Post by thread:question about PLL+ freq input

Hello picers, I want to make a program for the PIC16f84 to control a PLL. It has some user input keys, and needs to clock out the stream serial (no probs). Does anybody knows how to convert (in the code) the user input in MHz/KHz to the serial bits needed by the PLL. See it as follow: bit 1 = 512 MHz (it stays on 0) bit 2 = 256 MHz (it stays on 1) bit 3 = 128 MHz (it stays on 1) bit 4 = 64 MHz ( depends on user input) bit 5 = 32 MHz ( "" ) bit 6 = 16 MHz ( "" ) bit 7 = 8 MHz ( etc ) bit 8 = 4 MHz bit 9 = 2 MHz bit 10 =1 MHz bit 11 = 64*12,5KHz bit 12 = 32*12,5KHz etc... Any help is welcome!!! Thanks in advance, Joep Schroen (pd3rog)
