Hi Steve,

If you still have that MPLABS installed, please let me know the version. All I know is that Tracy said he could not get it to work with more recent version of MPLABS. I guess it was easier for him to revert to MPLABS 8.15 rather than figure out how to get it to work with newer version of MPLABS. I think he's using the "hockey puck" MicroChip programmer/ICE (ICD 2 or 3?)

No clue why Tracy upgraded to the 18F452. Faster? More memory?

Well, I had purchased the PICKit 3 and finally downloaded MPLAB 8.15.
Unfortunately the PICKit 3 is not a programmer option in MPLABS 8.15.

Did you you run into this and solve it?

I could:
1) Keep downloading and install more and more recent versions of MPLAB until PICKit3 appears as a programmer option (and hope that the version still works with Tracy's code)
or
2) Purchase a PICKit2

Attached are the chip configuration settings. In MPLABS, pick the settings listed on the right. Most are MPLABS defaults for the 18F452 chip, but a few need to be changed.

As for Sam's, Tracy did extensive modifications for Sam'scontroller that he now regrets having done. Sam would really, really be better off with a pair (for redundancy) of SpeedUino boards. Program them for a 4 cylinder Subaru and go from there. (What might be happening with the EC3 is that it has a startup timing setting and a running timing setting.

Oh, config for the particular chip used?

Again, I'm not (yet) familiar with the development and compiler to know what's required.

I don't understand what's so difficult about removing the chips from the board and programming them in a $7 socket connected to the 4 or so programming wires from the PICKit3.

Thats disappointing to hear.
I still may need to reprogram mine for (turbo or change in coils) so I???ll be interested in what others find.
I may need to go back to my EC2 which I can reprogram.

I don???t understand the config settings coming out of compiling the code.
Tracy previously provided the following config for the EC2
Osc                             EC OSC2 as RA6

Not sure how you would create the executable without these config data for the compiler.

Talked with Tracy today.

Yes, programming pins are carried out to the DB connectors on the EC3.
However, there has been some instances where in-circuit programming
didn't go well (he never found out why), so he recommends programming
the chips removed from?? the board (for example using the socket I
ordered). He mentioned that he could not figure how to get it to work
with more recent versions of MPLABS and recommends version 8.15 or so
(should still be available on the Internet
https://www.microchip.com/development-tools/pic-and-dspic-downloads-archive).
Need to confirm that the version that worked for him is indeed 8.15

The config file should be automatically generated first time you compile
the code, unless he's forgotten something.

Problem with Sam's version is he's forgotten the mental notes about the
differences between the rotary and the big bore aircraft engines.
Basically the EC3 is now old technology (the 18F452 chip considered
obsolete) and recommends using readily available Arduino-based engine
controller boards.

Gave the example that even though the plans still exist , no one could
build a Saturn V rocket today, because the engineers and their notebooks
(mental and otherwise) on how to actually build it are gone.

Regarding reading and understanding the code, remember that it is
interrupt-driven and not just one long series of sequential code.

I hope I've properly understood and relayed his comments here.

Hi Fin
Sorry. I missed your photo, but found it just now. Yes, appears no headers!
So we need a circuit diagram. Pins 16 &17 (PGD and PGC) of each processor would need to be accessed for in circuit programming me thinks.

I thought I'd posted a picture of the EC3 on 12 June.

Trying again.

There are no header pins.

I only spent a few moments on it but the version of MPLABS I have didn't accept the PICkit3 for programming the
18F452 processors which appears in Tracy???s notes as the EC3 processors.

Have you looked inside your EC3? Are there 6 pin ICSP headers for in circuit programming like he EC2?

Would like to hear from Tracy or someone else that has experience programmed the EC3.
We also need the config data for the compiler.

I hope that's not true. What makes you think that?

I just ordered https://www.ebay.com/itm/262583587324
and https://www.ebay.com/itm/273846534119
I figured I can connect the 6 wires directly to the DIP40 pins, bypassing the DIP40 socket.

I still need to download MPLABS andget familiar with that, but that's several weeks in the future.

Hi Fin

Ive spent a few moments looking at the EC3 code.
I???ve previously updated the settings of my EC2 using the method discussed previously, using MPLABS and a PICkit3,
however having looked at the EC3???s processor details I???m not sure if it can be programmed with a tool like the PICkit3.
I???ll need to look further into this.
I???m hoping Tracy might be able to enlighten us re programming the EC3 processors and the config settings required.

Does anyone else have the details re programming the EC3 etc.

See pdf of an EC2 circuit board showing in-circuit programming headers. The EC3 will be similar.

What is a 6-way header?

I wonder if the above programmer will work with MPLabs (a 744 MB download!)

I use a PICkit 3 programmer which I imagine are about $50USD.
This plugs into the 6 way (from memory) headers along side of each of the pic processors.
