Use mplabfor 16f88
I gave up trying to program the 16f88 with the pickit2 application program. Just use the mplab ide and select pickit2 as the programmer. I was able to program the 16f88 just fine with MPLAB. I used the same ic in both cases, so the ic is ok. I don't know what the problem is, but I need to get back to work.

I have gotten that error too, and when it does so it usually sets code protection too!Originally Posted by botsmaker

The fine print in the pickit2 docs say to reselect the chip ( select another pic and then reselect the one you are using) and then write the chip without selecting a hex, then select your hex and write.

Pickit2 programs now
I went back to using the pickit2 with the 16f88 and now it will program. Still get a "hex file not loaded error", but at the end of programming I get the green box.
The problem is intermittent. I got less failure when running power of the board instead of powering through the pickit2. In other words, it always programmed.
I did manage to build my own 4 digit meter with a 16f88 and PBP using some of the example code at MEL about driving led displays. This meter will display from 0 to 100.0 volts if you use a rail to rail opamp instead of the LT1077 I got in it now. Below are links to drawing and code.

Back when I was using a PIC Start I had to add a couple of capacitors across VDD-VSS or it would not program some of the 18Fs.The problem is intermittent. I got less failure when running power of the board instead of powering through the pickit2. In other words, it always programmed.
Maybe a similar problem???

Meter Photo
I added a photo of the meter at my profile album. I designed a pcb to make up the circuit and had Expresspcb make it. The board can be configured into a frequency counter or event counter. Just load a different program for a new function. Its a multipurpose board. You can also bring out the ports through a 16 pin ribbon connector instead of a 4 digit display.

Looks like a useful piece of work! I like the dual function idea.
