y; lastx=x; // calc bpm if(value>UpperThreshold) { if(BeatComplete) { BPM=ThisTime-LastTime; BPM=int(60/(float(BPM)/1000)); BPMTiming=false; BeatComplete=false; tone(8,1000,250); } if(BPMTiming==false) { LastTime=millis(); BPMTiming=true; } } if((value<LowerThreshold)&(BPMTiming)) BeatComplete=true; // display bpm oled.writeFillRect(0,50,128,16,BLACK); oled.setCursor(0,50); oled.print(BPM); oled.print(" BPM"); oled.display(); x++; }
