Seriously, folks, see all this information with full colour pictures, step-by-step instructions and much more on my GitHub:

So we're looking at the 32MHz Nano-sized drop-in replacement but I'm using a different sized development board just for ease of use in the video. My device looks like this (and well worth it for experimenting with)

But the final device is Nano sized, and a drop-in pin replacement

Or you can have a Pro-Micro sized device that will require a USB-to-Serial adapter to program.

The 6 simple steps to get a LGT8F328P-based board running at 32 MHz are listed on my GitHub.

6 Simple Steps to get a LGT8F328P-based board running at 32MHz
*1 Download the LogicGreen zipped resources here*
github.com/LGT...
There's a copy of this zipped folder on my GitHub
*2 Extract the download (unzip it)*
and move the unzipped LGT/avr folder to under the hardware folder in your Arduino sketch folder. If you do not have a hardware folder in your Arduino Sketches folder, just create one.
Your structure should look like this:
github.com/Ral...
*3 Replace the boards.txt*
In the Hardware - LGT - AVR folder **delete the boards.txt**.
Then copy the boards.txt in this GitHub there in place of the one you just deleted. Easier than trying to edit it!
Testing

Oh no! I've exceeded my RUclips word count so head on over to my GitHub to complete the process!

What's this GUID then?
Each LGT8F328P has a unique GUID (serial number) built in. Useful for encrypting things.
To retrieve the number (it's read-only) do this in your sketch setup():
uint32_t guid = *(uint32_t*)&GUID0;
To display that number in its intended *HEX format* do this:
Serial.println(guid, HEX);
Simples, right?
