We're gearing up to release 2.00 in a few more days, but I wanted to post a release of 2.00 in a Preview form for everyone to try out over the weekend.
http://robotc.net/downloads/ROBOTCforMindstorms_200_Preview.exe

Licensing:
- Your 1.x license is good for 2.0. There will be no upgrade fee for 1.0 users upgrading to 2.0.

Not in 2.0:
- NXT Color Sensor Support - It's coming soon after 2.00 is out the door. (2-4 weeks after)
- RS-485 support - Probably a 2.5 release target
- Robot to Multi-Robot communication over BT - 2.5 or 3.0 release target.

Our current To-Do list:
Add more documentation - Unreferenced Functions - Note Tasks and Function limits (20,140)
Clean up FTC folder of Sample Programs
Update Start Page Update for 2.00
Update What's new - ROBOTC HTML document
Joystick *misconfigured* error box - harmless, but annoying.
Read-Only Flag on Sample Programs
Clean up a few screens/text boxes

If you find any bugs/issues - please keep them in this thread or e-mail them to support@robotc.net

A potential bug : When I use 'nxtDisplayString' it displays the text as BIG, whereas 'nxtDisplayStringAt' shows it as standard.
Version : RobotC 2.00 (785) Oct 30, 2009

Not sure if it is a bug or a coding error or a logical error, but you might also want to take a look at this post : viewtopic.php?f=8&t=1925
As if the synchronisation of the two engines doesn't work properly when you change the speed. Also not sure why the robot does not stop when you put the power on zero and do something else after it (like play a sound)

I was hoping this was fixed with version 2.0. Sometimes the IDE crashes when a c program is compiled. This is super frustrating to me not to say how frustrating it is for students learning to program. Here are the steps to re-create the crash every time:

open sample program Motors with For Loops Tetrix.c (default loaded because it was the last open program)
open sample program Motors with While Loops Tetrix.c
recompile progam Motors with While Loops Tetrix.c
close above Motors with While Loops Tetrix.c
recompile with Motors with For Loops Tetrix.c

crashes...


simplified:
open sample program Motors with For Loops Tetrix.c (default loaded because it was the last open program)
open sample program Motors with While Loops Tetrix.c
close sample program Motors with While Loops Tetrix.c
recompile with Motors with For Loops Tetrix.c

crashes

Windows Vista Home Premium
Version 6.0 (Build 6001: Service Pack 1)

Robotc for mindstorms 2.0 Preview

same with RobotC for mindstorms 1.93

I have seen the crash with Windows XP as well although I haven't verified the above steps to recreate.

Any plans on fixing this?

That crashing issue has been reproduced with 1.93, but not with 2.00.

I just tried it on XP, VISTA and Win7 and could not reproduce.

Do you think I need to clear out the registry? I did not do this when I installed 2.0.

Hi,

I've been using v2.00 for one week very frequently.
There is one exception violation that keeps coming back. The Exception type is 'Float to short conversion out of range(35). It always happens at the same program statement: Motor[MotorA]=rightSpeed;
The variable rightSpeed is an integer. The motor is under PID control. It always happens when there is quite a lot of strain on the motor, for example when it changes direction or when something gets stuck in the drive train. I don't know if the value of rightSpeed has any influence on the error.

I am quite sure this error is not in my program as there are no type conversions in this program statement. I suspect the error is somewhere in the PID algorithm.

Generally by the time an exception is thrown, the firmware PC ("Program Counter") has already moved to the next instruction. So the exceptiion reports on the instruction following the instruction that caused the exception. Best to post your complete program if you want help with this.

What's the ETA on an official 2.0 release? I have to prep for a class I'm teaching next semester and wondering if I should start planning with the Preview, or wait a couple of weeks for the official. Thanks,

Albert

Albert,

2.0.1 is out, you can download it here: http://www.robotc.net/download/nxt/

Thank Xander, totally missed the release announcement. Nice to do my planning with the official version 2 instead of the preview.
