− | '''+ Secondary MCP23017 (Digital I/O):''' It uses I2C address 0x21 and the 2 interrupt lines are connected to the RBPi GPIO. INTA to GPIO27 (pin 36) and INTB to GPIO25 (pin 37). The digital I/O are labelled as GPAx & GPBx on the Zynaptik's header schematic. | + | '''+ Secondary MCP23017 (Digital I/O):''' It uses I2C address 0x21 and the 2 interrupt lines are connected to the RBPi GPIO.

− | Currently you can use it for adding more switches (yet!) to your zynthian. There are plans for integrating the HC-SR04 (Ultrasonic Distance Sensor) and using it for controlling parameters (MIDI-CC). Would you like to be the first one having a Therezyn?
| + | You can use it for adding up to 16 extra switches to your zynthian. |

− | The Zynaptik library currently implements a mechanism for assigning the Analog Inputs to MIDI-CC. This can be used for connecting CV-IN or for controlling sound engine parameters using analog sensors.
| + | You can assign the Analog Inputs to MIDI events like Pitch-Bending, CC or ChanPress. This can be used for connecting CV-IN or for controlling sound engine parameters using analog sensors. |
