# Memory Allocators Shows how to place standard containers in specific memory and query the heap with `idfxx::memory`. ## What it demonstrates - Storing a `std::vector` in internal DRAM with `idfxx::dram_allocator` - Allocating a DMA-capable buffer with `idfxx::dma_allocator` - Combining, testing and removing `idfxx::memory::capabilities` flags - Reading total and free heap size by capability with `total_size()` and `free_size()` - Reading detailed heap statistics with `get_info()` - Checking heap integrity with `check_integrity()` The example uses the exception-based API (`CONFIG_COMPILER_CXX_EXCEPTIONS=y` in `sdkconfig.defaults`). ## Hardware required - Any ESP32-series development board ## How to use Create a project from this example: ```bash idf.py create-project-from-example "cleishm/idfxx_core:memory_allocators" cd memory_allocators ``` Then build and flash it, then watch the serial output: ```bash idf.py set-target esp32 idf.py -p PORT flash monitor ``` Replace `esp32` with your target and `PORT` with your board's serial port. Press `Ctrl-]` to exit the monitor.
To create a project from this example, run:
idf.py create-project-from-example "cleishm/idfxx_core=1.2.0:memory_allocators"
