v2.3.7 - Fix swich_pin Typo (2026-02-24)¶

What Changed?¶

This release fixes the swich_pin typo in v2_main.cpp and replaces the local variable with the SWITCH_PIN constant from config.h. No behavior changes; fully backward compatible.

What's New¶

Main Feature: Fix swich_pin Typo and Use SWITCH_PIN Constant¶

What it does:

Removes the local const int swich_pin = 0 variable and replaces its use in attachInterrupt() with the SWITCH_PIN constant defined in config.h. config.h is now the single source of truth for the switch pin number.

Why it matters:

Fixes the swich_pin typo (missing t)
Build-flag overrides (-DSWITCH_PIN=xx) now take effect in v2_main.cpp
Consistent with the project's SSOT pattern for pin constants

Installation¶

Quick Start¶

# Get the release
git checkout v2.3.7

# Build
task v2:build

# Upload
task v2:upload

# Check it works
task monitor

What's Different from the Last Version?¶

🐛 Fixed¶

v2_main.cpp: removed const int swich_pin = 0 local variable (typo: missing t)
v2_main.cpp: replaced swich_pin with SWITCH_PIN from config.h in attachInterrupt()

Is It Safe to Upgrade?¶

Backward Compatible: Yes

SWITCH_PIN defaults to GPIO0 (same value as the removed variable)
No change in interrupt behavior or runtime output

Tests Passed¶

✅ Builds without errors
