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.

Downloading and building the application

To build the application, refer to the following table and open the project using its IDE.

Setting up the hardware

The following table shows the target hardware for the application projects.

Setting up PIC32MZ W1 Curiosity Board

• Connect the Debug USB port on the board to the computer using a micro USB cable
• On the GPIO Header (J207), connect U1RX (PIN 13) and U1TX (PIN 23) to TX and RX pin of any USB to UART converter (for eg: USB UART click board)

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
   PIC32MZ W1 Curiosity Board	SW1

5. Observe the following output in the console:
