If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that Work shall terminate as of the date such litigation is filed.

-
-     You may add Your own copyright statement to Your modifications and may provide additional or different license terms and conditions for use, reproduction, or distribution of Your modifications, or for any such Derivative Works as a whole, provided Your use, reproduction, and distribution of the Work otherwise complies with the conditions stated in this License.

-
-9. Accepting Warranty or Additional Liability. While redistributing the Work or Derivative Works thereof, You may choose to offer, and charge a fee for, acceptance of support, warranty, indemnity, or other liability obligations and/or rights consistent with this License. However, in accepting such obligations, You may act only on Your own behalf and on Your sole responsibility, not on behalf of any other Contributor, and only if You agree to indemnify, defend, and hold each Contributor harmless for any liability incurred by, or claims asserted against, such Contributor by reason of your accepting any such warranty or additional liability.

-## TODO
-
- Existing but not implemented commands: 0x19, 0x25, 0x28, 0x2E, 0x50, 0x51, 0x52, 0x53
- Commands 0x2E, 0x50, 0x51, 0x52, 0x53 seem to be used for firmware update: DO NOT SEND THEM WITHOUT KNOWLEDGE - RISK OF DEVICE BRICK (I brick my device)
- Commands: 0x19, 0x24, 0x28 are triggered by upload preset
- Identify: 0x2C parameters
- Implement: if 2 DSP with same ip they need to share same socket since dsp dont accept multiples connections
- In unlock check if first byte is device id
- This library allows to send commands even if dsp is locked
- Convert back data as in 0x38 to display real value
- Figure out Meter level encoding
- Full test of client (Improve existing one)
- Write correct readme.md
-
-Rust library for remote LAN control of Thomann DSP408 digital signal processors.
-
-`dsp_thomann` provides a high-level Rust API to connect, configure and monitor a DSP408 device over TCP/IP.
-
-## Features
-
- TCP LAN communication with DSP408
- Automatic handshake and connection management
- Device state synchronization
- Preset management
- Channel routing
- Input/output processing control:
-  - Gain
-  - Mute
-  - Phase inversion
-  - Delay
-  - PEQ
-  - GEQ
-  - Crossover filters
-  - Compressor
-  - Limiter
-  - Gate
- Matrix routing and channel linking
- Level meter reading
- Device locking/unlocking
- Strong Rust type safety
- Protocol frame decoding and validation
-
---
-
-## Installation
-
-Add the crate to your `Cargo.toml`:
-
-```toml
-[dependencies]
-dsp_thomann = "0.1"
-```
-
---
-
-## Quick Start
-
-```rust
-use std::net::IpAddr;
-use dsp_thomann::dsp408::{DSP408, types};
-
-fn main() -> Result<(), Box<dyn std::error::Error>> {
-
-    let host: IpAddr = "192.168.49.30".parse()?;
-
-    let mut dsp = DSP408::new(
-        host,
-        9761,
-        1
-    )?;
-
-    dsp.connect()?;
-
-    println!("Connected!");
-
-    dsp.set_mute(
-        types::Channel::Input(types::InputChannel::InA),
-        true
-    )?;
-
-    println!("{:#?}", dsp.state()?);
-
-    dsp.disconnect();
-
-    Ok(())
-}
-```
-
---
-
-# Connection
-
-A DSP device is identified by:
-
-| Parameter | Description |
-|---|---|
-| Host | DSP IP address |
-| Port | TCP control port |
-| Device ID | DSP device identifier |
-
-Example:
-
-```rust
-let mut dsp = DSP408::new(
-    "192.168.49.30".parse()?,
-    9761,
-    1
-)?;
-```
-
-The library performs:
-
- TCP connection
- DSP handshake
- Device information retrieval
- Preset state loading
- Configuration synchronization
-
---
-
-# Device State
-
-After connection:
-
-```rust
-let state = dsp.state()?;
-```
-
-The state contains:
-
- Device name
- Lock status
- Preset bank
- Current DSP configuration
-
-Including:
-
- Input channels
- Output channels
- Routing
- EQ
- Dynamics
- Delay
- Crossover configuration
-
---
-
-# Channel Control
-
-Channels are strongly typed:
-
-```rust
-types::Channel::Input(
-    types::InputChannel::InA
-)
-```
-
-```rust
-types::Channel::Output(
-    types::OutputChannel::Out1
-)
-```
-
-## Available Channels
-
-### Inputs
-
- InA
- InB
- InC
- InD
-
-### Outputs
-
- Out1
- Out2
- Out3
- Out4
- Out5
- Out6
- Out7
- Out8
-
---
-
-# Audio Processing
-
-## Gain
-
-```rust
-dsp.set_channel_gain(
-    types::Channel::Output(types::OutputChannel::Out1),
-    -3.0
-)?;
-```
-
---
-
-## Delay
-
-```rust
-dsp.set_channel_delay(
-    channel,
-    2.5,
-    types::DelayUnit::Millisecond
-)?;
-```
-
---
-
-## PEQ
-
-```rust
-dsp.set_peq_band(
-    channel,
-    types::PEQBand::B1,
-    3.0,
-    1000.0,
-    0.7,
-    types::PEQFilter::Peak,
-    false
-)?;
-```
-
---
-
-## Compressor
-
-```rust
-dsp.set_compressor(
-    types::OutputChannel::Out1,
-    types::Ratio::Ratio1_4,
-    10,
-    100,
-    3,
-    -10.0
-)?;
-```
-
---
-
-# Presets
-
-## Recall a preset
-
-```rust
-dsp.recall_preset(1)?;
-```
-
-## Store current configuration
-
-```rust
-dsp.store_current_configuration(
-    2,
-    false
-)?;
-```
-
-## Rename current preset
-
-```rust
-dsp.set_current_preset_name(
-    "Live Show"
-)?;
-```
-
---
-
-# Routing
-
-## Matrix routing
-
-```rust
-dsp.set_matrix_routing(
-    types::OutputChannel::Out1,
-    vec![
-        types::InputChannel::InA,
-        types::InputChannel::InB,
-    ],
-)?;
-```
-
-## Link channels
-
-```rust
-dsp.link_channels(
-    source,
-    vec![destination]
-)?;
-```
-
---
-
-# Metering
-
-Read signal levels:
-
-```rust
-let meters = dsp.get_meter_levels()?;
-
-println!("{:?}", meters.levels);
-```
-
---
-
-# Error Handling
-
-All operations return:
-
-```rust
-Result<T, DSPError>
-```
-
-Possible errors include:
-
- Connection failure
- Timeout
- Invalid parameters
- Protocol errors
- Invalid responses
- Encoding/decoding failures
-
-Example:
-
-```rust
-match dsp.connect() {
-    Ok(_) => println!("Connected"),
-    Err(e) => println!("Error: {}", e),
-}
-```
-
---
-
-# Thread Safety
-
-The library internally protects socket access with a mutex.
-
- Only one command is transmitted at a time per DSP408 instance.
- Multiple DSP devices can be controlled simultaneously.
-
---
