Educational implementation of lookup tables for special functions on microcontroller PIC

The main objective of this article is to detail the teaching of the implementation of lookup tables that address specific mathematical functions -such as the error function, among others-, using economical hardware resources. At the same time, a didactic application of these constructs is presented. This implies that the development of this application is centered around PIC and LCD microcontrollers, adapted to the pedagogical and economic needs of students in technical high schools and engineering. This set of pragmatic educational tools facilitates understanding of these mathematical functions and their implementation. Additionally, the use of low-cost components allows students from economically disadvantaged regions, particularly those from low-income countries, to participate in the implementation of this microcontrolled system.
