this allows the last two flash sectors to be used as storage for
parameters, waypoints etc.
A change to the bootloader to not erase the last two sectors is needed
Pixracer has FRAM on the same bus as the ms5611 and the FRAM ramtron
driver does not use the same locking mechanism as other px4 SPI
drivers. We need to disable interrupts during FRAM transfers to ensure
we don't get FRAM corruption
This commit changes the way libraries headers are included in source files:
- If the header is in the same directory the source belongs to, so the
notation '#include ""' is used with the path relative to the directory
containing the source.
- If the header is outside the directory containing the source, then we use
the notation '#include <>' with the path relative to libraries folder.
Some of the advantages of such approach:
- Only one search path for libraries headers.
- OSs like Windows may have a better lookup time.
this does all IO in the timer thread, avoids writes that don't change
data, and does all writes in multiples of 128 byte chunks. This should
be about as friendly to SD cards as we can get.
