I've also been getting more errors with the void setup and void loop

If anyone can help that would be amazing! :slight_smile:

Edit: The compiler error has been fixed, thanks! However, I have been running into a new error.

The compiler cannot find the file WProgram.h which is no surprise as it was only used in very old versions of the IDE. Look in the C:\Users\cathe\Documents\Arduino\libraries\LED folder. You will probably find 2 files, LED.h and LED.cpp. Open both of the files in a text editor and replace all instances of WProgram.h with Arduino.h Save the files and try the upload again

I did not look at your program in detail but do you really need so many libraries ?

Thank you!

These came from just including FastLED as a library, but I don't think I need most of them.

lms2020di:

Correct. You only need this:

#include <FastLED.h>

When you do Sketch > Include Library > FastLED, it adds #include directives for each of the .h files in the FastLED library folder.

However, that wasn't the cause of the error. The cause of the error was you adding this line:

#include <LED.h>

which has nothing to do with the FastLED library. I don't see anything in your code that even uses the LED library, so you can just remove that line.

I did notice this:

pinMode(7, 5);

Please spend some time studying the pinMode reference page so you can learn how to use that function correctly:

I also notice that you are missing several semicolons.

I also notice that you are missing closing braces on the ends of your functions.
A very helpful troubleshooting tool is the Auto Format feature (Tools > Auto Format in the Arduino IDE or Ctrl + B in the Arduino Web Editor). If you do an Auto Format and then compare the resulting indentation to your intended program structure, it will quickly point you to where there is a missing or extra brace.

Another useful feature of the Arduino IDE/Arduino Web Editor is that when you place the cursor next to one bracket, it puts a box around the matching bracket. In the Arduino IDE, if the cursor is next to the closing bracket and the opening bracket is off the screen then it will show the opening bracket line in a tool tip after a short delay.

Hello!

I'm working using the FastLED library and I'm getting the error mentioned above

Here is my code,

#include <bitswap.h>
#include <chipsets.h>
#include <color.h>
#include <colorpalettes.h>
#include <colorutils.h>
#include <controller.h>
#include <cpp_compat.h>
#include <dmx.h>
#include <FastLED.h>
#include <fastled_config.h>
#include <fastled_delay.h>
#include <fastled_progmem.h>
#include <fastpin.h>
#include <fastspi.h>
#include <fastspi_bitbang.h>
#include <fastspi_dma.h>
#include <fastspi_nop.h>
#include <fastspi_ref.h>
#include <fastspi_types.h>
#include <hsv2rgb.h>
#include <led_sysdefs.h>
#include <lib8tion.h>
#include <noise.h>
#include <pixelset.h>
#include <pixeltypes.h>
#include <platforms.h>
#include <power_mgt.h>
#define NUM_LEDS 54
#define LED_PIN 7
CRGB led[NUM_LEDS];

void setup() {
  // put your setup code here, to run once:
pinMode(7, 5);
FastLED.addLeds<NEOPIXEL, LED_PIN>(led, NUM_LEDS);

for (int i = 0; i < NUM_LEDS; i++) {
     led[i] = CRGB(0,0, 255);  
}
 FastLED.show();

 void setBlue(int val); 
  for (int i = 0; i < NUM_LEDS; i++){ 
    led[i] = CRGB(0, 0, 255);
    }
    FastLED.show();
  
 
void loop() {  
  // put your main code here, to run repeatedly:
 for (int i = 255; i > 0; i++) {
     setBlue(i);
     delay(300)
 }

And here is the error message

exit status 1
a function-definition is not allowed here before '{' token

Thanks in advance! :slight_smile:

You should be aware that the compiler does provide the line number of any errors it finds.

Auto format your code with ctrl-T and you will see the problem - mismatched curly braces.

9

And you should also be aware that the error message is scrollable and contains more than just that last line.

10 
FastLED.show();
 
 
void loop() {

That's certainly not right.
