STDIO mapping

STDIO is routed to terminal via UART0 peripheral

CMSIS-Driver mapping

CMSIS-Driver	Peripheral	Connection
Driver_USART0	UART0	STDIN, STDOUT, STDERR
CMSIS-Driver VIO	VIO	CMSIS_VIO
Driver_vStreamAudioIn	VSI0	CMSIS_VSTREAM_AUDIO_IN
Driver_vStreamAudioOut	VSI1	CMSIS_VSTREAM_AUDIO_OUT
Driver_vStreamVideoIn	VSI4	CMSIS_VSTREAM_VIDEO_IN
Driver_vStreamVideoOut	VSI6	CMSIS_VSTREAM_VIDEO_OUT

CMSIS-Driver Virtual I/O mapping

VIO driver interfaces with the arm_vio.py Python stub implementation which stores and loads signal values.

CMSIS-Driver vStream configuration

Driver	Stream Format Description
Driver_vStreamAudioIn	16-bit PCM audio, 16000 samples/second
Driver_vStreamAudioOut	16-bit PCM audio, 16000 samples/second
Driver_vStreamVideoIn	RGB888 video, resolution 1280 x 720 (W x H)
Driver_vStreamVideoOut	RGB888 video, resolution 480 x 800 (W x H)
