Hi,

a proposed minor "compatibility fix" is in the v4.2_aspirin2.2_compat branch on github.

Please test it.... but keep in mind that proper support for aspirin_v2.2 is only available in master and will be part of the next stable release.

Regarding baro on aspirin in master:
Michal... just noticed that you removed the support for the onboard bmp085 baro in your pull request.
I resurrected that and this is the default again.

There are three baro drivers to choose:
- BARO_BOARD_BMP085 (default)
- BARO_MS5611_SPI
- BARO_MS5611_I2C
To use the MS5611 on the Aspirin IMU, configure it in your firmware section, e.g.:

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

Cheers, Felix

Hi Christophe,

the poposed fix pulls PC13 high in arch specific part for the aspirin v1.x driver.

The aspirin2 driver you wrote is currently totally arch independent and does not initialize they GPIOs anywhere...

Cheers, Felix

Dear Michael,

Thank you for your debugging efforts and finding the important issue: the current release (v4.2) is not compatible with the new aspirin v2.2 (yet). Indeed if the SPI-Baro-Chip-Select is left floating, the the baro and the mpu6000 will fight each other every time the baro-chip-select is getting low (e.g. with your finger), so software MUST pull PC13 high.

While full support for the aspirin2.2 will only be given in the next paparazzi release (current master), v4.2 should be at least fixed.

Constraints:

-Lisa-m/2 with aspirin <= 2.1 -> PC13 soldered to ground

-Lisa-m/2 with aspirin >= 2.2 -> PC13 should be high

Proposed solution: https://github.com/paparazzi/paparazzi/pull/368

Can anyone verify/validate this?

Hi,

Btw, editing the makefile is annoying, just changed this in master so you can configure it from the airframe file, e.g.
<configure name="LISA_M_BARO" value="BARO_SPI"/>

default is BARO_I2C and another option would be BARO_ASPIRIN

Cheers, Felix

Hi,

If I understand you correctly you pulled up the CS pin permanently making communication to the barometer permanently impossible.

Am I right in the assumption you were not using master branch of paparazzi for your tests? To my knowledge only master branch has support for the MS5611 connected to SPI.

If you use master you need to edit conf/firmware/rotorcraft.makefile replacing:
BARO = BARO_ASPIRIN
with
BARO = BARO_SPI

then the barometer should be read out correctly as well as all other IMU sensors with no hardware modifications necessary.

I hope this helps.

Cheers Esden
