S.O.P. Track 10 - Brandenburg Concerto No. 3 In G Major-1st Movement

A major rewrite of the Arduino/Atari communication software was accomplished.  It seems the Cassette Motor Control pin causes a spike when it switched.  (You can hear it in some of the previous tracks.)  BIT 7 of PORTA has been configured for output.  Joystick 2 trigger can be used as BIT 7 if its ever needed.

 

It took a couple of weeks of software trouble shooting to figure out that the hardware was the problem.  The output power from the CMC was enough to trigger the optocoupler but the power from the joystick port was not.  A resister was changed and the software seemed to be working the way it should.

 

There still seems to be a click but is a little less noticeable.

 

Sorry, I wasn't going to get technical.
