RTC (Real Time Clock)

The device node is located at /dev/rtc. UC-7110 supports µClinux standard simple RTC control. You must include <linux/rtc.h> to use these functions.

1. Function: RTC_RD_TIME

int ioctl(fd, RTC_RD_TIME, struct rtc_time *time); Description: Reads time information from RTC.

2. Function: RTC_SET_TIME

int ioctl(fd, RTC_SET_TIME, struct rtc_time *time); Description: Sets RTC time.

Buzzer

The device node is located at /dev/console. UC-7110 supports µClinux standard buzzer control. UC-7110’s buzzer runs at a fixed frequency of 100 Hz. You must include <sys/kd.h> to use these functions.

1. Function: KDMKTONE

ioctl(fd, KDMKTONE, unsigned int arg);

Description: Buzzer will beep, as stipulated by the function arguments.

UART Interface

The normal tty device node is located at /dev/ttyM0…ttyM1, and modem tty device node is located at /dev/cum0 … cum1. UC-7110 Series supports µClinux standard termios control. Moxa UART Device API supports the configuration of ttyM0 to ttyM1 as RS-232/422/485. To use these functions, after the Tool Chain package is installed, copy the file “CDROM/libuc7110/uc7110.h” to the directory “/usr/local/arm-elf/include/” on your PC Linux, and then include <uc7110.h> in your codes.
