SigmaStudio can communicate with hardware in real over a USB connection. DSP Program Data, Register Settings, and Parameter control data is sent to a USB device, converted to either SPI (serial peripheral interface) data or I²C data, and sent to the SigmaDSP hardware. It is also possible to read hardware register values via USB.
When using an evaluation board with integrated USB connectors, locate the Communication Channel block with the corresponding SigmaDSP part number. For example, EvalBoard170x should be used with the EVAL-ADAU1701EB and EVAL-ADAU1702EB platforms. Connect a USB cable directly to the evaluation hardware and to the PC.
There are also two generic communication channels available:
See your evaluation hardware's data sheet for more information, www.analog.com/sigmadsp.
The proper USB drivers must be installed to communicate with SigmaStudio. To setup the USB hardware:
The color of the USB label on the communication block indicates if a USB connection has been established. If the USB hardware is properly configured, the background color will be light orange or white. If the communication is not properly initialized the background will be red. Note that this only indicates that a USB connection is active, it does not guarantee communication with the SigmaDSP IC or that the SigmaDSP hardware is properly configured.
The “Connected” background color is white when all board ICs are connected, and orange when only some ICs are connected, but not all. For example the ADAU1701 evaluation board includes both an ADAU1701 IC and an E2Prom IC. When connecting only the ADAU1701 the background will be light orange, but it will be white when connecting both an ADAU1701 and an E2Prom IC.
