I am trying to build a motor (hobby servo) controller using a PIC 16F84 and Hi Tech C. I have struck a wall trying to get software UART working on my 16F84. I am trying to use some code (attached) that I downloaded from http://www.workingtex.com/htpic/ which I have found to be an excellent reference site for a beginner like myself! The problem I am having is that when I try to compile my project I get the following error message. serial.obj:12:multiply defined symbol: _getch (coms.obj) (error) serial.obj:12:multiply defined symbol: _putch (coms.obj) (error) I have a feeling it is probably something really simple and I just haven't figured out this compiler yet ;-) Thanks for any help and suggestions, regards James Fitzsimons Attachment Converted: "C:\APPS\Eudora\Saber5\Attach\serial.c" -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
