Not being one to take good advice when given some, after realising the miner_pic.hex file was an ASCII file, I decided to deploy my secret reference material (read google) and seem to have found something, though I can not make any sense of it. I am sure bitsolutions, the clever clogs on our side, can so here goes.
1. My reference material suggested a site to view a hex file: http://en.webhex.net/
On visiting the site, I browsed to the file and uploaded the miner_pic.hex file
2. On the next screen, I scrolled to the bottom of the box and clicked on the Export link
3. When the Export screen was loaded, I un-checked the Headline, Offsets and Readable Characters check-boxes then clicked on the Export button on that screen.
4. I was then presented with the hex data in a web page. I had not mentioned this, but earlier, my reference material had also suggested to me an online dis-assembler here : http://www2.onlinedisassembler.com/odaweb/
5. I copied all the exported hex data (Ctrl + A then Ctrl + C) then flicked over to the dis-assembler, clicked on the Platform button and changed it to avr (this may b wrong), and in the box below that I pasted the hex data into it.
The page then did a little spinning wheel and after a short while, spewed out something like this:
Now the easy bit, @bitsolutions or any of you clever clogs out there, can you make any sense of that?
