The Art of Representing Floating Point Numbers as Integers

The Art of Representing Floating-Point Numbers as Integers

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! That’s incredibly inefficient. Use fixed-point representation instead. An FPU is an hardware block specially designed to carry on arithmetic operations on floating point numbers. Even though the C/C++ code may work without an

SIMPL Revisited Again but this time its personal

SIMPL Revisited – Again, but this time it’s personal

In May 2013, I learned about Ward Cunningham’s Txtzyme language – a very simple serial command interpreter which allowed basic control of microcontroller function using a serial interface. I wrote about it here: Txtzyme – A minimal interpretive language and thoughts on simple extensions Tytzyme was about as easy as a “language” could get, it

OLED displays for still better prices

OLED displays for still better prices!

The most advanced display technology – OLED, goes ahead into many industrial products thanks to its advantages. From a certain point of view exactly the industrial environment properly checks features of displays and especially in critical applications extreme thermal resistance a big advantage (immediate response even in frost). As it uses to be, new technologies

TE Connectivity Power Tripple Lock – locked three times for ever

TE Connectivity Power Tripple Lock – locked three times, for ever

Universal connectors for interconnection of leads (wire-to-wire) as well as leads to a PCB (wire-to-board) are necessary every day and practically everywhere. In industrial applications we usually need various connectors. “Various” usually means almost uncountable amount of types, that´s why it´s usually a big advantage if it´s possible the same connector for several applications. This
