PBP Support for 12F1840 8-Pin Device?

[springtank]

Greetings - I've been using PBP V2.50/V2.60C for about two years, mostly with 16F886 devices. I would like to try the new Microchip 12F1840 8-pin part, but it is not listed as a supported device when using MicroCodeStudio and PBP V2.60C. Do I need to wait for another PBP patch before I can use the 12F1840 part? Not sure what to do.
Thank-you for making this forum a wonderful resource.

The 12F1840 is not even in production yet.

Microchip is sampling them, but that's all.
Production quantities are expected by late July or August.
We just got samples a couple days ago.

They will be added to PBP in the next version.

Darrel - Thank-you very much for the reply. I ordered and received some 12F1840 devices from Mouser back in mid-April, so I didn't realize they were not in production. No worries, I can wait, and at least now I know support is coming for the part. You rock as always.

I emailed PBP support re this matter a few weeks ago and they replied that they though code compilied for another pic would run on it. I will post details later I don't have access to it here. I think the issues were that the suggested pic has more ports, so as long as you didn't try to use them then hex code for the substitute pic may/should work on the 12F1840.

I also spoke to piccircuit .com who make a neat cheap pickit 2 clone and they sent me a file to allow the pickit 2 software to work with the new device.

I'll post details later.

The datasheet wasn't available in time for our last PBP revision, and another revision isn't planned for few months.

It looks to me like the part is identical to the 16F1828, with the exception of a few missing ports. I think you can compile for the 1828 and the hex file will work for the 1840. Let me know if you encounter any compiler or assembly errors and I will look into it.

Programming support for the 1840 has already been added to the meProg software for the programmers.

Hi,

Thanks for checking with us.
For the PIC12F1840, you might need to install the attached patch to enable the PIC12F1840 programming
Please apply the patch at C:\Program Files\Microchip\PICkit 2 v2>PK2DeviceFile.dat
Then the PIC12F1840 should be detected by the PICkit2.
Please let us know the testing results on our solutions. We will try our best to help you.

Best Regards,

Retepsnikrep (Peter?) - Thank-you for taking the time to post the added info. When I get my test board together, I will certainly give it a shot - Very much appreciated.
