A board only needs to define:
#define RC_SERIAL_PORT "/dev/ttyS4"
Then it can optionally define one or more of the following:
#define RC_SERIAL_SWAP_RXTX
#define RC_SERIAL_SINGLEWIRE
#define RC_INVERT_INPUT(_invert_true) px4_arch_gpiowrite(GPIO_SBUS_INV, _invert_true)
I2C bus chaged I2C0 is external, I2C1 internal
Added BMM150 on I2C1 @ Addr 0x100
Added BMP280 on I2C1 @ Addr 0x76
UART0 (/dev/ttyS1) now used at Telem 2
Chip select added for W25X40CLUXIG Calibration EE prom
Driver is not added at this time
This updating of the driver setting is for EMI issue with GPS and FCC.
With this setting the clock is sinusoidal
N.B. sd_bench fails on SanDISK HC, but Passes SanDISK **HC1** and
Kingston cards.
****Use HC1 or Kingston cards!***
Testing done on SanDISK HC all failed sd_bench with Drive/Slew other
than default and _PIN_OUTPUT_FAST|_PIN_OUTPUT_HIGHDRIVE
_PIN_OUTPUT_FAST|_PIN_OUTPUT_HIGHDRIVE Square noisy, pass SanDISK HC
_PIN_OUTPUT_FAST|_PIN_OUTPUT_LOWDRIVE Square noisy, pass SanDISK HC
_PIN_OUTPUT_HIGHDRIVE|_PIN_OUTPUT_SLOW sinusoidal fail SanDISK HC, pass SanDISK HC1
_PIN_OUTPUT_LOWDRIVE |_PIN_OUTPUT_SLOW sinusoidal fail SanDISK HC, pass SanDISK HC1
_PIN_OUTPUT_SLOW sinusoidal fail SanDISK HC, pass SanDISK HC1
