USB host interface, I2C interface | Digi 9P 9360/9750 specification

USB host interface

A USB host driver is included and enabled in the default kernel configuration. To operate multiple USB devices simultaneously, connect a USB hub to the USB host port.

A memory stick can be mounted as followed

#lxmount usb

#ls -l /media/usbdisk

I2C interface

A driver for the I2C interface is included and enabled in the default kernel configuration. Devices attached to the I2C interface can be accessed via /sys/bus/i2c/device/<your device>.

SPI interface

A driver for the SPI interface is included and enabled in the default kernel configuration. It can be accessed via /sys/bus/spi/device/<your device>.

LCD interface

A LCD frame buffer driver is included and enabled in the default Linux kernel configuration.

Touch screen interface

CC9P9360/9750

A driver for the touch controller on the LCDMODARM development board, which is connected via SPI, is included and enabled in the default Linux kernel configuration.
