Lisa/L is a dual processor board autopilot designed to allow the possibility of using Linux for Paparazzi airborne code or advanced payload and path plannning. AN [[OMAP]]-based Gumstix [[Overo]] computer can be mounted directly to Lisa/L, with access to USB, SPI, and serial. The onboard STM32 microcontroller communicates with the Overo using a fast SPI interface. It can be used for both fixedwing and rotorcraft airframes. For links to additional documentation, please see [[Lisa|Lisa Overview page here]].


Lisa ( the Lost Illusions Serendipitous Autopilot) is a new range of autopilots based on [http://www.st.com/mcu/inchtml-pages-stm32.html STM32] microcontrollers ( CortexM3@72Mhz ) designed to run Paparazzi.
== Hardware Revision History ==
There's no such thing as a perfect autopilot, only autopilots adapted to a particular purpose. This is the reason why Lisa comes in different flavors for different usages.

=Getting started=
=== R/C Receivers ===


* Install Gnu/Linux Ubuntu and the paparazzi-dev, paparazzi-arm-multilib packages and paparazzi-omap( Installation from the Command Line: on this page [[Installation]] ).
==== Spektrum/JR remote receiver connection diagram ====
sudo apt-get update
There is a Spektrum parser available, enabling the direct use of 1 or 2 Spektrum satellite receivers.
sudo apt-get install paparazzi-dev  paparazzi-arm-multilib 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 ===
[[Image:Lisa_L_V1_1_satellite_receiver_connection.png|500px]]
* 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 files to be downloaded en written on the SD do:
==== PPM Remote receiver ====


  cd ~/sw/tools/overo_sd_maker/
To use the PPM signal of a PPM remote receiver, the input pin for the signal is the Trig.pin 1 (on UART1 connector), it is hardcoded and can not be changed. Also make sure that a bridge(~0 Ohm) in the conductor path is soldered. See below picture for the right position.
sw/tools/overo_sd_maker
sudo ./overo_sd_maker.sh


[[Image:LisaL-V1 1-top-labeled-marked.png]]


* Once you have written your OS 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.


Install the Kermit application via:
== PCB ==
$ sudo apt-get install ckermit


Then start up Kemit terminal application do:
=== Gerber & Drill Files  ===


  $ kermit -l /dev/ttyUSB0
'''''Download Lisa/L gerber & drill files (zip)''''' ''NOT YET AVAILABLE BUT SEE [[Lisa/L#Downloads|Downloads]]''
C-Kermit>set flow-control none
Need some generated gerbers and drill files here.
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:
== Assembly ==


overo login: root
===Components Layout===
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. 
''NOT YET AVAILABLE BUT SEE [[Lisa/L#Downloads|Downloads]]''
* Flash the STM32 with the link test program
Need some top and bottom of board images and line drawings here.
  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 #2: the rotorcraft firmware running in the STM32 only=
== PCB and assembled boards suppliers ==


Use the airframes/Poine/booz2_a7 as an example. You may only have to change some subsystems type to match your peripherals.
Available on [[Get_Hardware|Get Hardware]] page, hopefully :)


    make AIRCRAFT=BOOZ2_A7 ap.upload


=Use case #3: the lisa_passthrough firmware=
== Mechanical Dimensions ==


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.
Lisa/L's four mounting holes fit M3 screws or standoffs. Their centers are in a square 43.8mm on a side.


The stm_passthrough target is what is ran on the STM32.
NEED LISA/L MECHANICAL DRAWING.


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.
