Detailed Description

Builder / installer-friendly GPIO self-test helpers for ESP32-based LCC Fusion cards.

This header defines a small utility class, PstTestPins, that runs quick sanity checks on pins without requiring fixtures. It prints clear, non-jargony messages via a global g_serialIO.

Typical usage:

PstTestPins pst;
pst.testPin(I2C_SDA_PIN, PstTestPins::Type::I2C_SDA, "I2C_SDA");
pst.testPin(I2C_SCL_PIN, PstTestPins::Type::I2C_SCL, "I2C_SCL");

Notes

• Designed around ESP32 (DevKit-C class). Input-only pins (GPIO 34-39) are handled gracefully.
• Tests avoid electrical jargon like "rail”; messages target end users (builders / installers).

Warning

This file expects a global/static SerialIO-like object named g_serialIO that provides print(...) and sprintf(fmt, ...) methods compatible with Arduino Print.
