• LTSpice – adding an element model to the schema

    LTSpice has a large built-in library of elements. But sometimes we need an element that is not in the library. Electronics manufacturers themselves provide models of elements that they publish in the form of text files.The easiest way is to add an element to the library. But sometimes I want to be able to send someone a simulated circuit. In this case, we had to attach all the elements in the library, and someone else would have to import it. But there is another way out of this situation and I will present this solution.

  • The Low-Layer (LL) Library from ST

    By programming ST microcontrollers, you could now use the HAL, SPL (Standard Peripherals Library), or work on registers. But recently there has been a new opportunity.These are the Low Layer drivers. The Low Layer (LL) drivers are designed to offer a fast light – weight expert – oriented layer which is closer to the hardware than the HAL. Now I will show you how to start using the LL with CubeMX. Not all microcontrollers are supported. ST started to support the Cortex-M0 + family. For this family I will show an example.
