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.
