How do I install the Platform Port skill?

Run npx skillmds@latest add fastled/platform-port in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Platform Port safe to use?

This skill has not completed SkillMD's automated safety review yet. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Platform Port?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Platform Port free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

$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
Peripheral existence check FIRST — before naming any <Peripheral>_Type typedef or <Peripheral>_BASE address, verify the peripheral EXISTS on the target chip against BOTH the vendor CMSIS PAL header for that specific variant AND the chip's datasheet chapter. See agents/docs/peripheral-existence.md for the halt-on-phantom rule and the LPC804 anti-example (framework-arduino-lpc8xx#35).
Register-map authoring — use the vendor CMSIS PAL header (LPC845.h, stm32f4xx.h, nrf52840.h, hardware/structs/*.h, etc.); do not hand-roll register shims. See agents/docs/register-maps.md for the rule, the vendor-source table, and the tier-1/2/3 integration pattern.

Build System Integration

fbuild board definition (ci/boards.py)
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
