Arun Kumar V<nura1002003@nospam.com> http://www.8051projects.net/forum-t10130.html H Arun, Can u please explain it in PIc languague (ASM)because i dunno about the language u used ...sorryi wan to INCF a register to 255 or DECF to 0 nicholastyc<thamyc_2000@nospam.com> http://www.8051projects.net/forum-t10130.html hi arun,thanks for pointing out my errors actually i noticed it too so i added the last statement. anyways nic needs it in PIC for which i am as new pdi33<islurpundalik@nospam.com> http://www.8051projects.net/forum-t10130.html nicholastyc wrote ...H Arun, Can u please explain it in PIc languague (ASM)because i dunno about the language u used ...sorryi wan to INCF a register sashijoseph<sashijoseph@nospam.com> http://www.8051projects.net/forum-t10130.html thanks for info...i really having problem for the encoder part...i try to use incf and decf and then btfss/btfsc STATUS,Z to check for the max 255 and nicholastyc<thamyc_2000@nospam.com> http://www.8051projects.net/forum-t10130.html actually u people are working on assembly...i didnt use assembly for years so cant help on asm parts..have interfaced encoder on lpc21xx controll shyam<shyam@nospam.com> http://www.8051projects.net/forum-t10130.html
