+cache systems.
+
+## Objects
+
+### 1. lv_rb.py - Red-Black Tree Support
+
+Provides debugging support for LVGL's red-black tree (`lv_rb_t`) implementation.
+
+**Classes:**
+
+- `LVRedBlackTree` - Iterator for red-black tree nodes
+
+**Functions:**
+
+- `dump_rb_info(rb, datatype)` - Dump basic red-black tree information
+
+**Usage:**
+
+```gdbscript
+# In GDB:
+python tree = LVRedBlackTree(some_rb_tree)
+python for data in tree: print(data)
+python dump_rb_info(some_rb_tree, datatype)
+```
+
+### 2. lv_cache.py - Cache System Support
+
+Provides debugging support for LVGL's cache system (`lv_cache_t`).
+
+**Classes:**
+
+- `LVCache` - Wrapper for cache objects
+
+**Functions:**
+
+- `dump_cache_info(cache, datatype)` - Dump cache information
+
+**Usage:**
+
+```gdbscript
+# In GDB:
+python cache = LVCache(some_cache)
+python print(f"Cache usage: {cache.get_usage_percentage()}%")
+python dump_cache_info(some_cache, datatype)
+```
+
+### 3. lv_cache_entry.py - Cache Entry Support
+
+Provides debugging support for cache entries (`lv_cache_entry_t`).
+
+**Classes:**
+
+- `LVCacheEntry` - Wrapper for cache entries
+
+**Functions:**
+
+- `dump_cache_entry_info(entry, datatype)` - Dump cache entry information
+
+**Usage:**
+
+```gdbscript
+# In GDB:
+python entry = LVCacheEntry(some_entry)
+python print(f"Ref count: {entry.get_ref_count()}")
+python dump_cache_entry_info(some_entry, datatype)
+```
+
+### 4. lv_cache_lru_rb.py - LRU Cache with RB Tree Support
+
+Specialized support for LRU-based caches using red-black trees.
+
+**Classes:**
+
+- `LVCacheLRURB` - Specialized cache wrapper for LRU RB implementations
+
+**Functions:**
+
+- `dump_lru_rb_cache_info(cache)` - Dump LRU RB cache information
+
+### 5. lv_image_cache.py and lv_image_header_cache.py - Image Cache Support
+
+Provides debugging support for LVGL's image cache (`lv_image_cache_t`).
+
+**Classes:**
+
+- `LVImageCache` - Wrapper for image cache objects
+
+**Usage:**
+
+```gdbscript
+# In GDB:
+python curr_inst().image_cache().print_info()
+python curr_inst().image_cache().print_entries()
+```
+
+## Integration
+
+All these modules are automatically imported and available when using the LVGL GDB scripts. You can access them through
+the main `lvgl` module:
+
+```gdbscript
+# In GDB:
+python from lvglgdb import LVRedBlackTree, LVCache, dump_rb_info, dump_cache_info
+```
+
+## Type Conversion Support
+
+All wrapper classes support multiple input types:
+
+- `gdb.Value` objects (from GDB expressions)
+- `Value` objects (from lvglgdb.value module)
+- Raw pointers as integers (e.g., `0x12345678`)
+
+This allows flexible usage patterns:
+
+```gdbscript
+# From GDB variable
+entry = LVCacheEntry(my_entry)
+
+# From raw memory address
+entry = LVCacheEntry(0x7fff12345678)
+
+# From GDB expression result
+entry = LVCacheEntry(gdb.parse_and_eval("*(lv_cache_entry_t*)0x7fff12345678"))
+```
+
+## Examples
+
+### Debugging a Red-Black Tree
+
+```gdbscript
+# Create tree iterator from variable
+tree = LVRedBlackTree(some_rb_variable)
+
+# Create from raw pointer (0x12345678)
+tree = LVRedBlackTree(0x12345678)
+
+# Iterate through all nodes
+for data_ptr in tree:
+    print(f"Data pointer: {data_ptr}")
+
+# Get tree info
+print(f"Tree has {len(tree)} nodes")
+tree.print_info()
+```
+
+### Debugging a Cache
+
+```gdbscript
+# Create cache wrapper from variable
+cache = LVCache(some_cache_variable)
+
+# Create from raw pointer (0x12345678)
+cache = LVCache(0x12345678)
+
+# Check cache status
+print(f"Cache usage: {cache.get_usage_percentage():.1f}%")
+print(f"Cache enabled: {cache.is_enabled()}")
+
+# Dump full info
+cache.print_info()
+```
+
+### Debugging Cache Entries
+
+```gdbscript
+# Create entry wrapper from variable
+entry = LVCacheEntry(some_entry_variable)
+
+# Create from raw pointer (0x12345678)
+entry = LVCacheEntry(0x12345678)
+
+# Check entry status
+print(f"Ref count: {entry.get_ref_count()}")
+print(f"Invalid: {entry.is_invalid()}")
+
+# Dump full info
+entry.print_info()
+```
+
+## File Structure
