Re: [Paparazzi-devel] Eagle Tree airspeed sensor startup testers needed

[Stephen Dwyer]

Hello,

I tried this out, and it was only working after a luftboot upload, not
after a regular bootup sequence. It was on a Lisa/M v2.0, nothing else
connected but UART2, on the Bixler example airframe, with the sensor
connected to I2C2. When it was working, it wasn't overly reliable,
with a considerable number of NACKed bytes in the transactions. The
same results occurred with a delay of 2sec or 8sec.

Perhaps someone else could also test?

I also tried the ETS sensor in master, and that worked much better,
but there was still a 10-20% transaction failure rate (NACKed bytes).

Thanks,
-Stephen Dwyer

P.S. I used the following in the airframe file:
In Firmware section:

<define name="USE_I2C2"/>

In Modules:
<modules>
    <load name="sys_mon.xml"/>
    <load name="airspeed_ets.xml">
      <define name="AIRSPEED_ETS_START_DELAY" value="2"/>
      <define name="AIRSPEED_ETS_I2C_DEV" value="i2c2"/>
      <define name="SENSOR_SYNC_SEND"/>
    </load>
  </modules>
