Since the MIDImerger project is still quite popular, I created a new variant which is based on the PIC16F88.

Not only that this chip is smaller and cheaper - it's especially possible to use it without external crystal with a sufficient accuracy :)

Thanks TK, I was just thinking about a merger. This will be a good reason to build a pic burner.

Is it possible to program the 16f88 with (JDM + (PicBurner 18f452 to 16f88 adapter) + icprog)compatible with 16f88?

I see MBHP burner is compatible, but I have already built the JDM module a long time ago, with many succesful burns of 18f452.

Thanks a lot

Note that it has been made for the DIP40 devices, a layout for the newer (and cheaper) PIC16F88 based circuit is not available yet.


Something like this?

WOW nils that was lightning FAST!!!!  :o

:D

I was studying the possibility of programming the 16f88 with JDM, and as far as I can see, all of the needed pins in 16f88 are supplied by JDM. Is that enough for JDM to be able to program it? Btw, ICProg has 16f88 in its list.

I wonder... can it support an arbitrary number of input jacks?

no - for more inputs you need something like the MIDI Router project

Thanx, tilted. Yes, I was talking about that adapter when I said JDM + adpater. So, it works both for mbhp burner and JDM burner?

Good!

Just as a commentary: I can't seem to find 16f88 at the stores here. It's far easier to find 18f452 or 16f877... I suppose 16f88 is a newer MC?

Thank you Nils, but where are the PCB files?

Right here on my PC. I should have added: PM me, if you're interested. I'll give them them some final touches and possible publish them here (if it's okay with TK)

I`m not in hurry. I just thought I don`t see it. Do the final touches. ;) Thank you very much for your work.

Fantastic!  Now, I just have to figure out what box to put one into!  I foresee a MIDImerger with an 8x output driver in my future  ;D

The PCBs are look fine, thanks Nils! :)
I will put the layouts on my website once the boards have been successfully tested by someone

Best Regards, Thorsten.

I *think* they're done. They still need to be tested by someone. I don't really need the merger just yet, so I won't get around to testing them anytime soon. There's also a layout sketch for a perfboard variant in the .zip file.

That's what they look like:
