I'm using GPSIM (version 0.22.0) and SDCC (version 2.9.0) in antiX Linux M8.2. I'm going through the exercise in http://www.micahcarrick.com/04-25-2005/pic-c-programming-linux.html . Everything seems OK when I run and step through the code except that I can't see the green arrow in the source browser for the C code, but I can see the port b1 arrow in the breadboard image alternate between red and green. In the previous exercise involving Assembly language code, the arrow showed up in the source browser like it was supposed to. Is there some simple thing that I have configured incorrectly? I can make a screenshot and send it to you individually if you're interested. (I don't think I'm allowed to send attachments to this list, and I don't think most people would like it if I did.) I'm hoping that one of you has resolved a situation like this before and can shed some light. It's just one little thing - I can't see the arrow pointing to the line in the C code being executed. -- Jason Hsu http://www.jasonhsu.com/swrwatt.html http://www.jasonhsu.com/swrwatt-c.txt http://www.jasonhsu.com/swrwatt-asm.txt -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
