- has a dual-core DSP56725 ;)
- Stereo analogue input
- Stereo digital input
- 8 analogue outputs with analogue volume control
- 10 digital outputs (8 of them carry the signal of the analogue outs before DA conversion)
- 2 I2S expansion ports
- 48kHz, 96 kHz and 192 kHz are all 3 natively supported by the DSP and that sampling frequency is user selectable while configuring the board
- the ability to view a final response graph, overlaid on a target response curve
- the board has over 1s of delay (at 96 kHz) to share between the channels
The board also features headers for keypad with 8 push-buttons, LCD, status leds and IR sensor as well as a USB connector for the control application. Peripheral management is performed by a micro-controller so that the DSP stays fully available for DSP routines.
Also, in order to have the main board operating, you'll need first to provide:
- a power supply (5V and +/- 12V)
- a back-lit LCD display - any color any size provided it's the proper type (2x16)
- 8 push-buttons
- a IR sensor (5V 38kHz) if you intend to use a remote controller, which I recommend.
It's going to be cheap and very good quality.
I hope to make available the hardware and the Windows build in 3 months.
