Testing the Markdown Renderer

This is a long test note with a bit of everything — headings, lists, a table, code, and an image — so you can confirm the Write/Preview tabs render correctly.

Why this matters

Before a board ships, it goes through three stages:

1. Bench validation
2. Field pilot
3. Production sign-off

Common failure modes:

• Power sequencing bugs that only show up on brownout
• Firmware that assumes a network connection always exists
• Enclosures rated for a lab, not a rooftop in July

"The spec sheet is a hypothesis. The field is the experiment."

Code

uint16_t read_sensor(uint8_t retries) {
    uint16_t value = 0;
    while (retries--) {
        if (adc_read(&value) == ADC_OK) return value;
        delay_ms(50);
    }
    return SENSOR_READ_FAILED;
}

Inline code looks like this: GPIOA->MODER.

Formatting

Some italic, some bold, some struck-through text, and a link.

• Renders tables
• Needs a real photo
