Thanks for info - Nonetheless, I
still have no output on my Lisa/L_v1.1 !2C port driving mkk
actuators - this has been the case since around 20 February .
I am using the most up to date
repository and a slightly modified Booz2_A7 airframe file -
changes include B2_v1.2 imu, mkk actuators and lisa/l_v1.1
My actuators worked perfectly on
an old Lisa /l_v1.0 board.prior to the date mentioned - I have
since had a new board supplied by Joby to enable the IMU mags

Hello all (especially developers),
Here are some modifications to the i2c driver for lpc21 :
- I removed the flag stop_after_transmit that was created for
a bad reason, that wasn't used anymore and was a source of
errors (the flag was not set correctly in the asctec driver
and it was sending crap). The default and only behavior is now
to send a stop after the transmit.
- When the slave is not responding (master get NACK on receive
or transmit request), the transaction is set to fail
(I2CTransFailed). If you check the state of your transaction
for success (I2CTransSuccess), don't forget to also check for
failure and take the appropriate action (skip or retry). FYI,
the previous behavior was to retry the transaction until the
slave respond, thus monopolizing the i2c line. This "feature"
actually made the asctec driver works by some black magic...
