我也遇到了 owfs 的问题。我发现它是一个简单问题的过度设计的解决方案。现在我使用DigiTemp代码没有问题。我发现它灵活可靠。例如,我通过运行每分钟将房间的温度存储在一个日志文件中
/usr/local/bin/digitemp_DS9097U -c /usr/local/etc/digitemp.conf \
-q -t0 -n0 -d60 -l/var/log/temperature
为了达到这一点,我下载了源文件,解压它,然后执行以下操作。
# Compile the hardware-specific command
make ds9097u
# Initialize the configuration file
./digitemp_DS9097U -s/dev/ttyS0 -i
# Run command to obtain temperature, and verify your setup
./digitemp_DS9097U -a
# Copy the configuration file to an accessible place
cp .digitemprc /usr/local/etc/digitemp.conf
我还手动编辑了我的配置文件以将其调整为我的设置。这就是它的结局。
TTY /dev/ttyS0
READ_TIME 1000
LOG_TYPE 1
LOG_FORMAT "%b %d %H:%M:%S Sensor %s C: %.2C F: %.2F"
CNT_FORMAT "%b %d %H:%M:%S Sensor %s #%n %C"
HUM_FORMAT "%b %d %H:%M:%S Sensor %s C: %.2C F: %.2F H: %h%%"
SENSORS 1
ROM 0 0x10 0xD3 0x5B 0x07 0x00 0x00 0x00 0x05
在我的情况下,我还创建了一个 /etc/init.d/digitemp 文件并使其在启动时运行。
#! /bin/sh
