#Shortcuts in

lxterminal 0.2.0-1 (vivid) has a property tab for shortcuts.

In previous versions, there is no such possibility. I also tried to use the configuration of the newer version with the older version. It does not work.

Start the terminal:

  1. Click Edit > Preferences
  2. Select the Shortcuts tab
  3. Make your changes

Wifi - bring wlan0 up on boot

https://raspberrypi.stackexchange.com/questions/3200/wifi-bring-wlan0-up-on-boot?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa

I changed auto to allow-hotplug for wlan0 in my /etc/network/interfaces, see below:

sudo hciconfig wlan0 down

pi@raspbmc:~$ cat /etc/network/interfaces

#auto wlan0

allow-hotplug wlan0

iface wlan0 inet dhcp wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

Persistent tty devices name

To find data about your devices

lsusb

You should see something like:

dlinano@jetson-nano:/dev$ lsusb Bus 002 Device 002: ID 0bda:0411 Realtek Semiconductor Corp. Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 8087:0a2b Intel Corp. Bus 001 Device 009: ID 413c:2110 Dell Computer Corp. Bus 001 Device 007: ID 413c:1010 Dell Computer Corp. Bus 001 Device 006: ID 0461:4d15 Primax Electronics, Ltd Dell Optical Mouse Bus 001 Device 008: ID 2563:0526
Bus 001 Device 004: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light Bus 001 Device 002: ID 0bda:5411 Realtek Semiconductor Corp. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

THEN YOU CAN TRY something like that on different usb ports:

udevadm info -a -p $(udevadm info -q path -n /dev/ttyUSB1) | grep idProduct

And just replace /dev/ttyUSB0 by anything you think is your device tty

If the is a device at this tty, you will see somthing like:

udevadm info -a -p $(udevadm info -q path -n /dev/ttyUSB0) | grep idProduct ATTRS{idProduct}=="ea60" ATTRS{idProduct}=="5411" ATTRS{idProduct}=="0002"

else you will see something like:

dlinano@jetson-nano:/dev$ udevadm info -a -p $(udevadm info -q path -n /dev/ttyUSB0) | grep idProduct device node not found info: option requires an argument -- 'p'

to make sure you get the correct serial port, just read from it (that is if the device is continuously sending and is not waiting for data like while(!Serial.available())) For example to read from ttyUSB0:

cat /dev/ttyS0

If really you want to be fancy, you could use screen (you may have to install it)

sudo apt-get install screen

or even better, minicom (terminal interface)

sudo apt-get install minicom

You NEED to be sudo for setting the config file

To run: dlinano@jetson-nano:/dev$ sudo minicom -s

To exit: then Ctrl + A , Q

And try:

cd ~/RTKLIB/app/str2str/gcc

sudo ./str2str -in serial://ttyUSB0#ubx -out tcpsvr://:9000#rtcm3

There is no possibility to have a file INI to it but you can check the list of parameters by using:

./str2str -h

Use the option -msg to specify the output RTCM messages.

But wait, there is a possibility to use ini or conf files for rtksrv with the -o option. Also there a a ton of already made conf files.

for better exmples of conf files, just follow:

  1. https://github.com/rtklibexplorer/RTKLIB

  2. https://community.emlid.com/t/neo-m8t-with-rtkrcv-on-raspberry-pi-3/5521

For linux, only thoses CUI are available

./rtkrcv        RTKRCV        (CUI) *
./rnx2rtkp      RNX2RTKP      (CUI) *
./pos2kml       POS2KML       (CUI) *
./convbin       CONVBIN       (CUI) *
./str2str       STR2STR       (CUI) *

For example to find the idProduct of ttyUSB1

udevadm info -a -p $(udevadm info -q path -n /dev/ttyUSB1) | grep idProduct

Now edit the rule file AS SUDO

cd /etc/udev/rules.d

sudo nano ydnu.rules

ATTRS{idVendor}=="0483" ATTRS{idProduct}=="a217" ENV{ID_MM_DEVICE_IGNORE}="1"

ATTRS{idVendor}=="10c4" ATTRS{idProduct}=="ea60" ENV{ID_MM_DEVICE_IGNORE}="1"

ATTRS{idVendor}=="0403" ATTRS{idProduct}=="6001" ENV{ID_MM_DEVICE_IGNORE}="1"

Now edit the 99-com file AS SUDO

sudo nano 99-com.rules

(I saved this file (and the others as well) here just in case: My Dropbox

--> @ the beginning of the file: NO PASTE, EDIT

SUBSYSTEM=="input", GROUP="input", MODE="0660"

BE sure to have an internet connection BEFORE this step.

If there is no output in the terminal then that means it didn't work.

Before startting the file, you need to modify the addresses for (MAG+ACC) and (GYR)

  1. open LSM9DS0.py
  2. at the very top, edit:
