| + | '''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. |

| + | 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 having a Therezyn? |

| + | '''ADS1115 (Analog Input):''' It uses I2C address 0x48. The 4 analog input pins are labelled as ADx on the Zynaptik's header schematic. |
| + | |
| + | 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. |

| + | '''MCP4728 (Analog Output):''' It uses I2C address 0x60. The 4 analog output pins are labelled as DAx on the Zynaptik's header schematic. |
| + | |
| + | It's currently unimplemented in Zynaptik library. Would you like to do it? The highest honor is deserved to the brave who kill this dragon ... |
