MIDI Stop Controller V1.0 suitable for driving Hauptwerk digital organ software. Written for the KL25Z uses BusInOut and will drive up to 16 illuminated push buttons each switch uses a single I/O pin to both drive the LED and act as a switch input. Pressing a button will alternately send MIDI note on / off messages and turn the LED on or off. If corresponding MIDI note on/off messages are received these will be used to drive the LEDs in preference to the locally generated LED signals. The MIDI channel used to send can be selected by jumpers on 4 pins of the J2 header.

+// LED connected to +V via ballast resistor, switch shorts output to gnd which is read when the bus is in input mode.
+// White LEDs need a 390ohm resistor to +5v other LEDs can be driven from 3.3V via 220 ohm resistor or 5V via 680 ohm.
+// The above values provide the maximum current that a KL25Z can sink namely 4mA per output.
+// Every 2ms the LED bus is switched to input in order to read the switch status then immediately switched back,
+// this is not noticeable as a flicker on the LEDs. Buttons need to be pressed for 2 scans to de-bounce.
+// The program will toggle the LEDs sending MIDI on/off messages, if Matching MIDI on / off data is received this data will be used
+// instaed to drive the LEDs.
+// The blue LED on the KL25Z will light while the USB port is initialing
+// The green LED on the KL25Z will flash as MIDI messages are received.
