The basic difference between malloc and calloc function is that calloc() takes two arguments and the space is initialized to all bits zero while malloc takes only one argument and the space value is indeterminate. Both malloc and calloc are memory management functions which use to allocate the memory dynamically. In C language, calloc() gives […]

In the article, we will see how to read and write the internal EEPROM of PIC Microcontrollers. Generally, PIC microcontrollers come with some built-in EEPROM which is used to store data permanently. An EEPROM is a non-volatile memory that means it can store the data permanently without any power supply. EEPROM stands for Electrically Erasable
