This allows to consistently define:
Motor stopped - disarmed PWM
Motor idling - minimum PWM
Motor at full thrust - maximum PWM
Any allocation can then distinctly decide if
a motor should be running or not depending
on the context and also explicitly command that.
const char *data = "www\r\n";
Defines a cstring of 6 bytes: 'w', 'w', 'w', '\r', '\n', '\0'
type of data: char const*
type of &data: char const**
So when we call
write(_fd, &data, strlen(data));
then strlen(data) == 5
and we send the 4 byte memory address of data
+ some additional random byte.
Correct is
write(_fd, data, strlen(data));
where char const* gets casted to const void * and we pass
the pointer to the content of data.
The fundamental problem here is write() not being typesafe.
This adds support for the TI LP5562 RGB LED driver.
Things to note:
- The driver is initialized in simple PWM mode using its internal clock,
for R,G,B, but not for W(hite).
- The chip doesn't have a WHO_AM_I or DEVICE_ID register to check.
Instead we read the W_CURRENT register that we're generally not using
and therefore doesn't get changed.
- The current is left at the default 17.5 mA but could be changed using
the command line argument.

- ArmingStatus DroneCAN message STATUS field is only set to true based on
arming_status.armed
- Cannode prearm state is set to true always when ArmingStatus DroneCan
message is received
When we fall back to another link, we are already doing a uORB copy when
checking the data. Therefore, we should further down use/send that data
instead of overwriting it immediately.

I don't think it makes sense to slow down switching RTCM injection to
once every 5 seconds. If we don't have corrections, we should check and
use whatever we get as soon as possible.

We need to reset the instance after looping through all instances.
Otherwise, we are left with the last instance if none is valid but have
not updated the _selected_rtcm_instance which is what is logged.
Therefore, this change fixes the logged RTCM instance.

Maximum plaintext length was wrong, it is just k - 2 * hLen -2, where k is RSA key modulus length and hLen is hash length
Also minimum block that can be encrypted didn't make sense for RSA-OAEP, it is just 1 byte, the rest will be padded.
