We are not doing any dma here, it's just an SPI transaction. Name them
only rx/tx (although io_packet_tx/io_packet_rx could be another option).
This also zero-initialize the struct to keep valgrind happy about not
calling ioctl() with uninitialized variables.
This disables FRAM usage in PXF and erleboard. The reason is it's
failing and not being used. Right now we get this on startup:
root@beaglebone:~# ./ArduCopter.elf
FRAM: Online
Storage: FRAM is getting reset to default values
Failed to read FRAM
Testing with valgrind also reveals some invalid memory reads. Let's
disable it for now to be common with other boards.
This commit adds support for OpticalFlow to MinnowBoardMax trying to
leave the OpticalFlow implementation as generic as it already is.
We had to add some format conversion and software crop to the cameras that
do not have this features.
Most cameras do not support NV12 or GREY formats, we are adding in this commit
a conversion from YUYV format, that seems pretty common in cameras, to GREY
format (since we do not use Cb and Cr data on OpticalFlow).
Also we are adding a software crop for 8bpp images, such as GREY format. For
the same reason, most cameras do not have support for overlaying (crop, resize
and so on).
These functions are being added in order to be used in the next commits,
where we will add support for OpticalFlow on MinnowBoardMax.
This reverts commit 8cca0beba9.
The PWM input using the RPI DMA is causing trouble with RPI boards using
PPMSUM. Let's revert it until the solution is found. We still leave the
ifdef in RCInput for BH hat.
The initial idea was to export all pins to be used at once, so we
created _export_pins() to take all of them and a wrapper method,
_export_pin() to export a single one. However we never export more than
one pin at once.
- Replaced PATH_MAX by the maximum stack memory it will use for GPIO
paths
- Added more information to error logs
- Removed the '/n' when writing to GPIO sysfs files
- Using Linux Util write_file() on _pinMode()
Make sure pinMode() method exports the pin before using it. Otherwise
the export method would need to be called, differently from other GPIO
implementations.
Since now export_pin and export_pins are called only internally, reduce
their visibility to protected.

Add proper casts to fix the compilation.
Let it be a static const member instead of defining it in a header. The
problem with the header is that it will generate conflicting symbols
when more than 1 compilation unit includes it.
