Hello! I need to have a PLL with a PIC (such as PIC16F84A), could you provide = me an example code (in C...) to do this ? I wouldn't use an extarnal = chip to realize PLL.... The frequency I want to lock is 2400 Hz (for meteo satellites.....). Any suggestions are welcome !!! thanks bye, Marco Trapanese --- e-mail: marcotrapanese@tin.it web: http://members.xoom.it/m_trapanese -- http://www.piclist.com hint: The PICList is archived three different ways.
