Fixed bug in HD44780 display when using 8 bit data bus

The library now compiles in GCC 4.7.0 although the supplied libraries are still compiled via GCC 4.3.3 (WinAVR-20100110). This is largely due to some errors in GCC 4.7.0 that I have reported to gnu. However: those of you who have reported compile errors in version > 4.3.3 should now be able to compile - but don't moan to me about any issues if you do so! To find which version of the compiler you are using then at a command prompt type in:

avr-gcc --version

You will need to make sure that you have downloaded the latest Project Designer and re-generate your projects (standard practice).

If you are using my Downloader then Version 1 is now being put on ice so within the Downloader select WebbotLib V1 and then click the 'Properties...' button.If the Remote URL says:- 'http://sourceforge.net/projects/webbotavrclib/files' then change it to 'http://sourceforge.net/projects/webbotavrclib/files/Version1'

This is necessary as the Version 1 codebase used to be the default download from SourceForge whereas the default is now Version 2

Added support for two real time clocks - DS3234 and DS1307 (Version 2.07 only)
Added Dallas 1 Wire support (Version 2.07 only)
Added support for the DS18B20 temperature sensor (Version 2.07 only)
Added support for HMC5883L compass
Added support for BMP085 pressure sensor (with functions to return altitude and depth)
Sharp wide angle distance sensors now return the minimum distance across all 5 sensors rather than the average

Version 2.07 also contains an alpha release for the 4D Systems serial graphical displays. Not all functionality is yet supported but Project Designer will generate some example code to show-off some of the abilities.

N,B. Pressure sensors now return values in Pa rather than kPa (for better accuracy) - so if you are using them already then read the updated section of the manual.

Project Designer now has all 3 revisions of the Sparkfun Razor board

This is a maintenance release.

It fixes a potential issue with the use of rprintf under interrupts - such as with the DroneCell - but could apply to other devices as well. The longer they are up and running then the increased chance of something going wrong.

All PWM based motor controllers now allow you to specify the actual PWM frequency ( default is the previous version of 10kHz) in Project Designer or as an extra parameter to the 'init' function.

So perform a 'clean' and then regenerate your code in Project Designer if you are using it. If you aren't using Project Designer then recompiling will show errors with your motor controller initialisation calls (read the manual) you will note that you have to add the PWM frequency as an extra parameter.

The DroneCell SMS code has been modified to make sure thay you make use of the return code which indicates whether or not the DroneCell is currently capable of sending a SMS message. Failure to do so willnow result in a compiler warning. See the manual and/or example code produced via Project Designer to see what your code should actually look like!

After a long haul the new C++ option is here (in Version 2.05).

Project Designer now gives you the option to generate C or C++ code but note that if you change from one to the other then it is recommended that you use seperate project folders. The main reason being that, if your project is called MyProject, then you can end up with a MyProject.c and a MyProject.cpp which are both compiled to MyProject.o and so the makefile gets confused as to which one to use.

As a result of some of the changes required by Version 2.05 then a new Version 1.32 has also been released so that it is compatible with Project Designer. Hence, after upgrading to either of these versions, you should regenerate your code from Project Designer. If you are using version 1 without Project Designer then read the release notes in the documentation as there some changes you may need to make to your code by hand.

If you are using a GPS then you should also check out the release notes as there are some small code changes you will need to make plus the longitude and lattitude readings are now returned in degrees rather than radians.

Have been working long and hard on a C++ version of WebbotLib that sits alongside the existing C version.

The code was fairly quick to implement but am now having to revisit 300+ pages of documentation - which is taking a while!.

Let me know if this is of interest !! Can always use some testers !
