SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Analyze real-time constraints in embedded LED systems to identify timing violations.

Core Features & Use Cases

Protocol timing analysis for LED chipsets (WS2812, SK6812, APA106) including T0H/T1H, reset, and tolerance checks.
Frame-rate budgeting and per-LED encoding timing to predict max sustainable FPS.
ISR latency and DMA transfer timing measurement with platform-specific considerations (ESP32, STM32, etc.).
Bottleneck identification and configuration guidance for clock and peripheral settings.

Quick Start

Analyze your embedded LED driver by running timing-analysis against your code path to reveal bottlenecks and verify timing budgets.

FAQPage Schema

How do I check WS2812 protocol timing violations on an ESP32?▼

You can identify WS2812 protocol timing violations on an ESP32 by analyzing real-time constraints in your driver code path to measure ISR latency and verify T0H/T1H tolerance compliance.

How do I calculate the maximum sustainable frame rate for my LED project?▼

Calculate the maximum sustainable frame rate by performing per-frame encoding timing and frame-rate budgeting analysis to predict max FPS based on per-LED encoding limits and peripheral configuration.

Does timing analysis support SK6812 and APA106 LED chipsets?▼

Yes, timing analysis supports SK6812 and APA106 chipsets by evaluating protocol timing including T0H/T1H, reset, and tolerance checks to verify compliance across common microcontroller-based LED platforms.

Why is my LED protocol experiencing flickering or dropped frames?▼

Flickering or dropped frames often indicate timing violations. Analyze ISR latency, DMA transfer timing, and per-frame encoding budgets to identify bottlenecks and verify your clock configuration settings.

What's the best way to measure DMA transfer timing on STM32 LED drivers?▼

The best way to measure DMA transfer timing on STM32 LED drivers is to analyze the real-time constraints of your code path to measure DMA timing and clock configuration impacts that guide optimization decisions.
