Now, Winavr have update a new version WinAR20080610. But it have problem when use AVRdude (include with WinAVR20080610 package) with USBasp AVR Programmer. AVRdude can’t detect USBasp device, have error same following:

avrdude: error: could not find USB device “USBasp” with vid=0×16c0 pid=0×5dc

Because a driver version 0.1.10.1 (USBasp driver) not compatible with libusb DLL version 0.1.12.1 in WinAVR20080610. If you have a old USBasp driver still in your computer. must uninstall before. Can uninstall by goto Star->Control Panel->System->Hardware->Device Manager When Windows recognize with your USBasp device.

Download a new Windows driver (libusb DLL 0.1.12.1) for USBasp from USBasp-driver-0.1.12.1.zip unplug USBasp then plugin USBasp to USB Port again. Windows will recognize and request to install a new driver.

When install complete, test USBasp device again. Now work prefect.

Thanks thomasATulrichradigDE from avrfreaks for a new driver. 

On Ubuntu we want a good IDE for developing programs for the microcontrollers, such as Atmel AVR, ARM MCUs. Eclipse is a prefect IDE with many features, come with Open Source and have many document, plugin.

But on Ubuntu 8.04 not have Eclipse 3.3 in repository, you must use manual install.

1. Before install Eclipse 3.3 you must have a Java 6 from SUN on your computer. check on Ubuntu

$java -version

If your computer have a Java GNU version, you must install a Java 6 from SUN

$sudo aptitude install sun-java6-jdk

When install complete, check a default jvm by:

$update-java-alternatives -l

you should get output similar to this:

>java-6-sun 63 /usr/lib/jvm/java-6-sun
>java-gcj 1042 /usr/lib/jvm/java-gcj

set the right jvm by use command:

$sudo update-java-alternatives -s java-6-sun

and insert /usr/lib/jvm/java-6-sun on the top of file /etc/jvm ($sudo gedit /etc/jvm)

$cat /etc/jvm
# This file defines the default system JVM search order. Each
# JVM should list their JAVA_HOME compatible directory in this file.
# The default system JVM is the first one available from top to
# bottom.
/usr/lib/jvm/java-6-sun
/usr/lib/jvm/java-gcj
/usr/lib/jvm/ia32-java-1.5.0-sun
/usr/lib/jvm/java-1.5.0-sun
/usr

Check a version of Java again.

$java -version
java version “1.6.0_06″
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Client VM (build 10.0-b22, mixed mode, sharing)

All Ok

2. Download Eclipse 3.3.2 from here

When download complete, make a new folder for install Eclipse

$sudo mkdir /usr/local/opt

Extract Eclipse archive to a new folder

tar -zxf your.downloaded.eclipse.version.tar.gz -C /usr/local/opt

Run Eclipse

$cd /usr/local/opt/eclipse
$./eclipse

Enjoy!!

PS. Eclipse out a new version 3.4 but i still never test it yet.

From i introduce how to setting H-Link with H-JTAG Server Software in recent post. Today i will open case H-Link for show inside.

H-Link case : 25 pin D-SUB Cover easy for open.

H-Link have two buffer. for input, output signal between ARM board and Parallel Port. Can protect a high noise current and give a stable signal when use with long Parallel Port Cable ( I tested with 1.8 meter Parallel Port Cable, It work perfect )

Have a good news, in next version H-JTAG Software have plan to supports Cortex-M3
