Re: [Paparazzi-devel] gps for Lisa/m

[Felix Ruess]

Hi Jorn,

I have been running the stable branch, so this is probably the cause of why I have been having problems with the baro(?) (Compiling for Aspirin 2.1 works, but then the BMP085 baro can probably not work?)

The bmp085 baro (which is mounted on Lisa/M if yours still has one) works fine on v4.2.

Aspirin v2.2 is however not fully supported on v4.2 (the ms5611 baro on aspirin won't work).

To at least have partial support for aspirin 2.2 on v4.2 (so you can use the imu without baro) have a look at:

https://github.com/paparazzi/paparazzi/pull/369

We still need someone to test the compatibility patch...

 

When compiling for Aspirin 2.2, I have the following error message: 

Run 'make -C /home/jorn/paparazzi -f Makefile.ac AIRCRAFT=YAPA_Chimu ap.compile '
make: Entering directory `/home/jorn/paparazzi'

make: Leaving directory `/home/jorn/paparazzi'

DONE (exec make -C /home/jorn/paparazzi -f Makefile.ac AIRCRAFT=YAPA_Chimu ap.compile  2>&1)

There is no aspirin_v2.2 subsystem/makefile in v4.2, since it is not properly supported.

If the file conf/firmwares/subsystems/shared/imu_aspirin_v2.2.makefile exists on your v4.2 branch then it must be one you added (accidentally?)

Basically I prefer to use the stable branch, (since it is supposed to be stable), but I would like to change to master in order to test a close to finished setup for the Aspirin 2.2.

Yeah... you'll need to deal with the bleeding edge version if you want to use the ms5611 baro on aspirin. 

Cheers, Felix

Hi Jorn,

I am in the process of setting up a new Lisa/M board with the new Asprin 2.2. I have got the board up an running, connected wireless by a pair of 3DR 433 modules http://store.diydrones.com/3DR_RadioTelemetry_Kit_433Mhz_p/kt-telemetry-3dr433.htm but still do have a few issues to work out. Like obtaining a connection to the gps http://store.diydrones.com/3DR_GPS_LEA_6_p/br-3drlea-6.htm (which is running and do have a lock - according to the leds) - but not signing up in the gcs, calibrating the IMU (drifting), getting connected to the ppm-rx.

When compiling the code, it looks like the Aspirin 2.2 is currently not supported in the master branch, so I changed to Aspirin 2.1, which compiles without errors, but which probably does not support the new baro; "The drivers for the MS5611-01BA03 are work in progress and will be available in the master branch of the Paparazzi codebase soon. All help with testing and improving the driver are very welcome!"

It is supported in latest master, just choose "aspirin_v2.2" as imu type. *should* (tm) work fine, but I don't have a aspirin_v2.2. to test...

In this context, I wonder what is the current status of the master branch with regard to support for the Lisa/M?

Lisa/M hasn't changed, so this is fine...

The only thing that you might have to choose is which baro you want to use with Lisa/M 2 and aspirin_v2.2:

There are three baro drivers to choose:

    - BARO_BOARD_BMP085 (default)

    - BARO_MS5611_SPI

    - BARO_MS5611_I2C

To use the MS5611 connected via SPI on the Aspirin IMU, configure it in your firmware section, e.g.:

    <configure name="LISA_M_BARO" value="BARO_MS5611_SPI"/>

E.g. would it be best to let it rest for a while, until more issues are worked out?

Could you be a bit more specific? Which issues are you having and which paparazzi_version are you running?

Please update to the latest master first if you have problems...

 

And, are these parts of the wiki up to date:
- http://paparazzi.enac.fr/wiki/GPS
- http://paparazzi.enac.fr/wiki/Tunnel

For the most part, probably yes... if you find anything that is not, feel free to report/update it.

But note that there is currently no usb tunnel available for the stm32 autopilots (e.g. Lisa), only the uart tunnels..

Cheers, Felix
