Hi, I want to build a stand alone programmer, using a 16F628 for example, = for programming a 16F627 and a 12C671, and both images should be inside = the 16F628 who acts as a programmer.=20 So, before starting, I have a question: Which difference is there in programming each one of these micros, = which have the same amount of program memory ? Obviously I know about VPP on 12C671. So, if I have the 2 images (they=B4re small) inside the 16F628, could = I program both using exacly the same algorithm ? And what about 16F84 ? Is it the same, too ? Thanks to everyone !! Gabriel.- -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
