This adds a counter here to only loop to a maximum number of iterations.
Now we avoid situations in which we would be stuck processing packets here.
This also adds some other meaningful defines
Removes compile-time selection of RCInput driver for ocpoc_zynq.
PPM and SBUS input are now colocated on the ocpoc board, and it
only needs to run RCInput_ZYNQ. Pulse input is also inverted
to accommodate SBUS input, which has no effect on PPM input.
On kernels 4.7+ duty_cycle should always be less than period.
Otherways, we'll get a EINVAL.
It makes sense to set duty_cycle to 0, as
duty_cycle doesn't really make sense without a proper period.
A proper way to handle these errors might be to call pwm_adjust_config
in every pwmchip backend but it's unrealistic to hope that all vendors
will do it quickly.
If we are the controlling terminal for a tty device we will receive a
SIGHUP when the device disappears. Currently what happens is that we
simply stop the whole process. We don't want to fall off the sky due
to a bad device. This can happen for any reason, but it's more likely
if the UART is behind a USB connection.
These messages are only valid in a small subset of Linux boards (those
based on BBB and variants). The ToneAlarm class should actually be
split allowing different implementations, but for now let's just disable
the message.
It's not being sold, there are just a few (different) engineering
samples built and there are no plans for this to go forward for people
that were pushing it.
There's an implicit (apart from the name) dependency between SPI and
SPIUARTDriver which results in a crush on a restart or a shutdown.
By moving the initialization we're making sure that all objects are
deleted in the right order.
_export_path and _duty_path will have been already long time gone by the
time dtors kick in.
Probably better to use OwnPtr around those. But it's better to be done
in a separate PR.
Checking the time on the tcpdump capture, it matches the first fields
from the data:
$ tshark -n -c 4 -r ~/tmp/solo/rc.pcap
1 0.000000 10.1.1.1 → 10.1.1.10 UDP 68 5005 → 5005 Len=26
2 0.019976 10.1.1.1 → 10.1.1.10 UDP 68 5005 → 5005 Len=26
3 0.040046 10.1.1.1 → 10.1.1.10 UDP 68 5005 → 5005 Len=26
4 0.059961 10.1.1.1 → 10.1.1.10 UDP 68 5005 → 5005 Len=26
From the previous commit (first 2 packets):
5fa8 f441 3414 0500 73d7 dc05 dc05 dc05 db05 e803 e803 e803 f401
73f6 f441 3414 0500 74d7 dc05 dc05 dc05 db05 e803 e803 e803 f401
0x0005143441f45fa8 - 0x0005143441f4f673 = 0x4E14 = 19988 (usec)
Which seems to approximately match for the other packets as well. We are
not using the field since we rather get the time when we receive it, but
at least use a better name.
