The objectives of this project were (1) to make an object float, by means of magnetic levitation and controlled by an Arduino Nano and (2) documenting the whole process allowing other people to build one on their own. There were some requirements, too. First, I wanted an object of a certain size and weight, floating …
Have you been using float or double variables to perform mathematical operations on embedded systems without a Floating-Point Unit (FPU)? You are doing it wrong! Thatβs incredibly inefficient. UseΒ fixed-point representation instead. An FPU isΒ an hardware block specially designed to carry on arithmetic operations on floating point numbers. Even though the C/C++Β code may work without an …
