i found this tutorial @ **broken link removed**

i tried it and it works, what if the switches are set to logic 0? what are modification needed in its code?

I'm presuming you mean the keys to +ve, and the resistors to gnd?.

All you need to do is replace the BTFSS lines with BTFSC in the 'Key Scan Process' routine.

its working...

thanks for answering a damn question...i'm really newbie and want to be an electronic god soon like you and other experts here.

this led flasher is really cool...i already tried the original circuit and also altered the reading switch to logic low...now planning to modify the ciruit to further test and do experiments...still reading switch logic low...porta are set as input mode...rb0 is txport...i want to experiment on: when button 1 is pressed an output " Switch 1" will echo in hyperterminal. etc.

how will be its initialization in a program?
