Adding Extra I/O with the Zynaptik Module (view source)
Revision as of 00:32, 11 March 2022
, 00:32, 11 March 2022→Introduction
The zynaptik module provides:
The zynaptik module provides:
* 3 standard MIDI ports (IN, OUT, THRU)
* 3 x standard MIDI ports (IN, OUT, THRU)
* 16 x digital Input/Output
* 16 x digital Input/Output
* 4 x Analog Input
* 4 x Analog Input
* 4 x Analog Ouput
* 4 x Analog Ouput
'''New modules''' (from 2021-04-01) include everything soldered on. Ready to work:
Latest ''Zynaptik-3 Extended'' modules (from 2022-03-10):

In the other hand, '''older modules''' (before 2021-04-01) only have MIDI circuitry soldered on. You must solder some parts for enjoying all the functionality. You can [https://shop.zynthian.org/shop/product/zynaptik-expander-kit-379 buy the Zynaptik Expander Kit] or order the parts by yourself.

{{NoteBox|The ''Zynaptik-3 Standard'' module doesn't include the analog input/output chips (ADS1115 & MCP4327), including only the MIDI circuitry and the MCP3017 GPIO expander for connecting the 4 rotary encoders with switch.}}

'''+ ADS1115 (MOD-1 Analog Input):''' It uses I2C address 0x48 by default. The 4 analog input pins are labelled as ADx on the Zynaptik's header schematic.
'''+ ADS1115 (MOD-1 Analog Input):''' It uses I2C address 0x48 by default. The 4 analog input pins are labelled as ADx on the Zynaptik's header schematic.
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.
The voltage range is 0-5V. You can assign the Analog Inputs to MIDI events like Pitch-Bending, CC or ChanPress and use the analog signals for controlling any sound parameter. Analog Inputs can be combined with digital inputs from the MCP23017, allowing to configure up to 4 x CV/Gate-IN interfaces.
'''+ MCP4728 (MOD-2 Analog Output):''' It uses I2C address 0x60 by default. The 4 analog output pins are labelled as DAx on the Zynaptik's header schematic.
'''+ MCP4728 (MOD-2 Analog Output):''' It uses different I2C address (0x60/0x61/0x64) depending of the zynaptik model. The 4 analog output pins are labelled as DAx on the Zynaptik's header schematic.
The voltage range is 0-5V. You can assign MIDI events, like Pitch-Bending, CC or ChanPress, to the Analog Outputs. Analog Outputs can be combined with digital outputs from the MCP23017, allowing to configure up to 4 x CV/Gate-OUT interfaces.
