Project 1 - Interfacing a 16*2 LCD with Arduino using I2C protocol

1.Perform Static Code Review Analysis for “C:\**\LDRA_workarea\Examples\C_tbrun_examples\Ggrocers.c” (Single .c file), modify the Code to remove violations and make it compliant with MISRA: C 2012 & CERT standards. Static code analysis is a method of debugging by examining source code before a program…
