Introduction

Spruce -LinkSprite STM32 ARM cortex board can be used with OpenJTAG and is compatible withmini ARM cortex-M3 board . It can be used in GCC+Eclipse+openocd+openJtag and Arduino enviroment! When used in Arduino enviroment, it is compatible with Maple.

Spruce has Arduino compatible shield pins, all the Arduino shields can be used on LinkSprite STM32 cortex board. Arduino similar IDE can be used to download Arduino code to Spruce board.

Spruce Hardware Resource

  • CPU: STM32F103VET6, TQFP 100 pins FLASH:512K BYTES, SRAM:64KBYTES
  • 1 JTAG debug interface
  • 1 power LED indicattor (Green), 1 status LED (Blue)
  • 1 RS232 port, Need crossover cable to talk to PC
  • Support 3 pin ISP
  • 1 USB2.0 SLAVE port
  • 1 Micro SD(TF) slot, uses SDIO
  • 1 SPI interfaced AT45DB161D(2M BYTES) serial FLASH
  • 1 functional botton
  • 1 RTC battery socket
  • 1 RJ45 Ethernet port
  • All unused GPIO pins are connected to external headers.
  • LCD NOT INCLUDED


Arduino IDE Environment

In Arduino IDE enviroment, it is fully compatible with maple, and all arduino shield. The bootloader is flashed through RS232 port, and the arduino program is downloaded frm USB port. The driver of the USB port can be found at the maple IDE, which can be downloaded from the maple IDE version for Spruce.


GCC+Eclipse+OpenOCD+OpenJTAG

Spruce also supports development using GCC+Eclipse+OpenOCD+OpenJTAG.

Eclipse Enviroment Setup and User Guide

Eclipse is a Java development enviroment, but its architecture also supports other languages. In this article we will introduce how to use C/C++ development Toolkit CDT) together with Sourcery G++ Lite for ARM EABI to do embedded ARM development work,

We need to install JAVA JDK before install Eclipse. The JAVA JDK can be downloaded from:download

Eclipse1.jpg

After registration, we can download jdk-6u22-windows-i586.exe and install.

Download Eclipse IDE for C/C++ Developers, it has Eclipse and CDT. The download link is: Eclipse IDS

Eclipse2.jpg

Select Eclipse IDE for C/C++ Developers,

Eclipse3.jpg

After download, unzip eclipse and run Eclipse.

Install ARM plug-in for Eclipse:

In menu, select Help – > Install New Software, and enter:

http://gnuarmeclipse.sourceforge.net/updates

in the "work with" address bar:

Eclipse install 1.jpg

After several seconds, it will display GNU ARM C/C++ Development Support, click GNU ARM C/C++ Development Support, and unclick Group items by category:

Eclipse install 2.jpg

Click Next untill Finish, and wait for the downloading update.

In menu, select " Help – > Install New Software" and enter http://www.zylin.com/zylincdt in "work with".

After several seconds, it will display an option " Zylin Embedded CDT". Select it and click "next" until "finish", wait for downloading.

Install Sourcery G + + Lite

It can be downloaded from:Download

Select IA32 windows installer.

IA32install.jpg

Download arm-2010q1-188-arm-none-eabi.exe. After finish installation, we have:

IA32install 02.jpg

Install remote support by doing: Help – > Install New Software, and select " All Available Sites" in "Work with" pull down menu. Select " Group items by category" option, and select

General Purpose Tools

  • Dynamic Languages Toolkit – Remote Development Support
  • Remote System Explorer End-User Runtime
  • Remote System Explorer User Actions

IA32install 03.jpg

Create new project

We can now create new project " Sourcery G++ Lite" in menu "File", and do compilation and link.

  • 1. Run eclipse, and select the location of the newly created project file " workspace".
  • 2. Creat a new project " Sourcery G++ Lite" project:

input porject name under "File->new->c project->", and select " Sourcery G++->finish" in " toolchains":

  • 3. add files to project, and edit application file.

Right click project file name, and select "refresh" to load the changed file directory to "Eclipse".

  • 4. Set properties:

Right click project file name and select " properties" ->C/C++ General->paths and symbols->, select " GNU C->add->workspace-> inlude " under " GNU C->add->workspace->", and ->apply ( ok )。

Create 01.jpg

"properties" ->C/C++ Build->settings->, and select " ARM Sourcery Windows GCC Linker ->General->" under " ARM Sourcery Windows GCC Linker ->General->", and select (*.ld)- in " script file", ->ok .

Enter the absolute path of .ld file.

Create 02.jpg

  • 5. Build

Right click project file and click " build project" or " clean project "

Spruce Used to Control LinkSprite Robot Platform

On LinkSprite Spruce, STM32 MCU is used. STM32 has ARM Cortex-M3 core. It can be used on Keil development environment and Arduino IDE.

LinkSprite Arduino Robotics Kit is an Arduino based Robotics kit.

The hardware included:

  • Robotics platform
  • Two-Channel DC Motor Driver Breakout (L298 Chipset)

DC motor.jpg

  • Path sensor board

Path sensor board.jpg

  • three infrared obstacle sensors

Obstaclesensor.jpg

  • Arduino board is NOT included
  • Battery holder
  • Jumper wires

The platform comes with the metal base, two rubber tires, one ball caster metal, and two gearmotors.

Connection instructions

Two-Channel DC Motor Driver Breakout to Arduino Uno:

  • I1 -> pin 2 of spruce
  • I2 -> pin 1 of spruce
  • I3 -> pin 5 of spruce
  • I4 -> pin 6 of spruce
  • EA -> pin 11 of spruce
  • EB -> pin 12 of spruce
