Hello, I'm looking for a good 16 keys keypad scanning routine. I would like it to work using interrupt on change on port B. Anyone could point me out to such a routine ? I did some research on the net and haven't found anything. Hope to get some feedback. ------------------------------------------------------- 73, AndrŽ VE2WNF > Contact me at: E-Mail1: ve2wnf@amsat.org E-Mail2: ve2wnf@ican.net E-Mail3: ve2wnf@geocities.com E-Mail4: ve2wnf@qsl.net EmailExpress: 2588656@pager.mirabilis.com Via Packet: VE2WNF @ VE2CSC.#MTL.PQ.CAN.NA Visit me at: URL1: http://www.geocities.com/SiliconValley/Vista/9500 URL2: http://www.qsl.net/ve2wnf URL3: http://wwp.mirabilis.com/2588656 -------------------------------------------------------
