$ARGUMENTS

What This Skill Covers

Platform Detection Setup

Create platform detection headers (is_<platform>.h)
Define FL_IS_<PLATFORM> macros following naming convention
Wire into existing detection chain (src/platforms/)

Integer Type Definitions

Create platform-specific int.h with correct primitive type mappings
Register in the src/platforms/int.h dispatcher

LED Output Drivers

Clockless (bit-bang) driver implementation
SPI hardware driver if platform supports it
RMT/I2S/PARLIO drivers for ESP32 variants
GPIO register access patterns for the target MCU

Build System Integration

PlatformIO board definition
Meson build configuration
Compiler flags and linker scripts

How To Use

/platform-port STM32H7
/platform-port RP2040
/platform-port nRF52840
/platform-port I need to add support for the ESP32-P4

What You'll Get

Step-by-step porting checklist with file locations
Platform detection header template
Integer type mapping research and implementation
Clockless driver skeleton based on platform GPIO speed
Build system configuration guidance
Testing strategy for the new platform
