Just download Picallw v0.14b for my newly built Picall programmer, it = was working fine with v0.10 but with 0.14b if I enable SQTP the program = crashes everytime and if I restart it and load filename.hex to which = there is an associated filename.s_n it crashes, I have to delete the = filename.s_n file to get it to run again, anyone else had this problem? Also I've been using it to program 16f628's and notice the red LED VPP = comes on during programming which I believe puts 13v onto the MCLR for = programming, what does the VPP1 LED do? =20 Regards Neville...=20 Click Here To Visit My Home Page=20 -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
