+```
+
+### Monitor
+
+```bash
+# For CAN proxy version
+pio run -e esp32-proxy --target monitor
+
+# For OBD-II emulator version
+pio run -e esp32-emulator --target monitor
+```
+
+## Configuration
+
+### CAN Bus Settings
+
+Both CAN buses are configured for:
+
+- **Baud Rate**: 500 kbps
+- **Clock Frequency**: 8 MHz
+- **Frame Buffer Size**: 32 frames per bus
+- **SPI Configuration**:
+  - **SCK Pin**: GPIO18
+  - **MISO Pin**: GPIO19
+  - **MOSI Pin**: GPIO23
+  - **SPI Frequency**: 1 MHz
+  - **SPI Bit Order**: MSBFIRST
+  - **SPI Mode**: SPI_MODE0
+
+### Monitoring
+
+Connect to the UDP broadcast to monitor system status:
+
+```bash
+tcpdump -ni wlp1s0 port 23000 and not src 192.168.101.255 -A
+```
+
+Or access the web interface at `http://[ESP32_IP]:23002` for real-time debug output.
+
+## Status Output
+
+The system provides comprehensive status information via UDP broadcast:
+
+```
+=== OBD-II CAN Proxy Status ===
+Frames buffered: 0, Processed frames: 5, Dropped frames: 0
+=== CAN Proxy Statistics ===
+CAN1 Received: 15
+CAN2 Received: 12
+Forwarded CAN1->CAN2: 15
+Forwarded CAN2->CAN1: 12
+Dropped CAN1: 0
+Dropped CAN2: 0
+Errors CAN1: 0
+Errors CAN2: 0
+CAN1 Buffer: 0/32
+CAN2 Buffer: 0/32
+===========================
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### CAN Bus Not Initializing
+
+- Check SPI connections (MOSI, MISO, SCK)
+- Verify CS and INT pin connections
+- Check power supply to MCP2515 boards
+- Ensure CS pins are pulled HIGH during idle (add `pinMode(cs_pin, INPUT_PULLUP)`)
+
+#### Frame Dropping
+
+- Increase frame buffer size if needed
+- Check CAN bus termination
+- Verify baud rate matches target devices
+- Monitor interrupt frequency
+
+#### WiFi Connection Issues
+
+- Verify SSID and password in code (currently hardcoded to "Netdrop")
+- Check WiFi signal strength
+- Ensure network allows UDP broadcast
+
+### Debug Commands
+
+The system provides several debug features:
+
+- **Register dumping**: `can_proxy.dumpRegisters(stream)`
+- **Statistics reset**: `can_proxy.resetStats()`
+- **Frame data logging**: Automatic via UDP broadcast
+- **Web interface**: Access at `http://[ESP32_IP]:23002`
+
+## Performance Considerations
+
+### Frame Latency
+
+- **Typical latency**: < 1ms for frame forwarding
+- **Buffer overflow**: Monitored via statistics
+- **Interrupt handling**: Optimized for minimal latency
+
+### Memory Usage
+
+- **Frame buffers**: ~2KB total (32 frames × 2 buses)
+- **UDP buffers**: 256 bytes
+- **Web server buffer**: 4KB
+- **Stack usage**: Minimal due to interrupt optimization
+
+### Power Consumption
+
+- **ESP32**: ~150mA at 160MHz
+- **MCP2515 boards**: ~50mA each
+- **Total**: ~250mA typical
+
+## Advanced Configuration
+
+### Custom Baud Rates
+
+Modify the `CANConfig` structures in `src/OBD2Proxy.cpp`:
+
+```cpp
+CANConfig can1_config = {
+    .instance_id = 0,
+    .cs_pin = 5,
+    .irq_pin = 4,
+    .baud_rate = 250000,  // Custom baud rate
+    .clock_frequency = 8000000,
+    .name = "CAN1",
+    .spi_sck_pin = 18,    // SPI clock pin
+    .spi_miso_pin = 19,   // SPI MISO pin
+    .spi_mosi_pin = 23,   // SPI MOSI pin
+    .spi_frequency = 1000000,  // SPI frequency in Hz
+    .spi_bit_order = MSBFIRST, // SPI bit order
+    .spi_mode = SPI_MODE0      // SPI mode
+};
+```
+
+### Buffer Sizes
+
+Adjust frame buffer sizes in the CANStream library configuration.
+
+### GPIO Pins
+
+Change pin assignments as needed (ensure no conflicts):
+
+```cpp
+CANConfig can2_config = {
+    .instance_id = 1,
+    .cs_pin = 17,   // Alternative CS pin
+    .irq_pin = 18,  // Alternative INT pin
+    .spi_sck_pin = 18,    // SPI clock pin
+    .spi_miso_pin = 19,   // SPI MISO pin
+    .spi_mosi_pin = 23,   // SPI MOSI pin
+    .spi_frequency = 1000000,  // SPI frequency in Hz
+    .spi_bit_order = MSBFIRST, // SPI bit order
+    .spi_mode = SPI_MODE0,     // SPI mode
+    // ... other settings
+};
+```
+
+## Single CAN Mode (OBD-II Emulator)
+
+### Hardware Setup
+- Connect **1x MCP2515 breakout board** to the ESP32
+- **CAN**: GPIO5 (CS), GPIO4 (INT) - OBD-II interface
+- **SPI**: GPIO23 (MOSI), GPIO19 (MISO), GPIO18 (SCK)
+
+### Build and Flash
+```bash
+# Build single CAN version
+pio run -e esp32-emulator
+
+# Upload to ESP32
+pio run -e esp32-emulator --target upload
+
+# Monitor output
+pio run -e esp32-emulator --target monitor

+ArduinoJson: change log
+=======================
+
+v7.4.1 (2025-04-11)
+------
+
+* Fix crash with tiny Flash strings (issue #2170)
+
+v7.4.0 (2025-04-09)
+------
+
+* Optimize storage of tiny strings (up to 3 characters)
+* Fix support for `const char[]` (issue #2166)
+
+v7.3.1 (2025-02-27)
+------
+
+* Fix conversion from static string to number
+* Slightly reduce code size
+
+v7.3.0 (2024-12-29)
+------
+
+* Fix support for NUL characters in `deserializeJson()`
+* Make `ElementProxy` and `MemberProxy` non-copyable
+* Change string copy policy: only string literal are stored by pointer
+* `JsonString` is now stored by copy, unless specified otherwise
+* Replace undocumented `JsonString::Ownership` with `bool`
+* Rename undocumented `JsonString::isLinked()` to `isStatic()`
+* Move public facing SFINAEs to template declarations
+
+> ### BREAKING CHANGES
+>
+> In previous versions, `MemberProxy` (the class returned by `operator[]`) could lead to dangling pointers when used with a temporary string.
+> To prevent this issue, `MemberProxy` and `ElementProxy` are now non-copyable.
+>
+> Your code is likely to be affected if you use `auto` to store the result of `operator[]`. For example, the following line won't compile anymore:
+>
+> ```cpp
+> auto value = doc["key"];
+> ```
+>
+> To fix the issue, you must append either `.as<T>()` or `.to<T>()`, depending on the situation.
+>
+> For example, if you are extracting values from a JSON document, you should update like this:
+>
+> ```diff
+> - auto config = doc["config"];
+> + auto config = doc["config"].as<JsonObject>();
+> const char* name = config["name"];
+> ```
+>
+> However, if you are building a JSON document, you should update like this:
+>
+> ```diff
+> - auto config = doc["config"];
+> + auto config = doc["config"].to<JsonObject>();
+> config["name"] = "ArduinoJson";
+> ```
+
+v7.2.1 (2024-11-15)
+------
+
+* Forbid `deserializeJson(JsonArray|JsonObject, ...)` (issue #2135)
+* Fix VLA support in `JsonDocument::set()`
+* Fix `operator[](variant)` ignoring NUL characters
+
+v7.2.0 (2024-09-18)
+------
+
+* Store object members with two slots: one for the key and one for the value
+* Store 64-bit numbers (`double` and `long long`) in an additional slot
+* Reduce the slot size (see table below)
+* Improve message when user forgets third arg of `serializeJson()` et al.
+* Set `ARDUINOJSON_USE_DOUBLE` to `0` by default on 8-bit architectures
+* Deprecate `containsKey()` in favor of `doc["key"].is<T>()`
+* Add support for escape sequence `\'` (issue #2124)
+
+| Architecture | before   | after    |
+|--------------|----------|----------|
+| 8-bit        | 8 bytes  | 6 bytes  |
+| 32-bit       | 16 bytes | 8 bytes  |
+| 64-bit       | 24 bytes | 16 bytes |
+
+> ### BREAKING CHANGES
+>
+> After being on the death row for years, the `containsKey()` method has finally been deprecated.
+> You should replace `doc.containsKey("key")` with `doc["key"].is<T>()`, which not only checks that the key exists but also that the value is of the expected type.
+>
+> ```cpp
+> // Before
+> if (doc.containsKey("value")) {
+>   int value = doc["value"];
+>   // ...
+> }
+>
+> // After
+> if (doc["value"].is<int>()) {
+>   int value = doc["value"];
+>   // ...
+> }
+> ```
+
+v7.1.0 (2024-06-27)
+------
+
+* Add `ARDUINOJSON_STRING_LENGTH_SIZE` to the namespace name
+* Add support for MsgPack binary (PR #2078 by @Sanae6)
+* Add support for MsgPack extension
+* Make string support even more generic (PR #2084 by @d-a-v)
+* Optimize `deserializeMsgPack()`
+* Allow using a `JsonVariant` as a key or index (issue #2080)
+  Note: works only for reading, not for writing
+* Support `ElementProxy` and `MemberProxy` in `JsonDocument`'s constructor
+* Don't add partial objects when allocation fails (issue #2081)
+* Read MsgPack's 64-bit integers even if `ARDUINOJSON_USE_LONG_LONG` is `0`
+  (they are set to `null` if they don't fit in a `long`)
+
+v7.0.4 (2024-03-12)
+------
+
+* Make `JSON_STRING_SIZE(N)` return `N+1` to fix third-party code (issue #2054)
+
+v7.0.3 (2024-02-05)
+------
+
+* Improve error messages when using `char` or `char*` (issue #2043)
+* Reduce stack consumption (issue #2046)
+* Fix compatibility with GCC 4.8 (issue #2045)
+
+v7.0.2 (2024-01-19)
+------
+
+* Fix assertion `poolIndex < count_` after `JsonDocument::clear()` (issue #2034)
+
+v7.0.1 (2024-01-10)
+------
+
+* Fix "no matching function" with `JsonObjectConst::operator[]` (issue #2019)
+* Remove unused files in the PlatformIO package
+* Fix `volatile bool` serialized as `1` or `0` instead of `true` or `false` (issue #2029)
+
+v7.0.0 (2024-01-03)
+------
+
+* Remove `BasicJsonDocument`
+* Remove `StaticJsonDocument`
+* Add abstract `Allocator` class
+* Merge `DynamicJsonDocument` with `JsonDocument`
+* Remove `JSON_ARRAY_SIZE()`, `JSON_OBJECT_SIZE()`, and `JSON_STRING_SIZE()`
+* Remove `ARDUINOJSON_ENABLE_STRING_DEDUPLICATION` (string deduplication cannot be disabled anymore)
+* Remove `JsonDocument::capacity()`
+* Store the strings in the heap
+* Reference-count shared strings
+* Always store `serialized("string")` by copy (#1915)
+* Remove the zero-copy mode of `deserializeJson()` and `deserializeMsgPack()`
+* Fix double lookup in `to<JsonVariant>()`
+* Fix double call to `size()` in `serializeMsgPack()`
+* Include `ARDUINOJSON_SLOT_OFFSET_SIZE` in the namespace name
+* Remove `JsonVariant::shallowCopy()`
+* `JsonDocument`'s capacity grows as needed, no need to pass it to the constructor anymore
+* `JsonDocument`'s allocator is not monotonic anymore, removed values get recycled
+* Show a link to the documentation when user passes an unsupported input type
+* Remove `JsonDocument::memoryUsage()`
+* Remove `JsonDocument::garbageCollect()`
+* Add `deserializeJson(JsonVariant, ...)` and `deserializeMsgPack(JsonVariant, ...)` (#1226)
+* Call `shrinkToFit()` in `deserializeJson()` and `deserializeMsgPack()`
+* `serializeJson()` and `serializeMsgPack()` replace the content of `std::string` and `String` instead of appending to it
+* Replace `add()` with `add<T>()` (`add(T)` is still supported)
+* Remove `createNestedArray()` and `createNestedObject()` (use `to<JsonArray>()` and `to<JsonObject>()` instead)
+
+> ### BREAKING CHANGES
+>
+> As every major release, ArduinoJson 7 introduces several breaking changes.
+> I added some stubs so that most existing programs should compile, but I highty recommend you upgrade your code.
+>
+> #### `JsonDocument`
+> 
+> In ArduinoJson 6, you could allocate the memory pool on the stack (with `StaticJsonDocument`) or in the heap (with `DynamicJsonDocument`).  
+> In ArduinoJson 7, the memory pool is always allocated in the heap, so `StaticJsonDocument` and `DynamicJsonDocument` have been merged into `JsonDocument`.
+>
+> In ArduinoJson 6, `JsonDocument` had a fixed capacity; in ArduinoJson 7, it has an elastic capacity that grows as needed.
+> Therefore, you don't need to specify the capacity anymore, so the macros `JSON_ARRAY_SIZE()`, `JSON_OBJECT_SIZE()`, and `JSON_STRING_SIZE()` have been removed.
+>
+> ```c++
+> // ArduinoJson 6
+> StaticJsonDocument<256> doc;
+> // or
+> DynamicJsonDocument doc(256);
+> 
+> // ArduinoJson 7
+> JsonDocument doc;
+> ```
+>
+> In ArduinoJson 7, `JsonDocument` reuses released memory, so `garbageCollect()` has been removed.  
+> `shrinkToFit()` is still available and releases the over-allocated memory.
+>
+> Due to a change in the implementation, it's not possible to store a pointer to a variant from another `JsonDocument`, so `shallowCopy()` has been removed.
+> 
+> In ArduinoJson 6, the meaning of `memoryUsage()` was clear: it returned the number of bytes used in the memory pool.  
+> In ArduinoJson 7, the meaning of `memoryUsage()` would be ambiguous, so it has been removed.
+>
+> #### Custom allocators
+>
+> In ArduinoJson 6, you could specify a custom allocator class as a template parameter of `BasicJsonDocument`.  
+> In ArduinoJson 7, you must inherit from `ArduinoJson::Allocator` and pass a pointer to an instance of your class to the constructor of `JsonDocument`.
+>
+> ```c++
+> // ArduinoJson 6
+> class MyAllocator {
+>   // ...
+> };
+> BasicJsonDocument<MyAllocator> doc(256);
+>
+> // ArduinoJson 7
+> class MyAllocator : public ArduinoJson::Allocator {
+>   // ...
+> };
+> MyAllocator myAllocator;
+> JsonDocument doc(&myAllocator);
+> ```
+>
+> #### `createNestedArray()` and `createNestedObject()`
+>
+> In ArduinoJson 6, you could create a nested array or object with `createNestedArray()` and `createNestedObject()`.  
+> In ArduinoJson 7, you must use `add<T>()` or `to<T>()` instead.
+>
+> For example, to create `[[],{}]`, you would write:
+>
+> ```c++
+> // ArduinoJson 6
+> arr.createNestedArray();
+> arr.createNestedObject();
+>
+> // ArduinoJson 7
+> arr.add<JsonArray>();
+> arr.add<JsonObject>();
+> ```
+>
+> And to create `{"array":[],"object":{}}`, you would write:
+>
+> ```c++
+> // ArduinoJson 6
+> obj.createNestedArray("array");
+> obj.createNestedObject("object");
+>
+> // ArduinoJson 7
+> obj["array"].to<JsonArray>();
+> obj["object"].to<JsonObject>();
+> ```

+## Quickstart
+
+### Deserialization
+
+Here is a program that parses a JSON document with ArduinoJson.
+
+```c++
+const char* json = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
+
+JsonDocument doc;
+deserializeJson(doc, json);
+
+const char* sensor = doc["sensor"];
+long time          = doc["time"];
+double latitude    = doc["data"][0];
+double longitude   = doc["data"][1];
+```
+
+See the [tutorial on arduinojson.org](https://arduinojson.org/v7/doc/deserialization/)
+
+### Serialization
+
+Here is a program that generates a JSON document with ArduinoJson:
+
+```c++
+JsonDocument doc;
+
+doc["sensor"] = "gps";
+doc["time"]   = 1351824120;
+doc["data"][0] = 48.756080;
+doc["data"][1] = 2.302038;
+
+serializeJson(doc, Serial);
+// This prints:
+// {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
+```
+
+See the [tutorial on arduinojson.org](https://arduinojson.org/v7/doc/serialization/)

+If you run a commercial project that embeds ArduinoJson, think about [sponsoring the library's development](https://github.com/sponsors/bblanchon): it ensures the code that your products rely on stays actively maintained. It can also give your project some exposure to the makers' community.
+
+If you are an individual user and want to support the development (or give a sign of appreciation), consider purchasing the book [Mastering ArduinoJson](https://arduinojson.org/book/)&nbsp;❤, or simply [cast a star](https://github.com/bblanchon/ArduinoJson/stargazers)&nbsp;⭐.
