+	bool "I2S character driver test"
+	default n
+	depends on I2S && AUDIO && AUDIO_DEVICES && AUDIO_I2SCHAR
+	---help---
+		Enable the I2S character driver test
+
+if EXAMPLES_I2SCHAR

+config EXAMPLES_I2SCHAR_DEVPATH
+	string "I2S character device path"
+	default "/dev/i2schar0"
+	---help---
+		The default path to the I2S character device. Default: /dev/i2schar0
+
+config EXAMPLES_I2SCHAR_TX
+	bool "Use I2S transmitter"
+	default n
+	---help---
+		This should be set if the I2S device supports a transmitter.

+
+config EXAMPLES_I2SCHAR_TXBUFFERS
+	int "Number of TX buffers"
+	default 4
+	---help---
+		This is the default number of audio buffers to send before the TX
+		transfers terminate.  When both TX and RX transfers terminate, the
+		task exits (and, if an NSH builtin, the i2schar command returns).
+		This number can be changed from the NSH command line.
+
+config EXAMPLES_I2SCHAR_TXSTACKSIZE
+	int "Transmitter thread stack size"
+	default 1536
+	---help---
+		This is the stack size to use when starting the transmitter thread.

+
+config EXAMPLES_I2SCHAR_RX
+	bool "Use I2S receiver"
+	default n
+	---help---
+		This should be set if the I2S device supports a receiver.

+if EXAMPLES_I2SCHAR_RX
+
+config EXAMPLES_I2SCHAR_RXBUFFERS
+	int "Number of RX buffers"
+	default 4
+	---help---
+		This is the default number of audio buffers to receive before the RX
+		transfers terminate.  When both TX and RX transfers terminate, the
+		task exits (and, if an NSH builtin, the i2schar command returns).
+		This number can be changed from the NSH command line.

+config EXAMPLES_I2SCHAR_RXSTACKSIZE
+	int "Receiver thread stack size"
+	default 1536
+	---help---
+		This is the stack size to use when starting the receiver thread.

+endif # EXAMPLES_I2SCHAR_RX
+
+config EXAMPLES_I2SCHAR_BUFSIZE
+	int "Audio payload size"
+	default 256
+	---help---
+		The size of the data payload in one audio buffer in bytes.  Applies
+		to both TX and RX audio buffers.
+
+config EXAMPLES_I2SCHAR_DEVINIT
+	bool "Architecture-specific device initialization"
+	default 256
+	depends on !NUTTX_KERNEL
+	---help---
+		Define if architecture-specific I2S device initialize is available.
+		If defined, the the platform specific code must provide a function
+		i2schar_devinit() that will be called each time that this test
+		executes.  Not available in the kernel build mode.
