This page describe how to use Lisa/L from a user point of view
#REDIRECT [[Lisa/L]]
 
=Getting started=
 
* Install Gnu/Linux Ubuntu lucid lynx ( 10.04) and the paparazzi-dev, paparazzi-stm32 packages and paparazzi-omap( Installation from the Command Line: on this page [[Installation]] ).
sudo apt-get update
sudo apt-get install paparazzi-dev  paparazzi-stm32 paparazzi-omap
* Connect power to the board. The board accepts input voltage from 6V to 18V. The power connector is from JST and known in the rc world as a BEC connector
* Connect a mini USB cable in the mini USB connector. This should give you two USB devices. The first one ( usualy /dev/ttyUSB0) is the console for the Overo, the second one is the JTAG for the STM32
* Flash a test program in the stm32 :
  make AIRCRAFT=BOOZ2_A7 test_baro.upload
 
=== Overo ===
* The main documentation page for the overo on gumstix website is [http://www.gumstix.net/Setup-and-Programming/cat/Overo-Setup-and-Programming/111.html here].
* We now have a Overo toolchain package ! install the paparazzi-omap package.
sudo apt-get install paparazzi-omap
If you feel it's too easy, you can look at [http://paparazzi.enac.fr/wiki/LisaOveroImage here] and enjoy the fun of compiling openembedded yourself
* In order to use the SPI link between the STM32 and the Overo, you'll need a patched linux kernel and a couple of libraries. Look in the developer section if you wanna know the gore details of it. If not, just download our pre-compiled filesystem image and kernel from [http://paparazzi.enac.fr/overo/ here] and follow the instruction from [http://www.gumstix.net/Setup-and-Programming/view/Overo-Setup-and-Programming/Creating-a-bootable-microSD-card/111.html here] to write them on a micro sd card.
 
When you want the wright files to be downloaded en written on the SD do:
cd ~/sw/tools/overo_sd_maker/
sw/tools/overo_sd_maker
sudo ./overo_sd_maker.sh
 
 
*Once you have written your image to the sd card, you may insert it in the Overo and power Lisa. Connecting a mini usb cable to it will give you access to the console of the Overo as the first USB device ( usualy /dev/ttyUSB0). You can run a terminal like gtkterm or kermit to watch your Overo booting and log on it using root for login and no password.
 
For Kermit do:
sudo apt-get install ckermit
$ kermit -l /dev/ttyUSB0
C-Kermit>set flow-control none
C-Kermit>set carrier-watch off
C-Kermit>set speed 115200
/dev/ttyUSB0, 115200 bps
C-Kermit>connect
Connecting to /dev/ttyUSB0, speed 115200
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.
 
When you wait a few minutes your overo is booted from the SD card and you can log in if you see overo login:
 
overo login: root
root@overo:~#
 
* One on the first things you might want to do is setup wireless networking. Overo Air has a builting wifi adapter. On others you can use an external USB wifi stick. 
* Flash the STM32 with the link test program
  make AIRCRAFT=BOOZ2_A8 stm_test_spi_link.upload
* Compile and upload the Overo test program.
  make AIRCRAFT=BOOZ2_A8 overo_test_spi_link.upload
* Log on your Overo and run it
 
=Use case #1: the fixedwing firmware running in the STM32 only=
 
Coming soon... look for airframes/AirborneCodeReorg/LisaFw.xml
 
=Use case #2: the rotorcraft firmware running in the STM32 only=
 
Use the airframes/Poine/booz2_a7 as an example. You may only have to change some subsystems type to match your peripherals.
 
    make AIRCRAFT=BOOZ2_A7 ap.upload
 
=Use case #3: the lisa_passthrough firmware=
 
This firmware is about turning the STM32 into a simple io processor that sends sensors and radio control to the Overo and fetches actuators position in return.
 
The stm_passthrough target is what is ran on the STM32.
 
The overo_test_passthrough target demonstrates the use of the Paparazzi framework on the Overo: communications with the stm32, accurate periodic events and telemetry/datalink over wifi.
