====== Development tools ======

===== ARM GNU C/C++ toolchain for bare-metal devices =====

Download the arm-none-eabi-gcc-4.9 toolchain from the GNU ARM Embedded Toolchain project (currently tested with the 14.07 release https://launchpad.net/gcc-arm-embedded/+milestone/4.9-2014-q4-major ).

Extract the archive (e.g. to ~/toolchains ).

Update your PATH to find the newly installed toolchain. In your ''~/.profile'' (for //bash//) or your ''~/.zshrc'' (for //zsh//) , add 
<code>
PATH="$HOME/toolchains/gcc-arm-none-eabi-4_9-2014q4/bin:$PATH"
</code>

Restart your session so that is sourced again, and verify that you are running the correct arm-none-eabi-gcc version:

<code>
$ arm-none-eabi-gcc --version
arm-none-eabi-gcc (GNU Tools for ARM Embedded Processors) 4.9.3 20141119 (release) [ARM/embedded-4_9-branch revision 218278]

===== Add compiler to Code::Blocks =====

If you want to use an IDE like Code::Blocks, you can configure it to use the newly installed toolchain.

  * Settings > Compiler
  * Copy "GNU GCC Compiler", call the new compiler "Quimesis ARM Linux Compiler"
  * Toolchain executables:
    * Compiler's installation directory: $HOME/toolchain/usr/bin
    * C compiler: //arm-linux-gcc//
    * C++ compiler: //arm-linux-g++//
    * Linker for dynamic libs: //arm-linux-g++//
    * Linker for static libs: //arm-linux-ar//

When you create your project in Code::Blocks, be sure to select the "Quimesis ARM Linux Compiler".

===== Libraries for host developments =====

===== Run a 32-bit toolchain on a 64-bit Ubuntu =====

<code>
sudo apt-get install lib32stdc++6
sudo apt-get install lib32z1
</code>

===== CANUSB module =====

To use the CANUSB module :
  - Connect CAN_L (pin2), CAN_H (pin7) and CAN_GND (pin3) (see http://www.can232.com/?page_id=16)
  - Follow this step-by-step guide to install the Lawicel CANUSB adapter on Linux (**mainly step 1 to 6**) : http://pascal-walter.blogspot.com/2015/08/installing-lawicel-canusb-on-linux.html

In brief :
  * Install **can-utils** package :
<code>
sudo apt-get install can-utils
</code>
  * Check if the kernel modules "can", "can_raw" and "slcan" are already loaded using **lsmod**. If not 
<code>
sudo modprobe can
sudo modprobe can_raw
sudo modprobe slcan
</code>
Make them load automatically :
<code>
sudo nano /etc/modules
</code>
Add the three modules "can", "can_raw" and "slcan" to the list (each goes in one line).
  * Bind the CANUSB device (on port **/dev/ttyUSB0**) to the slcan interface (**slcan0**) and set up baud rate to 1Mbit/s (**-s8**) :
<code>
sudo slcand -o -c -f -s8 /dev/ttyUSB0 slcan0
</code>
  * Bring the slcan interface up :
<code>
sudo ifconfig slcan0 up
</code>
  * To intercept CAN messages (sended and received) :
<code>
candump slcan0
</code>
  * To send a CAN message (for CAN 2.0 frames, max 8 bytes separated by '.' and given in hex format) :
<code>
cansend slcan0 <ID>#<byte1>.<byte2>.<...>.<byte8>
</code>


===== USB-I2C (USB-ISS) module =====

from [[https://www.robot-electronics.co.uk/htm/usb_iss_tech.htm]]

To be used with [[https://github.com/milidam/devantech | i2c-devantech-iss]] kernel module, to access a dedicated ''/dev/i2c-x'' device on one's Linux desktop.

Then you can use the ''/dev/i2c-x'' device directly, or request another kernel module to use it:
<code>
echo <your_module> <device_address> > /sys/bus/i2c/devices/i2c-<x>/new_device
</code>

When using ''zsh'', the latest command may result into failure ''zsh: file exists: /sys/bus/i2c/devices/i2c-<x>/new_device''; in that case, just switch to //bash//, and the same command will succeed.

===== FLIR cameras =====
==== PureThermal2 USB module ====

https://groupgets.com/manufacturers/getlab/products/purethermal-2-flir-lepton-smart-i-o-module
https://lepton.flir.com/getting-started/

On Ubuntu, can be used with the [[https://github.com/groupgets/GetThermal|GetThermal interface]].


==== FLIR ONE PRO ====

Normally foressen to work with Android.

But can be used on Linux using [[https://source.dpin.de/nica/flir-gtk|flir-gtk]]((on Ubuntu < 20.04, this requires the amnual install of https://github.com/DaveGamble/cJSON)).
