Hi folks,

I've been using 16f819s for a while now and needed a smaller package for a space restricted installation, so I got a handfull of 12f675s.

I'm using PBP and the 4.x melabs programmer and putting a 4k7 to vdd for MCLR. Nothing else is being set specifically, except of course intosc, watchdog enabled, brownout enabled and powerup enabled.

The chip will not start. All I did to test it was put a 220 to a led from GP5, pretty standard test.

Checked voltages and led wiring and everything is as it should be.

Is there startup files that need to be included with this chip?

help?

Gary
