Hello All, so i am very new to Arduino,

Hello All, so i am very new to Arduino, ive been building light sculpturs a while although always using Dmx, now i am building one for my 8 year old, and have jumped into the world of arduino…Using the fastled library, well learning to now i have an issue… BouncingBALLS.ino: In function ‘void setup()’:
BouncingBALLS:31: error: no matching function for call to ‘CFastLED::addLeds(CRGB [60], int)’
the other codes examples, im running work fine…however this issue come up with tthis one and i have no idea why…
i downloaded the 3.0 version of fastled and running arduino 1.0.5-r2…
could someone help me to know what this is ?
im thinkng therees some issue with the versions somehere ??? i have a ton of otther questions… but right now just want to get some patterns running… and then be able to to select between them…and also to be able to control, some functions of the patterns. to create a control station for my boy to play with… the scultpure alsoo has 6 servos moving six arms:) i have around 8 days to get this all working before i leave… so all help greatly appreciated Thanks in advannce

You are going to need to show the code you are using. Use http://pastebin.com. At first hand, it looks like you are not setting up the library correctly. Try looking here as well to learn a bit more: https://github.com/FastLED/FastLED/wiki/Basic-usage#setting-up-the-leds

;The code im using is this:

float h[NUM_BALLS] ;                         // An array of heights
float vImpact0 = sqrt( -2 * GRAVITY * h0 );  // Impact velocity of the ball when it hits the ground if "dropped" from the top of the strip

i have run various other bits of code which work fine, and all seems correct when i compare to what i have working… already in terms of the setup…i have no problems with…i have been through the fastled setup annd various other examples and have had them working no problem… but with this code… theres an issue…

i dont know what it is… i was thinking that perhaps the issue is that im using fastled 3 and perhapps this was written with fastled 2 library…???

Ok, I figured it out. Change the setup code to this:

FastLED.addLeds<CHIPSET, DATA_PIN>(leds, NUM_LEDS);

When using NEOPIXEL, you don’t need to define the rgb ordering. The library already does it for ya

ok will give it a go after i cook the lasagne thanks

Rich_Love · December 4, 2014, 7:58pm
