Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by mohitmishra786 on GitHub. Read the source before you install it.

Installation

Install the Timers Pwm Baremetal AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/mohitmishra786/low-level-dev-skills/tree/main/skills/baremetal/timers-pwm-baremetal
Enable the skill in any chat where you want it available.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/mohitmishra786/low-level-dev-skills.git /tmp/low-level-dev-skills
mkdir -p .claude/skills
cp -r /tmp/low-level-dev-skills/skills/baremetal/timers-pwm-baremetal .claude/skills/timers-pwm-baremetal

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Timers Pwm Baremetal in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Timers Pwm Baremetal on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Timers Pwm Baremetal is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Timers and PWM (Bare-Metal)

Purpose

Configure MCU timers for PWM output, input capture, and periodic scheduling: prescaler/ARR setup, compare channels, and SysTick as a simple tick source.

When to Use

Motor/LED dimming via PWM
Measuring pulse width (input capture)
Bare-metal millis() without FreeRTOS
Hardware periodic sampling trigger

Workflow

1. PWM on TIM2 CH1 (STM32)


f_pwm = f_timer_clk / ((PSC+1) * (ARR+1))
duty = (CCR / (ARR+1)) * 100%

c
RCC->APB1ENR |= RCC_APB1ENR_TIM2EN;

TIM2->PSC  = 83;      /* 84MHz / 84 = 1 MHz tick */
TIM2->ARR  = 999;     /* 1 kHz PWM */
TIM2->CCR1 = 500;     /* 50% duty */
TIM2->CCMR1 |= (6U << TIM_CCMR1_OC1M_Pos);  /* PWM mode 1 */
TIM2->CCER  |= TIM_CCER_CC1E;
TIM2->CR1   |= TIM_CR1_CEN;

GPIO: PA0 AF1 TIM2_CH1.

2. SysTick tick

c
volatile uint32_t tick_ms;

void SysTick_Handler(void) {
    tick_ms++;
}

void systick_init(uint32_t hz) {
    SysTick_Config(SystemCoreClock / hz);
}

3. Input capture

Configure channel in CCMR as input, set CCER polarity, read CCR on interrupt when edge captured.

4. Agent usage


/timers-pwm-baremetal 1 kHz 25% duty PWM on TIM2 channel 1

Common Problems

Symptom	Cause	Fix
Wrong frequency	APB timer clock doubling	Check RM timer clock x2 rule
No PWM output	CCER/CCMR not enabled	Enable channel output
Jittery tick	SysTick overridden	One owner for SysTick

Frequently asked questions

What does the Timers Pwm Baremetal AI skill do?

Why use Timers Pwm Baremetal on TypingMind?

Because you install it once and use it with any model. Timers Pwm Baremetal is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Timers Pwm Baremetal in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/mohitmishra786/low-level-dev-skills/tree/main/skills/baremetal/timers-pwm-baremetal. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Timers Pwm Baremetal?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Timers Pwm Baremetal?

As many as you like. As long as a model supports skills, you can use Timers Pwm Baremetal with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Timers Pwm Baremetal AI skill free?

Yes. It is published on GitHub by mohitmishra786 under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
