FastLED Platform: Renesas (UNO R4)

Renesas RA4M1 (Arduino UNO R4) support.

Files (quick pass)

• fastled_arm_renesas.h: Aggregator; includes pin and clockless.
• fastpin_arm_renesas.h: Pin helpers.
• clockless_arm_renesas.h: Clockless driver.
• led_sysdef_arm_renesas.h: System defines for Renesas.

Notes:

• Interrupt policy and F_CPU definitions affect timing; keep critical sections tight.
• Check UNO R4 core defines to ensure FASTLED_USE_PROGMEM=0 and interrupt macros map to platform equivalents.

Optional feature defines

• FASTLED_USE_PROGMEM: Default 0.
• FASTLED_ALLOW_INTERRUPTS: Default 1. Enables FASTLED_ACCURATE_CLOCK when interrupts are allowed.
• FASTLED_NO_PINMAP: Indicates no PROGMEM pin maps are used.
