PICKIT2 on MPLAB IDE or Piklab or any other IDE for development on a PIC18F2620

Welcome to Microchip marketing. I bought a Pickit2, a while ago, to perhaps replace my clunky old serial EasyICD2 programmer. They advertised it as being able to program and debug "a selection" of their chips.

It turns out that their idea of "a selection" was exactly two processors. (It programs a few more than the two it can debug, but the selection is very limited.)

After selecting Pickit2 as your programmer in MPLAB, go to the Configure > Select Device menu. If the Pickit2 button is red, you're out of luck for your particular processor.

These days, I only use the Pickit2 for 12F683 projects. It seems to work OK for those. For anything else, I set up my EasyICD2.

Thanks Tom. I found that it's quite tricky to know that I have to configure the microcontroller in the devices configuration before I realized that the only microcontroller it supports is my PIC16F690. I have already contacted Microchip about it. Looks like I would have to try the open source way or try to complete my SD card data logging project on PIC16F690.

Stanley, it looks like I spoke too soon. I just checked the most recect device list for the Pickit2:

In the 7.62 MPLAB release, they've added both programming and debugging support for a whole lot of new devices, including your 2620 and the two 18F chips I use most: 1320 and 2431.

I just downloaded and installed 7.62. When I get a moment, I'll see if they speak the truth.

I recommend that you upgrade your MPLAB installation. You might be in business!

Thanks for the inspiration to check it out. It's been on my to do list for a while now, but I've kept forgetting about it.

Good luck!

BTW, Stanley, a number of folks on the RevEd Picaxe forum have been talking about SD card interfacing lately. When you get your app running, I'm sure lots of people over there would be most interested in your method.

Although it's not on my to do list, I'd like to learn how to handle these things, too.

Thanks!

I had a similar experience, worked fine with the demo board but wouldn't recognise a 16F877A, but found a way to get it working. Can't remember exactly how (sorry to be so useful) I think it was reloading the PIKIT2 Operating System or something like that. Definitely had to re-install something, but only had to use the menu buttons, so it wasn't anything too complex (can't have been for me to manage it!) All worked OK with not-latest-MPLAB as well. hth Neil

OK, Stanley, some good news and some bad news.

I was able to program an 18F1320 OK. However, I was unable to debug it, even using the pulldown resistors mentioned in the Pickit2 Readme file. I tried powering the chip from the Pickit2 or on external power. No joy.

I'm out of time at the moment, but I'll try again later.

In any case, it looks like you'll be able to use your Pickit2 to program your chip, at least, if you download and install MPLAB 7.62.

Best,

Tom

Hi Tom,

I've been able to erase and program my chip at least, although I haven't tried it with an actual sample code/project.

Cheers,

Stanley
