Has anyone used a JDM/Ludipipo programmer (Mine's an18 pin version put designed by Silicon Chip and sold by Dick Smith Electronics in Australia) to program a 40 pin PIC ? In my case, a an 18F452? I've been using a breadboard and jumper kit to make the following connections; Name 18 Pin 40 Pin MCLR 4 1 VSS 5 12 & 31 Clock 12 39 Data 13 40 VDD 14 11 & 32 OSC1 15 13 OSC2 16 14 Attempting to use IC-Prog set to program an 18F452. However it chews up 100% CPU and takes about 5 - 10 minutes to program (over a serial connector). And at the end of it, after another 10 minutes at 100% CPU, it reads back empty (Code protection is off). Is it possible to program the 18F in such a way? Am I missing some connections? I'm after a "no extra parts" programmer (for lack of a better term) until I pick up a new programmer. -- "I went to the hardware store and bought some used paint. It was in the shape of a house.
