Detailed Description

template<typename Type, intptr_t BaseAddress = 0, typename StorageType = uint16_t>
struct etl::small_ptr< Type, BaseAddress, StorageType >

Compressed pointer to specified size. Intended to be used as a drop in replacement for native pointers.

Uses the base address to calculate an offset, which will be stored internally. If used on micro controllers, the base address should be set to the start of RAM. See your linker script.
