CHANGELOG

CHANGELOG:
Version 0.1.7:
Main:
Decided to try and comment changes better.
This at least gives a minor insight in to why I did it. I'll mark comments added later with an asterisk.
Software:
Practically rewrote the main loop.
Instead of all the switch/case bullshit, I just dump to a variable and make that part of the
conditional IF statements.
Bitmapped the logo.
Fonts are large. The 98x24 bitmap was smaller.
Version 0.1.6:
Software:
Removed a bunch of functions in favor of passing arguments to function.
The indvidual functions for setting each input and setting the LCD have largely been combined
in to one since I figured out how to use arguments. Additional stuff changed/added to accomodate
this.*
Version 0.1.5:
Hardware
Removed 2003 ground from 595 enable line. (That was a stupid idea that thankfully didn't blow up.)
I calculated the relays to be 40mA each. Sinking that much current from an IO pin is pushing it, let alone
the fact I need two relays for phono inputs.
Added logic invterter to drive the 595 enable and 2003 ground. (Transistor can sink more current).
The 2N2222 is rated for like...800mA or something; wayyyy more than I need. In retrospect, this would have been
a better solution overall than the reset circuit on the 595. Will I change it? I'll have to play with it.
Software:
Flipped srEnable logic to drive logic inveter added to board.
@ -21,6 +41,8 @@ Version 0.1.4:
Hardware:
Tied ULN2003/2803 ground to 595's enable line
Even with the shift register quiet during boot, the darlington array isn't; and pull-down
resistors don't seem to help. But I soon realize this is a stupid idea.
Replaced 1602 display with SSD1306 128x32 OLED

@ -14,6 +14,7 @@ Arduino Control for Your Vintage Stereo
04-Jan-2020: Version 0.1.4 - Changed project name. Removed 1602 display code. Added 128x32 OLED code
05-Jan-2020: Version 0.1.5 - Fixed stupid mistake in hardware. Flipped logic of srEnable for new circuit.
05-Jan-2020: Version 0.1.6 - Lots of code clean-up, condensing, rewriting.
06-Jan-2020: Version 0.1.7 - More code clean-up, practical rewrite of main loop. Bitmapped the logo.
