# 1.22 RNG Random Number

This example application shows how to use the RNG Peripheral library to generate a pseudo-random number.

## Description

The RNG peripheral has two blocks. One of them is called True Random Number Generator (TRNG) and the other is called Pseudo-Random Number Generator (PRNG). The TRNG generates true random numbers that can be used as seed for the PRNG. The PRNG can generate random numbers of up to 64-bits of length. This application shows how to generate a 64-bit pseudo-random number with the help of PRNG and TRNG.

### Setting Up PIC32MZ Embedded Connectivity with FPU (EF) Starter Kit

- Connect mini USB cables from the ‘Debug USB’ and ‘USB-to-UART’ connectors on the board to the computer

## Running the Application

1. Open the Terminal application (Ex.: Tera term) on the computer
2. Connect to the EDBG Virtual COM port and configure the serial settings as follows:
   - Baud : 115200
   - Data : 8 Bits
   - Parity : None
   - Stop : 1 Bit
   - Flow Control : None
3. Build and Program the application project using its IDE
4. Press the switch to generate a 64-bit pseudo-random number (Refer to the table below for switch details)

   Board | Switch Name
   --- | ---
