Dynamic embedded memory

Dynamic embedded memory management part 2

As a follow-up to the previous article, here are some tips to determine the use of the heap by your program.

In C

In C, it is quite difficult to estimate heap usage because the allocator functions are type-erased, i.e. the return type of the allo...

Cycle precise delay loop in C++

Implementing a cycle-precise delay loop in C++ for embedded system

In a recent work on Marlin's printer firmware, I found a pending pull request about waiting for precise, ideally nanosecond timed, delays.

While it looked like easy at first, the implementation proved tricky. This post explains...

Dynamic embedded memory

Dynamic embedded memory management

When you have an embedded system with limited memory, you are forced to think twice about how you are going to spend your budget. The most obvious solution is to avoid dynamic memory allocation and deal with static pool of memory you are managing yourself compl...
