I am trying to convert linuxpp(david tait style hardware) from the 16f84 = to the 16f87x.... What would I have to change to make it work?? I saw that BAJ said = that(http://piclist.com/techref/microchip/16F877/taitlinux.htm): "The final patch to picprg 2.2 is changing the 0x08 begin programming = command in lowlvl.c to 0x18, which is the 16F87X equivalent." I tried that but it still couldn't erase my new 16f876... Any suggestions? YES, RB3 is tied to ground! andy -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
