I am using the one I described in this forum post: http://forum.microchip.com/tm.aspx?m=264400 Pure Microchip based solution is a bit too complicated. Quote from the answer of the current PICkit 2 developer Walter: "There is the AC162049 Universal Programming Adapater that can be used with PICkit 2 with the AC164110 RJ-11 to ICSP adapter. One other item of importance is that the resistor R1 must be removed from the Universal Programming Adapter for PICkit 2 use, as the PICkit 2 VPP pin can't support the current to drive the LED." If you have problems with PICkit 2, you should visit the Microchip Forum and read the sticky posts on the top. http://forum.microchip.com/tt.aspx?forumid=15 Documentation about PICkit 2: http://www.microchip.com/pickit2 Xiaofan Xiaofan -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
