dsp.coffee DPT - Multifunction Electron Temple (Daisy Submodule DSP Platform)

Our custom everything-including-kitchen-sink dsp development platform.

At the core of this is an Electrosmith Daisy Patch Submodule, combined with a 12-bit 4 channel SPI DAC [DAC7554], and supporting hardware for more IO.

Features

• 8 pots normalled to +5V.
• 8 CV in breaks normalled connection and pot acts as an attenuator.
• 2 gate in
• 2 gate out
• High fidelity stereo in/out (Daisy Patch Submodule uses an WM8731 codec).
• 2 12-bit CV out from Daisy Patch Submodule, scaled to -5v to 10v
• 4 12-bit CV (or lofi audio w/ some hacking) from external DAC7554, scaled to -7v to 7v.
• TRS MIDI in/out (MIDI in uses lpzw auto-sensing circuit for A/B)
• SD card slot.
• Has an expander header on the back for +5v, +3v3, SPI, UART, I2C, and USB connections. (UART, USB, and i2c can be used as GPIO, UART can be used as ADC9/ADC10).

This is very much developer oriented, so you have to be comfortable with uploading and/or compiling firmware to get the most out of it. Also, firmware is under active development.
