The TECS controller belongs really into the ECL (estimation & control library) where we have collected a number of vehicle control systems. It is being replaced by a new implementation of the algorithm, contributed by Paul Riseborough.
inverted S.bus signal and fetch the data of each channel and publish it
2. Fix the bug of linux_pwm_out, when the protocol is pca9685,
after the init method is executed,the method of determining the return
value of init method is incorrect,this will cause the driver to fail
3. Add linux_sbus driver to other posix prefixes cmake files
Add -D__DF_RPI in posix_rpi_common.cmake
Add rpi_rc_in and rpi_pca9685_pwm_out driver in posix_rpi_common.cmake
Rename posix_rpi_cross_without_navio_or_pxfmini to posix_rpi_cross_no_shield.cmake
The reason for this change is that RPi2 and RPi3 are compatible, and
hopefully all differences coming up can be resolved without ifdefs but
at runtime.
