Hi.. A friend of mine helped me out with getting a 7-segment display interfaced with a max7219. The code and circuit work fine.
I'm now trying to expand it's usefulness - I wish to add a temperature input.
So, I thought it would be easy to display the decimal point - but not so.
I've racked my brains and read through the entire forum and can't figure it out.
I'll post the code..
Please let me know what do change..
THanks.
