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
This is a back port of upstream NuttX PX4 contrib of
ef42c25 stm32f7:SDMMC add dcache alignment check in dma{recv|send}setup
In the where CONFIG_SDIO_PREFLIGHT is not used and dcache
write-buffed mode is used (not write-through) buffer alignment
is required for DMA transfers because a) arch_invalidate_dcache
could lose buffered writes data and b) arch_flush_dcache could
corrupt adjacent memory if the buffer and the bufflen, are not on
ARMV7M_DCACHE_LINESIZE boundaries.
1e7ddfe stm32f7:SDMMC remove widebus limitation on DMA
There is no documantation for the STM32F7 that limits DMA on
1 bit vrs 4 bit mode.
dffab2f stm32f7:DMA add dcache alignment check in stm32_dmacapable
In the case dcache write-buffed mode is used (not write-through)
buffer alignment is required for DMA transfers because
a) arch_invalidate_dcache could lose buffered writes data and
b) arch_flush_dcache could corrupt adjacent memory if the
maddr and the mend+1, the next next address are not on
ARMV7M_DCACHE_LINESIZE boundaries.
38cbf1f stm32f7:DMA correct comments and document stm32_dmacapable
Updated comment to proper refernce manual for STM32F7 not STM32F4.
Added stm32_dmacapable input paramaters documentation.
* Unfortunately, due to the SWIG dependency, we need sudo to install on
Travis (conflicts when adding with debian-sid source prevent using addons)
which means we cannot use the container-based infrastructure anymore.
* Building the Python bindings requires g++5 (at least with -Werr set).
* When building the Python bindings on Travis, the numpy includes are not found
by cmake, so they have to be added separately by running a Python process with
`numpy.get_include()`
* The build script now (somewhat clumsily) depends on the RUN_PYTEST environment
variable. If it is set to anything other than "", it will make the tests and
run tests and benchmarks
