> I'm just curious if anyone here has had any experience with using RTL8019 chip? > If I purchase this chip and mount it on my own pcb will the RTL8019 require any programming like a PIC, or is it a pre-programmed chip that I can interface directly to a PIC with minimum effort? I don't know anything about this chip, didn't you find such basic answers when reading the data sheet? That's the first thing I would do if I had such questions. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The PICList is archived three different ways.
