We pass "sizeof(i2c_integral_frame)" to hal.i2c->readRegisters(). Since
we have a padding in i2c_integral_frame we actually read 3 bytes more
than we should. Add PACKED to the struct so this is fixed.
i2c_frame doesn't have a padding (or hole) so there isn't this problem,
but since it's also used to calculate the frame size, use PACKED there
too.
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.
remove PANICs from init
return semaphore if init fails
add successful initialisation check before attempting to read from sensor
structure made private where possible
formatting fixes
check I2C reads succeed
add request_measurement to request sensor to produce measurement
quit after 20 of previous 40 reads fail
throttle reads to 10hz max
