Ciao at all of you, I'm 3 week old novice of PIC and have became an entusiastic of 16C84. As a case study I have decided to buid a RPM bar LED indicator for the motorcycle (like copy in progress indicator). Up to now I have encountered the tipical problems of the new processor that can be solved trying and testing, but now I have a sensation of frustration and impotence. Now I'm in trouble because I need to compose a routine like "case" or the tipical; " IF TMR0 >= 196 GOTO AnyLabel ELSE GOTO OtherLabel". From my local MICROCHIP distributor I have obtained the last CD ROM "1997 TECHNICAL LIBRARY SECOND EDITION", and I have printed out the 156 pages of "MPASM USER'S GUIDE" and under chapter 6, on page 75 I have found all instruction that seems very useful for me. (multiply, divide, less than, etc), but no words about the use of it. (Probably my bad english contribute in missing understanding). Looking on all routine that i have the opportunity to see, no macro one use of this operators. Why? I would like understand how build a macro using the aritmetic operators. I think this list shoul be the better place to discuss about this argument. Can someone illuminate my darkness. Thank in advance at all of you Saluti leo.depalo@telesys.it
