Re: [Paparazzi-devel] Eagletree airspeed sensor problems

[Felix Ruess]

Well, what is documented in the manual is for the third party mode (outputs mph or kph), which has to be configured using some eagle-tree windows tool first.

We are using the eagle-tree mode (raw), which is not really documented it seems.

Here is the pseudo code for accessing the Airspeed and Altimeter sensors:
byte data[2];
signed short reading = 0xFFFF;
i2c_start();
// select sensor in write mode
if (!(i2c_write(SENSOR_ADDRESS | I2C_WRITE_BIT))) {
// send "read data" command to sensor
if (!i2c_write(0x07)) {

  if (airspeed_ets_i2c_trans.status == I2CTransDone)
    I2CReceive(AIRSPEED_ETS_I2C_DEV, airspeed_ets_i2c_trans, AIRSPEED_ETS_ADDR, 2);

Is this correct?
