Hi Ted, The 4mhz version of worktime.asm is wktim4m.asm and is on http://www.piclist.org/techref/piclist/cheapic/index.htm half way down the page. The page has all the Beginner projects in 4mhz versions. >I have three 16x2 LCD displays that I picked up cheap so I decided to >build something real simple, really to prove the displays work. I chose >the worktime.asm program from the piclist source library - this is >designed for a 32,768 Hz crystal and uses the 16F84 . Only having a >4MHz crystal, a changed the timing routines to give me interrupts every >0.065536 seconds or 15.26 Hz. I've attached the .asm code for those who >are interested enough to look at it. > -- http://www.piclist.com hint: The PICList is archived three different ways.
