8051 What does SDCC do part 1 ?
1. Introduction and Problem Statement A good way to learn what a compiler really does when transforming a C source code into a binary is to disassemble the binary and compare it with the C source code. It is especially true for 8 bits microcontrollers like the 8051. In order to test SDCC we are going to use the following C source code. /*…
To understand what SDCC does when translating C source code into binary, we should examine the compiled output for the 8051 microcontroller. For this purpose, we'll use a sample C program and transform it using SDCC. The program includes global variables, a function with parameter passing and local variables, and a main function containing complex control flow. After compilation, we'll transform the Intel HEX file into a ROM file that can be simulated using the 8051 IDE.
