| | Linux driver for USB tower
|

Hi, I have a working linux driver for the lego USB tower; so far it has only been tested on kernel 2.4.14 on a uhci system, where it has worked without any problems. Anyone feel like testing it out on their own system (to use it, you will need to be (...) (22 years ago, 28-Jun-02, to lugnet.robotics.rcx.nqc, lugnet.robotics.rcx.pbforth)

Thank you, kind sir, for that small but important lesson in C programming. That was the problem. (And, for everyone's information - FEI - Ferrari's book also has Main() capitalized.) Trevyn Watson <4tee2@rogers.com> wrote in (...) (22 years ago, 21-May-02, to lugnet.robotics.rcx.nqc)

(...) The code on page 107 has "main()" capitalized (i.e., "Main()") and it shouldn't. The error I get is "task 'main' not defined". I'm relatively certain it is a capitalization problem. John Hansen (URL) (22 years ago, 21-May-02, to lugnet.robotics.rcx.nqc)

Did you capitalise "Main"? It doesnt seem to work if you do. NQC is case sensitive, just like C. Trevyn. (...) (22 years ago, 21-May-02, to lugnet.robotics.rcx.nqc)

I get this error - "main() not defined" - when compiling. The code is copied straight from the Ferrari book. While C is the language of my choice, the line of code isn't so obtuse as to hide errors from me. So probably there is some other requisite (...) (22 years ago, 20-May-02, to lugnet.robotics.rcx.nqc)

I believe any data source (not just timers/sensors/variables) can be used in SetUserDisplay. The big limitation is that local variables cannot be used since the display is updated in a global context independent of the tasks. If you know of data (...)

Oops. Looks like a bug in the NQC API file. I just fixed the bug in the NQC source, but it's not major enough to warrant a new release yet. In the meantime, you can add the following lines to the top of of your source file as a work-around: #undef (...) (22 years ago, 8-May-02, to lugnet.robotics.rcx.nqc)

SetUserDisplay does not work like that. You need to specify either a sensor, timer, or global variable. Once you have done that it will continuously update the display as the value changes. In your case you should write your program something like: (...) (23 years ago, 6-May-02, to lugnet.robotics.rcx.nqc)
