error: 'Adafruit_PCD8544' does not name a type

[emailjakefrench]

Hi All,

I purchased the Nokia 5110 lcd display a while ago and I have an issue:
I’m using the Arduino Uno for this and I can get a scroll text program to work fine, but not graphics. I’m aiming to only make (say) Game of Life stuff, involving simple pixel points of the form:
void drawPixel(uint16_t x, uint16_t y, uint16_t color);


My issue is using the 'Adafruit_PCD8544' library with the screen – I’ve downloaded the library and can include the *h and *cpp files fine, but I get the error:
sketch_aug12a:12: error: 'Adafruit_PCD8544' does not name a type
During the line
Adafruit_PCD8544 display = Adafruit_PCD8544(7, 6, 5, 4, 3);

I think I’m doing something fundamentally wrong but can’t see what.
Sincerely and I look forward to hearing from you,

Jake

P.s. Stripped down version:

Code: Select all

#include <Adafruit_GFX.h>
#include <Adafruit_PCD854444.h>
#include <Adafruit_PCD854444.cpp>

// pin 7 - Serial clock out (SCLK)
// pin 6 - Serial data out (DIN)
// pin 5 - Data/Command select (D/C)
// pin 4 - LCD chip select (CS)
// pin 3 - LCD reset (RST)


//Adafruit_PCD8544 display = Adafruit_PCD8544(7, 6, 5, 4, 3);
// also tried this but get the same result:
//Adafruit_PCD8544 display(7, 6, 5, 4, 3);


void setup()
{               
    Serial.begin(9600);
    //display.begin();          // initiate done
    //display.setContrast(50);  // change contrast for suitable viewing
    //display.display();        // show splashscreen
    //delay(2000);
    //display.clearDisplay();   // clears the screen and buffer
}


void loop()
{
 
}

Scroll up in the diagnostic window to find the first few lines of the error messages. I suspect that is was not able to locate the library files. Most likely they are not installed in the correct location. Follow the instructions here:

Sorry, I don't think I made myself clear - this is the only message displayed when I scroll up -

pcdtest:12: error: 'Adafruit_PCD8544' does not name a type

For the code (below), i.e. the libraries can be seen - I just get the above error when at this line:
Adafruit_PCD8544 display = Adafruit_PCD8544(7, 6, 5, 4, 3);

Best, Jake

P.s. code
#include <Adafruit_GFX.h>
#include <Adafruit_PCD8544.h>
#include <Adafruit_PCD8544.cpp>

Adafruit_PCD8544 display = Adafruit_PCD8544(7, 6, 5, 4, 3);
// also tried
//Adafruit_PCD8544 display(7, 6, 5, 4, 3);


void setup()
{
Serial.begin(9600);
//display.begin(); // initiate done
//display.setContrast(50); // change contrast for suitable viewing
//display.display(); // show splashscreen
//delay(2000);
//display.clearDisplay(); // clears the screen and buffer
}


void loop()
{

}

That error means that the IDE cannot find the Adafruit_PCD8544 library. Either you have not put the library folder in the right place, or you have not given the folder the correct name.

From the github library page:

To download. click the DOWNLOADS button in the top right corner, rename the uncompressed folder Adafruit_PCD8544. Check that the Adafruit_PCD8544 folder contains Adafruit_PCD8544.cpp and Adafruit_PCD8544.h

Place the Adafruit_PCD8544 library folder your <arduinosketchfolder>/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE.

You can also refer to the library instructions adafruit_support posted in his earlier message.

Finally, this is not correct:

Code: Select all

#include <Adafruit_PCD8544.cpp>

Do not #include .cpp files. The IDE will find them in the library.
