lwprintf: A Tailored printf Implementation for Embedded Systems - Say Goodbye to Bloat and Embrace a Lightweight printf Library

In embedded system development, the <span>printf</span> function is like an old friend, facilitating debugging and information output. However, the standard library’s <span>printf</span> is often too large, consuming precious memory resources, which is a heavy burden for resource-constrained embedded systems. Today, we are excited to introduce a lightweight and efficient <span>printf</span> library—lwprintf—that will completely change your … Read more

Output Formatting in MATLAB

The results of calculations in MATLAB are displayed on the screen after each assignment statement when the semicolon is omitted. The output format can be adjusted using the <span>format</span> command. However, more detailed control over the output can be achieved using multiple functions. <span>disp</span> function is used to display the value of a variable according … Read more
