commit a76f5bab5002d6106e612730ed9559c956a5640a Author: Ricard Rosson <[email protected]> AuthorDate: Tue Aug 11 09:02:16 2026 +0100 examples/apa102: depend on LEDS_APA102, not LCD_APA102 This example drives the APA102 LED-strip character driver: it opens /dev/leddrv0 and writes an array of struct apa102_ledstrip_s from <nuttx/leds/apa102.h>, which is provided by drivers/leds/apa102.c (CONFIG_LEDS_APA102). CONFIG_LCD_APA102 selects an unrelated driver, drivers/lcd/apa102.c, which drives an APA102 matrix as a framebuffer LCD and registers no /dev/leddrvN node at all. The wrong dependency makes the example unusable either way: with the LED strip driver enabled the example cannot be selected in menuconfig, and with CONFIG_LCD_APA102 the dependency is met but the driver the example needs is absent, so it fails at open().
