for this macro CONFIG_BLINK_LED_RMT_CHANNEL (from esp-idf example, blink_example_main.c)

From header file it points to RMT peripheral channel number. So what is the number and where can i refer to ?

Any help appreciated. thanks.

Any CONFIG_* defines can be changed in Menuconfig (idf.py menuconfig, or whatever method your ide has for that)

ok, thanks for the info.
