MCU/WISE-1570 SDK

Introduction

This document is description about WISE-1570 software development kit (SDK). It includes source tree of SDK, development environment, flash programming…etc.

Setup Development Environment

Preparing for Hardware

The user needs to prepare for hardware as following:

• For mote, WISE-1570, WISE-1500 and WISE-ED20 or WISE-ED22.
• PC running LINUX operating systems such as Ubuntu 16.04.1.

Please refer to the following steps for setup a WISE series of boards before using WISE-1570 SDK.

Step01: Please prepare boards as below.

①WISE-1570
The user must to choose the CN1 on WISE-1570 as below is connected to WISE-ED20 or WISE-ED22 through FPC.

②WISE-1500

③WISE-ED20

④SW2 on WISE-ED20

• Please check pin1 and pin2 to “ON” as default.
• Switch pin1 to “ON”: flash programming, “OFF”: boot from flash.

⑤CN2 on WISE-1500

• Booting into the mode of network connection when both 3.3V and GPIO0 are opened.
• Booting into the mode of console of API when both 3.3V and GPIO0 are shorted.

⑥SW3 on WISE-1500

• Please check pin1 and pin2 to “OFF” as default.
• Switch pin2 to decide whether running “backup to default” while device booting. “ON”: enabled, “OFF”: disabled.

⑦One reset button on WISE-1500 and the other on WISE-ED20

⑧Micro USB connector

• Power supplies for UART3 debug port.

⑨Com port

• No supported.

Step02: Connect the WISE-ED20 to PC using micro-USB cable.

The device will be visible in the Device Manager as below after FTDI driver installed. The user can find the FTDI driver in source tree.

ARM mbed

The ARM mbed is IoT device platform and it has a lot of resources for IoT development. We supported ARM mbed OS on WISE-1570 to make user easily to get started and obtain great benefit from ARM mbed.

mbed CLI

The mbed CLI is command-line tool. The user needs to setup CLI for WISE-1570 SDK and please follows the steps to install related tools. For more details, please refer to mbed CLI.
Note: We expected the user setups mbed CLI in Linux as default. If the user preferred Windows, ARM mbed provides the Video tutorial for manual installation.

• Install Python

mbed CLI supports Windows, Linux and Mac OS X operating systems. You can select the OS you prefer to work with. mbed CLI is a Python script, so you’ll need Python to use it. The version 2.7.11 of Python has been verified with mbed CLI.

Note: mbed CLI is incompatible with Python 3.

 
Install python 2.7.11 
$ sudo wget https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz
$ tar zxvf Python-2.7.11.tgz
$ cd Python-2.7.11
$ sudo ./configure 
$ sudo make altinstall

Check the python version
$ python --version

• (Optional) Install Git or Mercurial

If you would like to maintain your source code in repositories, you can continue with the next step. mbed CLI supports both Git and Mercurial repositories, you can install which one you prefer:

Git - version 1.9.5 or later.

Mercurial - version 2.2.2 or later.

If you don’t want to use repositories, you can just skip it.

Git install commands as follow

Install Git latest
$ sudo add-apt-repository ppa:git-core/ppa
$ sudo apt-get update
$ sudo apt install git

Mercurial install commands as follow

Install mercurial latest
$ sudo add-apt-repository ppa:mercurial-ppa/releases
$ sudo apt-get update
$ sudo apt-get install mercurial

• Install GCC

mbed CLI invokes the mbed OS 5 tools for various features, such as compiling, testing and exporting to industry standard toolchains. To compile your code, you will need either a compiler or an IDE:

 Compilers: GCC ARM, ARM Compiler 5, IAR.

 IDE: Keil uVision, DS-5, IAR Workbench.

We select GCC ARM Embedded, so you can install version 4.9 of GCC ARM Embedded.

Install GCC ARM Embedded
$ sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa
$ sudo apt-get update
$ sudo apt-get install gcc-arm-embedded

Note: When installing the Arm Compiler 5 on a 64-bit Linux machine, you may need to also install the i386 architecture package:

 
$ sudo dpkg --add-architecture i386
$ sudo apt-get update
$ sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 

• Install mbed CLI

You can get the latest stable version of mbed CLI from PyPI

 
$ pip install mbed-cli 

Note: On Linux or Mac, you may need to run with sudo.

• Other necessary package

$ sudo pip install colorama
$ sudo pip install pyserial
$ sudo pip install prettytable
$ sudo pip install jinja2
$ sudo pip install intelhex
$ sudo pip install junit_xml
$ sudo pip install mbed_ls
$ sudo pip install beautifulsoup4 
$ sudo pip install fuzzywuzzy
$ sudo pip install mbed_host_tests
$ sudo pip install mbed_greentea

mbed CLI configuration

• GCC_ARM_PATH

Set GCC_ARM_PATH to the binary directory of your GCC Arm installation

$ mbed config -G GCC_ARM_PATH "/home/erick/gcc-arm-none-eabi-4_9-2015q3/bin"
[mbed] /home/erick/gcc-arm-none-eabi-4_9-2015q3/bin now set as global GCC_ARM_PATH

Flash Programming

For flash programming, the user can do it through WISE-ED22 or WISE-ED20 with different programming tool. Please refer to the following steps for flash programming.

Programming through WISE-ED22

Please refer to WISE-ED22 for flash programming.
