What it does
Platform Port is an agent skill from FastLED/FastLED. Guide porting FastLED to new MCU platforms, including int.h types, clockless drivers, SPI implementations, and platform detection. Use when adding support for a new microcontroller family or board.
Its SKILL.md is about 580 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Embedded systems. The repository describes itself as: The FastLED library for colored LED animation on Arduino. Please direct questions/requests for help to the FastLED Reddit community: http://fastled.io/r We'd like to use github… The licence is MIT.
When your agent uses it
- Adding support for a new microcontroller family
- Tasks that involve Embedded systems
Example prompts
- “/platform-port”
What it can do on your machine
Read from SKILL.md and the folder at commit ce225ed. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Platform Port loads about 580 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 212 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

$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.hwith correct primitive type mappings - Register in the
src/platforms/int.hdispatcher
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>_Typetypedef or<Peripheral>_BASEaddress, 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. Seeagents/docs/peripheral-existence.mdfor 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. Seeagents/docs/register-maps.mdfor 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-P4What 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
