hello, I finally the silly to work. All the test all concluent. just one thing, it do not recognize any PIC in the zif, I tried these command pic_ctrl -vpp 13 and they work fine, led blinking and all. I tried a second PICF648a, PICF84a, PICF88: Here is he message: C:\embedinc\com>pic_prog Firmware is type EasyProg version 18 by Embed Inc. Unable to read the device ID from the target chip. This is probably because the target chip is not a supported type, does not contain a unique device ID (12 bit core devices), nothing is plugged into the programming socket (if present), or the programmer is not connected to a target circuit. *** Program aborted on error. *** ken __________________________________________________ Do You Yahoo!?
