Hi, I'm new to the PICList. I am currently employed with an efficiency engineering firm in Tempe, Arizona. Recently I was assigned the task of redesigning our line of photovoltaic charge controllers to implement the PICMicro. To do this successfully I will have to become an expert at the PIC very quickly. My background is in Materials Science and Engineering, though I have a fair amount of experience in microelectronics and computer Programming. Despite this, I lack any experience with Assembly coding or microcontroller application. My initial experimentation with the PIC16F84 includes building an El Cheapo programmer, which works, and some small, simple LED and LCD circuits to test my programs. My problem, however, is that I am unable to perform a BULK ERASE operation. My lack of assembly experience and the esoteric instructions in the programming datasheet are holding up further development so I turn to the PICList for support. Can someone please, in plain English and Assembly explain how to perform a BULK ERASE on a PIC16F84(A). I would really appreciate it. Thanks!
