Define the default I2C buss frequncies that are backward compatible
with the existing code. While allowing it the defaults to be overridden
by a board config.
Based on the legacy STM32 code, the I2C buss numbering starts at 1.
The bus frequency is stored in a 0 based array. If px4_i2cbus_initialize
returns a valid device, then the _bus-1 will act as the index to the
busses frequency.
A board may define BOARD_NUMBER_I2C_BUSES - the number of I2C busses
it supports* and BOARD_I2C_BUS_CLOCK_INIT to initalize the bus
clocks for a given busses.
BOARD_NUMBER_I2C_BUSES - the number of busses including the *highest
number bus. If the board has 2 I2C
busses I2C1 and I2C3 BOARD_NUMBER_I2C_BUSES
would be set to 3
BOARD_I2C_BUS_CLOCK_INIT - Initalization for the bus frequencies
by bus. A call init, with a frequency
less then the value used for the
Initalization will result in the device
not starting becuase the buss runs too
fast for it.
This PR is preliminary ground work for FMUv5.
PX4 does not use the NuttX adc driver. But used the same format
for the data returned by the nuttx ADC driver.
There was a fixme:in src/platforms/px4_adc.h "this needs to be
a px4_adc_msg_s type" With this PR the need for
src/platforms/px4_adc.h goes away as the driver drv_adc.h now
describes the px4_adc_msg_t.
Remove the notion of legacy from the api. The board level code
will perform the traslation to lecacy format on the STM32.
new targets will not need to do this as there is no case
where the serial number were used by mfg for tracking.
Extend board common api to get mfguid and mfguid formatted
This adds an api that return the MFGUID as an array of bytes
or a string.
The data is returned with the MSD at index 0 and the LSD at
index PX4_CPU_MFGUID_BYTE_LENGTH-1.
Removed all reodering defines from the api and hal
This adds a src/board/<bebop|eagle|excelsior|rpi|sitl>/board_config.h
to configure the build as is done with the Nuttx targets
src/platforms/posix/include/board_config.h has been renamed to
src/platforms/posix/include/system_config.h to allow the common
posix defines to be included with the board specific defines.
