4. Getting Started

4.1 Requirements

• A PC system with one available USB

2.0/3.0 port

• Windows 7/8/10 with 32/64-bit

Operation System

• An Arduino UNO host board R3

• A USB 2.0 cable Type A/B

4.2 Software Installations

1. Downloading the Arduino software

IDE (Integrated Evaluation

Environment). This software is

required to program the Arduino UNO

host board

• Download the latest version of

Windows installer from

(https://www.arduino.cc/en/Main)

2. Installing Arduino application software and drivers

• Click on “Arduino-x.x.x-windows.exe” file to install Arduino application software and

USB drivers

3. Downloading Avalanche test program in zip format from (http://www.avalanche-

technology.com/). This zip file contains the “Dkino_customer” folder which contains

Arduino application software and Avalanche source-code

4.3 Connecting the Arduino UNO Host Board

Follow the step-by-step instructions in the following orders below to configure and connect the

Arduino UNO host board to your computer:

1. Attach the Avalanche SPI SPnvSRAM evaluation board on top of the Arduino UNO host

board via the UNO R3 headers (refer to figure 1 on page 5)

2. Connect the Arduino UNO host board to your computer’s USB port using the USB 2.0 cable

Type A/B. The green power LEDs on both the Arduino UNO host board and the Avalanche

SPI SPnvSRAM evaluation board should go on

3. For first time installation, Windows should initiate the USB driver installation process. You

can check to ensure the USB drivers have been properly installed by opening Windows

Device Manager, and looking

under “Ports (COM & LPT)”.

Windows should assign COM port

# to the Arduino UNO host board.

If there is no COM port has been

assigned to the Arduino UNO host

board, then remove and re-insert

USB connector from/into PC’s USB

port for Windows to re-enumerate

USB port. If that still doesn’t work,

then you may need to re-install the

USB drivers.

4.4 Programming the Arduino UNO Host Board

Follow the step-by-step instructions below to program the Arduino UNO host board with

Avalanche test program:

1. Open the “Dkino_customer” folder, and double-click the Dkino_customer.ino program file

to launch the Arduino IDE

2. Select “Tools” → “Port”. Make sure that the correct COM port is selected for the Arduino

UNO host board (refer to Figure 5)

3. Select “Tools” → “Boards” → “Arduino/Genuino Uno”

4. Select “Sketch” → “Verify/Compile” to compile the Avalanche code example

5. Select “Sketch” → “Upload” to store/upload the binary sketch file to the Arduino’s EEPROM

4.4.1 Configuring PuTTY

Follow the step-by-step instructions below to configure the PUTTY UART terminal:

1. Double click on Putty icon to open PuTTY Configuration Window

2. Under “SSH”, select “Serial”. Under “Flow control” pull-down menu, select “None” (refer to

Figure 7)

3. Under Category, select “Terminal”, and check “Implicit CR in every LF” checkbox (refer to

Figure 8 )

4. Select “Session”. Under “Connection Type”, select “Serial” (refer to Figure 6)

5. In the “Serial line” box, type “COMx” where x is the COM port # that Windows has assigned

to Arduino UNO board (refer to Figure 8)

6. In the “Speed” box, type “115200” to set the baud rate (refer to Figure 8)

7. In the “Saved Sessions” box, type “COMx” where x is the COM port # that Windows has

assigned to Arduino UNO board (refer to Figure 8)

8. Click “Save” to save the COMx configuration file (refer to Figure 8)

9. Click “Open” to launch PuTTY (refer to Figure 8)

10. The Arduino UNO host board and the Avalanche SPI SPnvSRAM evaluation board are now

up-and-running. The Terminal Monitor window will display read/write/compare test

results performed on the Avalanche SPnvSRAM device as indicated in Figure 9
