I recently bought a bunch of 12LF1552 chips to play with the built in CVD vs. the purely software mtouch framework.
I quickly found that my old Pickit 2 would not work with these chips, so I purchased a Pickit 3.
For a test of the new Pickit 3, I thought I would load an already working hex file into a 12F1840, which was the last program I did using the Pickit 2.
When I connect the chip up to the Pickit 2 it immediately knows all about it. Easy to load the hex file and program the chip.
When I try to use the Pickit 3, it has no idea what the chip is, and it's not in the limited device list it provides. I loaded the latest software for the pickit 3 that I could find, dated 6/11/2013. The about shows "Application Version 3.10.00, Device file version 1.62.15, OS Firmware version 2.00.05
Still no joy. I can unplug it, plug in the pickit 2, load the old pickit 2 software, and it loads the 12F1840 hex file and programs the chip with no problem.
The Pickit 3 has no idea what this older 12F1840 chip is, much less the newer 12F1552 chip.
I would greatly appreciate any help getting new Pickit 3 working.
p.s. - For the sake of clarity, assume I use a third party software to produce the hex file I want to copy to the microcontroller chip.
