Hi. As a newcomer to pic's and microcontrollers in general, Im hoping there is a WEB resource somebody can point me to to help me out. Im having trouble understanding, and using, the hardward SPI interface on the pic 16C64/74, as a master, with slave SPI interfaced devices. (in this case, an ISD sound chip). A few snippets of code is probably all I need to help me "grok" the mechanics of it. Many thanks. Tony. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
