# SLICEDBCommands Module Documentation

## 1. Purpose

This module implements a command pattern architecture for communicating with SLICE DB hardware devices. It provides a hierarchical class structure for constructing, sending, and receiving command packets over a communication interface (`ICommunication`). The module handles various device operations including power management (voltage/current queries and configuration), network settings (IP, MAC, netmask), device arming/disarming for data acquisition, and device information queries (serial number, firmware versions, time synchronization). Commands are organized by functional category, each inheriting from a category-specific abstract base class that itself inherits from `CommandBase`.

## 3. Invariants

1. **Sequence Number Uniqueness:** `CommandPacket.GlobalSequenceNumber` is incremented atomically under `GlobalSequenceNumberLock` to ensure thread-safe unique sequence numbers across all command packets.

2. **Command Type Assignment:** All concrete command classes must set `command.Type` to the appropriate `CommandPacket.CommandType` value in their constructor (e.g., `PowerCommands` sets `CommandType.Power`).

3. **Abstract Command Property:** All concrete command classes inheriting from category base classes (`PowerCommands`, `ArmCommands`, `NetworkCommands`, `InformationCommands`) must override the abstract `_Command` property.

4. **Parameter Buffer Allocation:** Setters that modify command parameters must allocate the `command.Parameter` byte array before calling `command.SetParameter()`.

5. **Protocol Version Enforcement:** Certain commands (e.g., `QueryBatteryVoltageMV`, `Arm`, `Disarm`) set `MinimumProtocolVersion` via `sock.GetMinProto()` to ensure firmware compatibility.

6. **Time Representation:** `QueryTime` and `SetTime` use Unix epoch (1970-01-01) with seconds and microseconds components stored as `UInt32` values.

## 5. Gotchas

1. **Duplicate Enum Values in PowerCommands.Commands:** The `Commands` enum in `PowerCommands.cs` contains duplicate values:
   - `QuerySliceBusInputCurrentOvercurrentLimitMA = 0x17` and `QueryBatteryChargeCurrentOvercurrentLimitMA = 0x17`
   - `SetSliceBusInputCurrentOvercurrentLimitMA = 0x18` and `SetBatteryChargeCurrentOvercurrentLimitMA = 0x18`
   - `QuerySliceBusInputCurrentOvercurrentCount = 0x19` and `QueryBatteryChargeCurrentOvercurrentCount = 0x19`
   - `SetSliceBusInputCurrentOvercurrentCount = 0x1A` and `SetBatteryChargeCurrentOvercurrentCount = 0x1A`
   
   This appears to be a bug or copy-paste error. No concrete implementations exist for these commands in the provided source.

2. **Commented-Out Implementation Classes:** `CalibrationCommands.cs` contains commented-out stub classes (`QueryOffset`, `SetOffset`, `QueryMultiplier`, `SetMultiplier`), suggesting incomplete implementation.

3. **Misleading XML Documentation:** Several XML comments are inaccurate:
   - `SetRecordingMode.Value`: Comment says "The current Dat0 reg of the SLICE DB" but property is `byte` for recording mode.
   - `SetPostTriggerSec.Value`: Same incorrect comment about "Dat0 reg".
   - `SetONOverride.Value`: Comment says "The current StatusLED reg of the SLICE DB" but property is `bool`.
   - `SetCalibrationDaysSince1970_01_01.CalibrationDaysSince1970_01_01`: Comment says "The serial number of the SLICE DB".
   - `QueryProtocolVersion.ResponseToString`: Formats string as "Firmware Version" instead of "Protocol Version".
   - `QueryKernelVersion.ResponseToString` and `QueryMSPFirmwareVersion.ResponseToString`: Both format as "Firmware Version" without distinguishing kernel vs MSP.

4. **Typo in Enum Value:** `SetBattteryVoltageOvervoltageLimitMV` has three 't's in "Batttery" (value `0x14`).

5. **Inconsistent Status Checking:** Some `WholePackage()` implementations check `response.Status != StatusNoError` and return early, while others check `response.Status == StatusNoError` before processing. The behavior differs slightly in whether the output property gets set to a default value.
