Простое чтение данных.

#!/usr/bin/perl
    use GPS::NMEA;
    use Data::Dumper;
    
    my $gps = GPS::NMEA->new(Port => '/dev/cuaa0', # or COM5: or /dev/ttyS0
                             Baud => 4800);
    while(1) {
        $gps->parse;
    
        # Dump internal NMEA data:
        $gps->nmea_data_dump;
    
        # Alternative to look at the internal NMEA data:
        require Data::Dumper;
        print Data::Dumper->new([$gps->{NMEADATA}],[])->Indent(1)->Useqq(1)->Dump;
    }

Печатаем координаты.


 #!/usr/bin/perl
    use GPS::NMEA;
    use Data::Dumper;
    
    my $gps = GPS::NMEA->new(Port => '/dev/cuaa0', # or COM5: or /dev/ttyS0
                             Baud => 4800);
    while(1) {
        $gps->parse;
    
        # Dump internal NMEA data:
        $gps->nmea_data_dump;
    
        # Alternative to look at the internal NMEA data:
        require Data::Dumper;
        print Data::Dumper->new([$gps->{NMEADATA}],[])->Indent(1)->Useqq(1)->Dump;
    }

Дамп всех NMEA данных с порта.

    my $gps = GPS::NMEA->new(Port => '/dev/cuaa0', # or COM5: or /dev/ttyS0

Fex Guide – Описание FEX стандарта

/boot/cb2-hdmi.bin
# bin2fex cb2-hdmi.bin > cb2-hdmi.txt
# fex2bin cb2-hdmi.txt cb2-hdmi.bin

PH20 – Зеленый светодиод на плате.

Все порта должны быть прописаны а также не должны пересекаться.

[gpio_para]
gpio_used = 1
gpio_num = 3
gpio_pin_1 = port:PH20<1><default><default><1>
gpio_pin_2 = port:PH21<1><default><default><1>
gpio_pin_3 = port:PD1<1><default><default><1>

#cd /sys/class/gpio
#ls -al
 export
 gpiochip1 -> ../../devices/platform/gpio-sunxi/gpio/gpiochip1
 unexport

Активация порта PH20. (echo 3 -> для PD1)
# echo 1 > /sys/class/gpio/export 
# ls -al
 export
 gpio1_ph20 -> ../../devices/platform/gpio-sunxi/gpio/gpio1_ph20
 gpiochip1 -> ../../devices/platform/gpio-sunxi/gpio/gpiochip1
 unexport

Включаем режим вывода.
# echo out > gpio1_ph20/direction 

Читаем из порта.
# cat gpio1_ph20/value
 0

Записываем в порт.
# echo 1 > gpio1_ph20/value
# cat gpio1_ph20/value
 1

Проверенно, работает.

Cubieboard / Cubietruck Debian Wheezy SD card image

Cubieboard / Cubietruck Debian Wheezy SD card image.

Debian Wheezy 7.5 based
Kernel 3.4.91 with broad hardware support, headers included
Ethernet adapter with DHCP and SSH server ready on default port (22) with regenerated keys @ first boot
Wireless adapter with DHCP ready but disabled (/etc/network/interfaces, WPA2: normal connect or AP mode)
Enabled audio devices: analog, spdif and I2S
Advanced IR driver with RAW RX and TX
Bluetooth ready (currently working only with supported external USB devices)
Clustering / stacking
USB redirector – for sharing USB over TCP/IP (disabled by default /etc/init.d/rc.usbsrvd)
root file-system auto resize
Graphics desktop environment upgrade ready
NAND and SATA install script included (/root)
Disabled LED blinking, logo, boot messages (/etc/init.d/disable_led.sh, kernel.config, kernel parameters in uEnv.txt)
Total memory is exactly 2000Mb (disabled all memory reservations for GPU)
Login script shows Cubietruck / Cubieboard 2 auto MOTD with current CPU temp, hard drive temp & actual free memory
MAC address from chip ID, manual optional
Fastest Debian mirror auto selection @ first boot
root password=1234
sunxi-tools included: fex2bin, bin2fex, nand-part
Performance tweaks:
- /tmp & /log = RAM, ramlog app saves logs to disk daily and on shut-down
- IO scheduler NOOP for SD, CFQ for sda (mechanical hard drive). (change in /etc/sysfs.conf)
- journal data writeback enabled. (/etc/fstab)
- commit=600 to flush data to the disk every 10 minutes (/etc/fstab)
- optimized CPU frequency scaling 480-1200Mhz with interactive governor and small 20% overclock (/etc/init.d/cpufrequtils)
Known bugs or limitations
- On board Bluetooth unstable / unusable (firmware issue)
- NAND install script sometime fails. Dirty but working workaround – installing Lubuntu to NAND with Phoenix tools and run the nand-install again.
- Gigabit ethernet transfer rate is around 50% of its theoretical max rate (hardware or firmware issue)
- Shutdown, reboot and battery troubles regarding poor AXP chip driver (firmware issue, probably solved in development kernel)

Unzipped images can be written with Image Writer on Windows or with DD command in Linux/Mac (dd bs=1M if=filename.raw of=sd card device). Kernel package should be uncompressed under root user to / Change boot parameter if your old kernel has different name.

VGA/HDMI переключение.

Данный метод не работает.

# To switch VGA/HDMI display mode in command line. e.g.
$ cb-display-tool -o 8 -m 11
# Note: can switch to the same resolutions only currently.

А вот если изменить script.fex

[disp_init]
disp_init_enable = 1
disp_mode = 0
screen0_output_type = 4
screen0_output_mode = 4
screen1_output_type = 2
screen1_output_mode = 14

То все работает.

Для конвертации из bin to fex : bin2fex script.bin > script.fex
для конвертации из fex to bin : fex2bin script.fex > script.bin

При выполнения некоторых команд появляется вот такая ошибка.

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "ru_RU.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory

Решение проблемы:

sudo apt-get install --reinstall language-pack-en
sudo locale-gen
sudo dpkg-reconfigure locales
sudo locale-gen ru_RU.utf8
