I’m trying to get an Adafruit Circuit Express Seashell project to work and I get the pragma warning, but the code doesn’t run:
/FastLED-3.1.8/fastspi.h:110:23: note: #pragma message: No hardware SPI pins defined. All SPI access will default to bitbanged output
pragma message “No hardware SPI pins defined. All SPI access will default to bitbanged output”
As far as I can tell I have the latest library and IDE set up. I also noticed this in the compile:
Using library FastLED-3.1.8 at version 3.1.6 in folder: /Users/daverobinson/Documents/Arduino/libraries/FastLED-3.1.8
Could that be the problem? If so any idea how to fix it?
What type of pixels are you using?
What micro controller are you using?
Confirm the pin number you’re using for your leds is actually the output pin you think it is. (For example, you could test with a separate simple sketch that sets that pin high and read it with a multimeter.)
Have you tested your setup with the FastLED example sketches to confirm things are working before trying other code?
I believe the default pin is 17 and that is set in the code. I tried other FastLED examples all give the same compile message and fail to run on the express board.
“One other note: if you’re using FastLED with Circuit Playground, be sure to #include the Circuit Playground library FIRST and the FastLED library second, or you may run into problems.”
Also, have you deleted any older versions of FastLED from your computer?
// tell FastLEED all about the Circuit Playground’s layout
#define CP_PIN 17 //circuit playground’s neopixels live on pin 17 #define NUM_LEDS 10 // number of neopixels on the circuit playground #define COLOR_ORDER GRB
Didn’t remove the old library I added the new library via the Arduino library manager using the zip option. The new FastLED library didn’t appear on the updated list. I’ll go back and remove the libraries and try to add them again.
Thanks
