>> I have searched the www.microchip.com site and found only one (1) appnote for 16F877. I am learing this processor so Id like some simple example to study. Like code and schematics.. I kinda thougth microchip would have atleast a few examples. I'd like som suggestions on where to find more info/appnotes about the 16F877 mcu. << I have the source code for a 16F876 project at http://www.embedinc.com/pic/hal.htm. The 876 is just like the 877 except that it has 28 pins instead of 40. From the program point of view it just has a few less I/O bits and A/D channels. In fact, this code should run without modification on an 877. ******************************************************************** Olin Lathrop, embedded systems consultant in Littleton Massachusetts (978) 742-9014, olin@embedinc.com, http://www.embedinc.com -- http://www.piclist.com#nomail Going offline?
