Displaying Text from Datalogger shield on OLED SSD1315 (arduino-seeds)?

[seph22]

@StefanL38

String myTestStr = "ABC";
    Serial.println(myTestStr);
    Oled.println(myTestStr.c_str()  );

This one also doesn't work; SoString and c_str -ring can't be use with OLED because of limited RAM on the Uno _
Which reminds me that I used String at the beginning of the code String text; so that's also why Oled.println(text) didn't work then

If you have questions about anything just ask

Really thank you ! I am using the website you gave me and learning from the beginning Electronics Course for Beginners because there is a lot of basics notions I don't understand yet

About the code, here I am a bit confused about what need to be put there exactly, what is myFixedText referring to please?

@StefanL38

#define dbg(myFixedText, variableName) \
  Serial.print( F(#myFixedText " "  #variableName"=") ); \
  Serial.println(variableName);

Thank you!
