Thank you very mutch MaxGerhardt !
I really appreciate your speed to reply! and now its working !
now i have another problem i realize that platformio has problems interpreting functions that are used in loop function for example in this code:
//To use the OLED we need to include the following libraries
#include "Arduino.h"
#include <Wire.h>
#include <SPI.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
//We then need to define the pins we are using on the Arduino
#define OLED_DC 11
#define OLED_CS 12
#define OLED_CLK 10
#define OLED_MOSI 9
#define OLED_RESET 13
//#define LOGO16_GLCD_HEIGHT 16
//#define LOGO16_GLCD_WIDTH 16

drawOILPRESS(); This runs the command specified below inside the loop but when i compinling in platformio i have this :
Same error in this code :

}
String Format(double val, int dec, int dig ) {
int addpad = 0;
char sbuf[20];
String fdata = (dtostrf(val, dec, dig, sbuf));
int slen = fdata.length();
for ( addpad = 1; addpad <= dec + dig - slen; addpad++) {
fdata = " " + fdata;
}
return (fdata);
}
should I be able to download other extention to implement a vscode so that it matches the arduino environment?
cause in Arduino IDE compiling perfectly…
