I'm trying to use the Arduino DUE to create some digital sound effects, utilising Due's DSP capabilities. The first objective is to create an Arduino shield with ADC and DAC connected to the microcontroller.
Data Converters / Analog to Digital Converter ICs (ADCs)
Data Converters / Digital to Analog Converters (DACs)
Amplifier and Linear ICs / Operational Amplifiers
I'd call it ADAC v0.1. I was looking at the Arduino DUE pinout to select proper pins to connect my ADC and DAC to. FInally connected them both to the pins of PORT C — it's 32-bit port, so I've used only about a half of it.
Board design prepared to be ordered, I'll be able to assemble v0.1 very soon!
I'm currently in the 'creating schematic' stage. I've breadborded the input preamp stage, tested it. Read the ADC and DAC datasheets, took recommended schematics from there.
Today schema is finished (current version look like this) so I've started designing a PCB. I hope to finish it this week so I can order the PCB from manufacturer, get the missing parts at weekend and assemble the board at the next week.
