Hi, I am looking for a development board for DSP on a realtime analog audio signal. My requirements are as follows:
-Onboard audio codec with stereo input and output, with example projects for setting up audio callback
-Access either to on chip ADC pins, or on chip SPI interface (for use with MCP3208), via header for reading potentiometer values
-Access to on chip GPIOs via header, for reading switch values
-At least 128kb of on chip RAM, 256kb or more is preferable.
Is there anything y'all can recommend which fits these requirements?
