Dear Marc,
thanks for your feedback:
2. The Airspeed sensor works on the I2C2 port with 3.3V (also written
in the specs). But initialisation seems to be a problem. Only after
(Luftboot)programming, the sensor delivers data. If I just plug the
battery in, airspeed is constant 8.. Sensor display shows numbers like
usual. Should there be some kind of pause in the ETS init? Or is this
an I2C related problem?
This problem is also known and a hacked solution is also in
the
tudelft/tudelft4.0/sw/airborne/arch/stm32/mcu_periph/i2c_arch.c
I tried the same thing. But no luck for me. (In fact the file was
already the same in my git checkout)
I also observe a static airspeed value in the messages (15m/s).
But I don't even see it working with going through luftboot first.
I forgot to mention. The Eagletree module flashes 3-4-2
