Unable to compile with Arduino FastLED library
-
I'm attempting to use the FastLED library with the Spresense. I added the #include "FastLED.h" to the
"File → Examples → MultiCore MP → Boot → Main" program as follows:
#include <MP.h>
#include "FastLED.h"void setup()
{
int ret = 0;
int subid;Serial.begin(115200);
while (!Serial);/* Boot SubCore */
for (subid = 1; subid <= 4; subid++) {
ret = MP.begin(subid);
if (ret < 0) {
MPLog("MP.begin(%d) error = %d\n", subid, ret);
}
}
}void loop()
{
MPLog("loop\n");
delay(1000);
}
The FastLED.h library is installed and compiles on my Arduino Uno. When I try and compile with the Spresense I get the following fatal error which I don't know how to resolve :
In file included from C:\Users\Don Wile\Documents\Arduino\libraries\arduino_624712/led_sysdefs.h:34:0,

compilation terminated.
exit status 1
Error compiling for board Spresense.
Your help is most appreciated. Thanks.

Hi @thedubdude
I installed the FastLED library from through the Arduino IDE . The FastLED lib seem to have very architecture and environment dependent code that has not been ported to Spresense/Nuttx.
So you, or somebody, will have to port it before it will build for Spresense.

That's too bad. The FastLED library is used by many Arduino users, including myself. That it doesn't work with the Spresense is a show stopper for me. I'm not skilled enough to try and port it to the Spresense. Thanks for your help.
