Подключение адаптера RS-232
^  Raspberry Pi  ^  Адаптер  ^
|4: +5V  |VCC  |
|6: GND  |GND  |
|8: TXD  |RXD  |
|10: RXD  |TXD  |


У адаптера микросхема с ножками:
11 - RX
12 - TX

обычно порядок такой:
VCC
TXD
RXD
GND

===== rtc ds3231 =====

<WRAP tip>В общем-то, можно и не использовать часы, если настроить синхронизацию времени с windows-компом</WRAP>

{{:doc:jroboplc:ds3231_module.jpg?400|}}

  sudo apt-get install python-smbus i2c-tools
  sudo apt-get purge fake-hwclock ntp
  sudo apt-get install ntpdate

Add at the end:
  sudo mcedit /boot/config.txt
  dtoverlay=i2c-rtc,ds3231

Add the line (above “exit 0”):
  sudo mcedit /etc/rc.local
  /sbin/hwclock -s
  
Change:
  sudo mcedit /etc/init.d/hwclock.sh
  HWCLOCKACCESS=no
  
reboot

  sudo date -s "10 OCTOBER 2016 10:00:00"
  sudo hwclock -w  


===== java =====

Скачать JDK 8 (Linux ARM v6/v7 Hard Float ABI) [[http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html|здесь]] и скопировать в ''/data''. Номер версии (101) заменить на нужный.

  sudo su
  mkdir /usr/lib/jvm
  mv /data/jdk-8u101-linux-arm32-vfp-hflt.tar.gz /usr/lib/jvm
  cd /usr/lib/jvm
  tar xzvf jdk-8u101-linux-arm32-vfp-hflt.tar.gz
  rm jdk-8u101-linux-arm32-vfp-hflt.tar.gz
  ln -s jdk1.8.0_101 java-8-oracle


  sudo mkdir /data
  sudo chmod 777 /data
  sudo mkdir /usr/lib/jvm
  sudo chmod 777 /usr/lib/jvm
  
  # скопировать дистрибутив с другого компа при помощи mc/Shell Link... пример адреса:

  cd /usr/lib/jvm
  # перенести дистрибутив и распаковать
  tar -xzvf jdk-8u391-linux-aarch64.tar.gz
  sudo ln -s jdk1.8.0_391 java-8-oracle



===== temperature =====
<file bash temperature.sh>
#!/bin/bash
cpuTemp0=$(cat /sys/class/thermal/thermal_zone0/temp)
cpuTemp1=$(($cpuTemp0/1000))
cpuTemp2=$(($cpuTemp0/100))
