Over the weekend, I think my exploration of Linux as a MCU and electronics development platform has made a significant progress. Please refer to my other post on the PIC development tools support ([PIC] PIC development under Linux with Wine). 1. Linux environment: Ubuntu 5.04 Hoary + Winetools from Winehq. (http://www.winehq.org/site/download-deb) 2. Status on Spice circuit simulation program: Please note I have not done a thorough testing. 1) LTSpice works quite nicely. 2) PSPICE 8 demo version works as well. Just take note that you need to invoke using the -i option. (psched -i msim_evl.ini) in order to correctly loading the library. 3) ORCAD 9.1 student edition works as well. I've tried to simulate circuits with both Capature and Schematics. 3. Status on AVR development tools As a side note, I tried to install AVRstudio under Wine. AVRStudio 4.11 installs okay but does not start. AVRStudio 3.5 installs okay and seems to work as well. Since I do not have any AVR hardware and I am not that familiar with AVR so I have not done any test yet. Ironically Winavr 2005.2 does not install under Wine. However since we have all the GCC-AVR tools working under Linux. Therefore it is not a problem. So people interested in AVR on Linux are luckier.
