  Re: USB tower/Linux/Firmdl not working nicely together
 
Bart, (...) The problem is that USB tower on linux is not supported by firmdl3/dll at the moment. I'm working on that capability now. If I can, my intent is to have it work for 2.4 (user added driver) and 2.6 (built-in driver) kernels. The USB tower (...) (21 years ago, 6-Mar-04, to lugnet.robotics.rcx.legos)

(...) Eh... Never mind this bit. I just had a gander at Kekoa's rcxlib and he already handles this correctly in debug_value(). Should've known! :-) Mark (21 years ago, 2-Mar-04, to lugnet.robotics.rcx)

Much better and more accurate answer from Mark - who knows a lot more about GCC that I do :-) I should stick to commenting on assembly language stuff. Ralph (...) <snippage> (21 years ago, 2-Mar-04, to lugnet.robotics.rcx)
 
  Re: [long] Interrupt programming, buggy code
 
Hi Benjamin, When you declare your ISR as an interrupt_handler, GCC terminates the function with an "rte" instead of an "rts". The ROM code that dispatches the interrupt to your function is already doing the rte so your function should not. Here's (...) (21 years ago, 2-Mar-04, to lugnet.robotics.rcx)

(...) All I can give you is guesses. There are pleny of gurus here who will know the answer.

  RE: [long] Interrupt programming, buggy code
 
Having fun yet :-) There are a few things you might want to keep in mind when writing ISRs for the RCX... First, avoid calling into the ROM from an interrupt handler. You never know how long they take, and you may in fact be hitting another OCIA (...) (21 years ago, 2-Mar-04, to lugnet.robotics.rcx)
 
  [long] Interrupt programming, buggy code
 
Hi all, I am currently programming the Lego RCX at low-level (plain C) using the GCC cross-compiler for Hitachi H8/300 and Kekoa Proudfoot's LibRCX. In fact, I'm designing exercises for students that learn micro-controller programming. Therefore, I (...) (21 years ago, 2-Mar-04, to lugnet.robotics.rcx)
