rnga_random#

Overview#

The RNGA is a digital integrated circuit capable of generating the 32-bit random numbers. The RNGA Example project is a demonstration program that uses the KSDK software to generate random numbers and prints them to the terminal.

Prepare the Demo#

Connect a serial cable from the debug UART port of the board to the PC. Start Tera Term (http://ttssh2.osdn.jp) and make a connection to the virtual serial port.

  1. Start Tera Term

  2. New connection -> Serial

  3. Set apropriate COMx port (x is port number) in Port context menu. Number is provided by operation system and could be different from computer to computer. Select COM number related to virtual serial port. Confirm selected port by OK button.

  4. Set following connection parameters in menu Setup->Serial port… Baud rate: 115200 Data: 8 Parity: none Stop: 1 Flow control: one

  5. Confirm selected parameters by OK button.

Running the demo#

When the demo runs successfully, from the terminal you can see:

RNGA Peripheral Driver Example Generate 10 random numbers: Random[0] = 0xE1554295 Random[1] = 0x827AD456 Random[2] = 0x9A1CBE1E Random[3] = 0x4354CB53 Random[4] = 0xFE3B2494 Random[5] = 0xEDAB3F7D Random[6] = 0x9AB91722 Random[7] = 0x4F54D999 Random[8] = 0x492414D1 Random[9] = 0x84611992
