Advanced Embedded Programming | True Random vs Pseudo Random? The Ultimate Guide to Secure Random Number Generation in Microcontrollers
01Introduction: In C language for microcontrollers, due to resource limitations, pseudo-random number algorithms are usually employed. 02Common Methods 1. Standard Library Function Method (Requires Hardware Support) Note: Some microcontroller standard libraries may not support the rand() function. #include <stdlib.h> #include <time.h> // Initialize random seed (requires external variable, such as ADC noise) void init_random() { … Read more
