+# Changelog

+---

+### Added
+- Protocol name allowlist filter: in Receiver Config, a new "Proto Filter"
+  field accepts a comma-separated list of protocol names (e.g. "Ford V2,VAG").
+  When set, the receiver ignores all decoded signals that are not in the list,
+  reducing RAM usage and increasing the chance of capturing the target protocol.
+  Leave empty to disable (default behavior, all protocols accepted).
+  Setting is persisted in last_subghz.settings under the ProtocolFilter key.

+### Changed
+- Protocol Filter: replaced free-text input with a dedicated protocol list
+  scene (Proto Filter in Receiver Config). All registered protocols are shown
+  as toggleable items (--- / ONLY). Selecting one or more protocols restricts
+  the receiver to only show those; leaving all as --- disables the filter.
+  The active count is shown inline in Receiver Config ("N set" or "All").
+  Filter is persisted across sessions and cleared by Reset to default.

-LF Analyzer -- Decodes captures from the LF Sniffer FAP
-=========================================================
-Analyzes edge timings captured by the Flipper Zero FAP and determines:
-  - Modulation type (ASK/FSK/PSK)
-  - Encoding (Manchester, Biphase, NRZ, PWM)
-  - Bit period and carrier frequency
-  - Decoded bit stream
-  - Likely protocol (Hitag2, Hitag S, EM4100, etc.)
-  - KeylessGO challenge candidate if applicable
-
-Usage:
-  python3 lf_analyze.py capture_0000.csv
-  python3 lf_analyze.py capture_0000.csv --verbose
-  python3 lf_analyze.py capture_0000.csv --protocol hitag2

+# Changelog
+
+All notable changes to the 24cxxprog EEPROM Programmer application will be documented in this file.
+
+## [2.0.0] - 2026-03-11
+
+### 🚀 Major Features Added
+
+#### Dynamic Memory Support for All 24Cxx Chips
+- **Full chip type support**: Added complete support for all EEPROM sizes from 24C01 (128B) to 24C512 (64KB)
+- **Dynamic buffer allocation**: Memory buffers now automatically resize based on selected chip type
+- **Configurable in Settings**: Users can now select chip type in Settings menu, and all operations adapt automatically
+
+### ✨ Enhancements
+
+#### Memory Management
+- Replaced fixed 256-byte buffers with dynamic allocation:
+  - `memory_data` - dynamically allocated based on chip size
+  - `file_data` - dynamically allocated based on chip size  
+  - `verify_buffer` - dynamically allocated based on chip size
+- Added `get_eeprom_size()` helper function returning size in bytes for each chip type
+- Added `reallocate_buffers()` function for automatic buffer reallocation on chip type change
+- Memory size tracked in `memory_size` field (32-bit for chips up to 64KB)
+
+#### Read/Write/Erase Operations
+- **Read operation**: Now reads entire EEPROM regardless of size (128B to 64KB)
+- **Write operation**: Supports writing to full address range of selected chip
+- **Erase operation**: Clears entire memory of selected chip type
+- **File operations**: Binary dumps now save/load full chip capacity
+
+#### User Interface Improvements
+- Address display format adapts to memory size:
+  - Small chips (≤256B): `0x00` format
+  - Large chips (>256B): `0000` hex format (4 digits)
+- Progress indicators updated for all memory sizes
+- Navigation (Up/Down) works across entire address range
+- File size display shows actual chip capacity
+
+#### File Naming
+- Filename generation now includes all chip types:
+  - Examples: `24C01_2026-03-11_10-30.bin`, `24C256_2026-03-11_10-30.bin`
+- Automatic timestamp-based naming for all chip variants
+
+### 🔧 Technical Changes
+
+#### Type Updates
+- Changed address/size types from `uint8_t` to `uint32_t` for large memory support:
+  - `current_address`: now `uint32_t`
+  - `read_total_bytes`: now `uint32_t`
+  - `write_total_bytes_async`: now `uint32_t`
+  - `verify_total_bytes`: now `uint32_t`
+  - `erase_current_addr`: now `uint32_t`
+  - `progress_value`: now `uint32_t`
+  - `file_size`: now `uint32_t`
+
+#### Format Specifiers
+- Updated all `printf`/`snprintf` calls to use correct format for `uint32_t`:
+  - Changed `%d` to `%lu` for unsigned long
+  - Changed `%X` to `%lX` for hex unsigned long
+
+#### Memory Safety
+- Added proper memory initialization in `reallocate_buffers()`
+- Added null pointer checks for all dynamically allocated buffers
+- Proper cleanup in `eeprom_app_free()` - all buffers freed correctly
+
+### 🐛 Bug Fixes
+- Fixed buffer overflow risk in memory operations for larger chips
+- Fixed format specifier warnings causing compilation errors
+- Fixed address boundary checking for chips larger than 256 bytes
+- Fixed progress bar calculations for larger memory sizes
+
+### 🔄 Behavioral Changes
+- Settings → Chip Type now immediately reallocates buffers
+- Current address is reset to 0 if it exceeds new chip size after type change
+- File load operation respects maximum chip capacity (won't load more than chip can hold)
+
+### 📋 Supported Chip Types
+
+Complete support matrix:
+| Chip Type | Size | Status |
+|-----------|------|--------|
+| 24C01 | 128 bytes | ✅ Full Support |
+| 24C02 | 256 bytes | ✅ Full Support |
+| 24C04 | 512 bytes | ✅ Full Support |
+| 24C08 | 1 KB | ✅ Full Support |
+| 24C16 | 2 KB | ✅ Full Support |
+| 24C32 | 4 KB | ✅ Full Support |
+| 24C64 | 8 KB | ✅ Full Support |
+| 24C128 | 16 KB | ✅ Full Support |
+| 24C256 | 32 KB | ✅ Full Support |
+| 24C512 | 64 KB | ✅ Full Support |
+
+### ⚠️ Breaking Changes
+- Binary dump files from previous versions (always 256 bytes) are incompatible with chip-specific sizes
+- Users should re-read and save new dumps after upgrading
+
+---
+
+## [1.0.0] - Previous Version
+
+### Initial Release
+- Basic read/write/erase operations
+- Fixed 256-byte buffer (24C02 only)
+- I2C address configuration
+- File load/save operations
+- Basic hex viewer

+# Chief Cooker
+Your ultimate Flipper Zero restaurant pager tool. Be a _real chief_ of all the restaurants on the food court!
+
+This app supports receiving, decoding, editing and sending restaurant pager signals. 
+
+**Developed & compatible with [Momentum firmware](https://github.com/Next-Flip/Momentum-Firmware).** Other firmwares are most likely not supported (but I've not tried).
+
+## Video demo
+[![Video 1](https://img.youtube.com/vi/iuQSyesS9-o/0.jpg)](https://youtube.com/shorts/iuQSyesS9-o)
+
+More demos:
+- [Video 2](https://youtube.com/shorts/KGDAGblbtFo)
+- [Video 3](https://youtube.com/shorts/QqbfHF-yDiE)
+
+## Disclaimer
+I've built this app for research and learning purposes. But please, don't use it in a way that could hurt anyone or anything.
+
+Use it responsibly, okay?
+
+## [Usage instructions](instructions/instructions.md)
+Please, read the [instructions](instructions/instructions.md) before using the app. It will definitely make your life easier!
+
+## Features
+- **Receive** signals from pager stations
+- Automatically **decode** them and dsiplay station number, pager number and action (Ring/Mute/etc)
+- Manually **change encoding in real-time** to look for the best one if automatically detected encoding is not working
+- **Resend** captured message to specific pager to all at once to **make them all ring**!
+- **Modify** captured signal, e.g. change pager number or action
+- **Save** captured signals (and give each station a name)
+- Create separate **categories** for each food court you are chief on
+- Display signals from saved stations **by ther names** (instead of HEX code) or hide them from list
+- **Send** signals from saved stations at any time, no need to capture it again
+- Of course, suports working with **external CC1101 module** to cover the area of all the pagers on your food court! 
+
+## Supported protocols
+- Princeton
+- SMC5326
+
+## Supported pager encodings
+- Retekess TD157
+- Retekess TD165/T119
+- Retekess TD174
+- L8R / Retekess T111 (not tested)
+- L8S / iBells ZJ-68 (check [source code](app/pager/decoder/L8SDecoder.hpp#L8) for description)
+
+## Contributing
+If you want to add any new pager encoding, please feel free to create PR with it!
+
+Also you can open issue and share with me any captured data (and at least pager number) if you have any and maybe I'll try create a decoder for it
+
+## Building
+If you build the source code just with regular `ufbt` command, the app will probably crash due to out of memory error because your device will have less that 10 kb of free RAM on the "Scan" screen.
+
+This is because after you compile the app with ufbt, the result executable will contain hundreds of sections with very long names like `.fast.rel.text._ZNSt17_Function_handlerIFvmEZN18PagerActionsScreenC4EP9AppConfigSt8functionIFP15StoredPagerDatavEEP12PagerDecoderP13PagerProtocolP12SubGhzModuleEUlmE_E9_M_invokeERKSt9_Any_dataOm`.
+**These names stay in RAM during the execution and consume about 20kb of heap!**
+
+The reason for it is [name mangling](https://en.wikipedia.org/wiki/Name_mangling). Perhaps, the gcc parameter `-fno-mangle` could disable it, but unfortunately, it is not possible to pass any arguments to gcc when you compile app with `ufbt`. 
+Luckily the sections inside the compiled file can be renamed using gcc's `objcopy` tool with `--rename-section` parameter. To automate it, I built a small python script which renames them all and gives them short names like `_s1`, `_s2`, `_s228` etc... 
+
+**Therfore you must use [scripts/build-and-clear.py](scripts/build-and-clear.py) script instead!** It will build, rename sections and upload the fap to flipper.
+
+After building and cleaning your `.fap` with it, you'll get extra +20kb of free RAM which will make compiled app work stably.
+
+The `.fap` files under the release tab are already cleared with this script, so if you just want to use this app without modifications, just forget about it and download the latest one from releases.
