Thank you for your answer but can you indicate precisely where I #include "ets_sys.h" add or remove ? So far as I learn to program esp chip. I still have one question the need to modify any library that I can control 512 LEDs I tried Jinx and Pixelcontroller but I managed to control a maximum of about 488 LEDs.

edit the ws2812.c file and put the line

#include "ets_sys.h"

somewhere at the top ... and see if it gets past the error ...

Hi

Great work program works perfectly, I want to add support for http configurable by example esphttpd but it throws me this error do not know where the problem may be ?.

How exactly did you try to add this to the esphttpd project? I just added this driver to the iot_demo (setup the same as esphttpd) and it compiled fine. Here is what I did to add it to iot_demo;

added ws2812.c & tpm2net.c to the "user/" folder ...
added ws2812.h & tpm2net.h to the "include/" folder ...
edited "user/user_main.c" as follows ...
added to the top near other #includes ...
#include "ws2812.h"
#include "tpm2net.h"
added init calls to the user_init() function near the bottom ...
#if ESP_PLATFORM
user_esp_platform_init();
#endif
tpm2net_init(); // add this line after user_esp_platform_init() (above)
ws2812_init(); // add this line too!
save & rebuild
bingo!

I am guessing that you did not edit the user/user_main.c file and add the .h (header files) or call the init() functions? Hope that helps ...
