T210 Connect — Serial Port Temperature/Power Monitor

Desktop monitoring application for ABToolkit T210 solder station (STM32F103CB/C8T6).
Real-time temperature and power tracking via serial communication with dual-axis charting and responsive UI.

---

🎯 Features

• Real-time Monitoring: Live temperature (0-500°C) and power (0-100%)
• Auto Baudrate Detection: Automatic serial baud detection (9600 → 230400)
• Dual-Axis Chart: Temperature + Power with 600-point rolling buffer
• Responsive UI: Optimized for floating window and fullscreen
• Status Mapping: Condition code mapping with color indicators
• Windows Desktop App: Packaged with Tauri (NSIS target)

📊 Telemetry Data Format (MCU → App)

The app reads CSV telemetry from serial stream.

Base order (new fields appended at the end)

actualTemp,setpoint,power,status,buzzer,standbyState,standbyTimer

Field definitions

Field	Type	Normal Range	Unit	Notes
actualTemp	float	0-500	°C	Actual measured temperature
setpoint	float	0-500	°C	Target setpoint (shown in gauge)
power	float	0-100	%	Heater power / PWM duty
status	int	0,1,2,10,11,12	—	Device condition code
buzzer	int	0/1	—	Buzzer state
standbyState	int	0/1	—	Standby state
standbyTimer	int	0-300	s	Standby countdown timer

---

✅ Partial Payload Compatibility

Telemetry parser is backward-compatible with older firmware payloads.

• If MCU sends fewer fields (e.g. 6 fields), app still parses available values.
• Missing trailing fields are treated as null.
• UI renders missing values as placeholder (-- / -- s) instead of crashing.
• Chart updates only when required values (actualTemp, power) are valid numbers.

This allows schema expansion by appending new fields at the end without breaking older MCU builds.

🧭 Status Code Mapping

Code	Condition	UI Display	Meaning
0	CONDITION_SLEEP	Sleep	Heater off / sleep mode
1	CONDITION_STANDBY	Standby	Waiting standby timeout
2	CONDITION_RUN	Running	Normal heating mode
10	CONDITION_ERR_SENSOR	Error: Sensor	Sensor reading invalid/fault
11	CONDITION_ERR_OVERHEAT	Error: Overheat	Temperature too high (>500°C)
12	CONDITION_ERR_NO_HEAT	Error: No Heat	Heater not increasing temperature

🚀 Getting Started

Prerequisites

• Node.js 18+
• Rust stable toolchain
• Windows environment (current package target: NSIS)

Development

npm install
npm run tauri dev

Type check

npm run check

Production build

npm run tauri build

Output artifacts (located in src-tauri/target/release/bundle/):

• nsis/T210 Connect_{version}_x64-setup.exe — Windows installer
• t210-connect.exe — Standalone executable

Note: {version} is taken from package.json at build time.

🔄 Version Management

The single source of truth for the app version is package.json.

How to update the version

# Automatic — updates all files:
npm version patch   # 0.1.0 → 0.1.1
npm version minor   # 0.1.0 → 0.2.0
npm version major   # 0.1.0 → 1.0.0

# Or specify an exact version:
npm version 0.2.0

After npm version finishes, the postversion hook automatically runs node scripts/sync-version.js, which syncs the version to:

File	Role
package.json	Single source of truth
src-tauri/tauri.conf.json	Tauri app config (runtime version)
src-tauri/Cargo.toml	Rust crate version

Manual sync

npm run version:sync
