title: How generate REAL random number using STM32 MCU?
body: <p>I'm working on a project with STM32F103E arm cortex-m3 MCU in keil microvision IDE.<br/>
  I need to generate random numbers for some purposes, but I don't want to use pseudo-random numbers which standard c++ libraries are generating, so I need a way to generate REAL random numbers using hardware features, but I don't know how I can do it.<br/>
  Any idea? (I'm a software engineer &amp; not an electronic professional, so please describe it simple :P)</p>
