Jump start your mastery of 8-,16- and 32-bit PIC® MCUs and 16-bit dsPIC® DSCs with the informative user guides that are available for the MPLAB® XC series of C compilers. You'll find the links under the "Documentation" tab on the MPLAB XC Compilers.
In the previous tutorial, gate level minimization of boolean functions was discussed. A boolean function must be expressed in standard form as either sum of products (SoP) or product of sums (PoS). Once a boolean function in case is minimized to SoP or PoS form, it can be easily fabricated as two-level implementation of AND and OR gates. A two-level implementation is preferred so that there is minimum delay in signal propagation through logic gates from input to output of the digital circuit. 
In the previous tutorial, all the possible boolean functions between two variables were discussed. In the tutorial - Boolean Algebra, various theorems and postulates were stated which are useful in simplifying a boolean expression or function. However, the simplification of a boolean expression using theorems and postulates is quite cumbersome and prone to errors. Therefore, for simplification of boolean expressions, some map methods were devised. The most commonly used map method is Karnaugh Map or K-Map. 
The IoT device designed here is a weather station built by interfacing a character LCD with the ESP8266 board. The device fetches the weather data of the location it is installed and
