Don't leave RX in bind mode in the unlikely eventuality that console
open fails

Jean Cyr 897b541b12 General cleanup of /dev/px4io and /dev/px4fmu 
- Use distinct common symbols for px4io and px4fmu device files, and use
instead of hardcoded filenames
- Use common symbols defining px4io bits consistently between px4fmu and
px4io builds.

Jean Cyr 20103f572f Minor px4io optimization 
Since this module creates the PX4IO object and that the IOCTL function
doesn't use the file descriptor parameter, there is no need to invoke
IOCTL via the filesystem since we can call it directly.

Jean Cyr 3f9f2018e2 Support binding DSM2 and DSMX satellite receivers 
The px4io bind command allows you to put a DSM satellite receiver into
bind mode. Since this feature requires that
the dsm VCC line (red wire) be cut and routed through relay one, it is
not enabled by default in order not to
affect those not using a DSM satellite receiver or wising to use relay
one for other purposes.

NOTE: Binding DSM2 satellites in 11-bit mode is not supported due to
potential bug in some DSM2 receiver streams
when in 11-bit mode. Furthermore the px4io software folds 11 bit data
down to 10 bits so there is no resolution
advantage to to 11-bit mode.

To enable the feature the RC_RL1_DSM_VCC parameter must be set to a non
zero value from the console, or using
QGroundControl:

param set RC_RL1_DSM_VCC 1

From the console you can initiate DSM bind mode with:

uorb start
param set RC_RL1_DSM_VCC 1
px4io start
px4io bind dsm2

For binding a DSMX satellite to a DSMX transmitter you would instead
use:

px4io bind dsmx

Your receiver module should start a rapid flash and you can follow the
normal binding sequence of your
transmitter.

Note: The value of parameter RC_RL1_DSM_VCC defaults to 0, so none of
this will have any effect on an unmodified
DSM receiver connection. For this feature to work, the power wire (red)
must be cut and each side connected to a
terminal on relay1 of the px4io board.

This has been tested using Spektrum as well as Hobby King 'Orange' DSM
satellite receivers.

Both px4fmu and px4io images are updated.

px4dev 6c5a15da9b Eliminate the TD DMA callback; we don't need to know that it's completed. 
Fix abort behaviour on timeouts, now we don't wedge after the first one.

px4dev d83323d4a2 Use the NuttX built-in crc32, it works fine. 2013-07-05 16:18:55 -07:00
px4dev 52096f017f Switch to the 'normal' way of doing register accessors. 
Be more aggressive en/disabling DMA in the UART, since ST say you should.
 2013-07-04 23:17:16 -07:00
px4dev 2e001aad04 Add PX4IOv2 support to the uploader. 2013-07-04 12:50:59 -07:00
px4dev f2079ae7ff Add DMA error handling. 
Add serial error handling.
Add short-packet-reception handling (this may allow us to send/receive shorter packets… needs testing).
 2013-07-04 11:21:25 -07:00
px4dev 7255c02c20 Add a test hook for the PX4IO interface. Wire up some simple tests for the serial interface. 
Signal quality looks good at 1.5Mbps. Transmit timing is ~450µs per packet, ~20µs packet-to-packet delay spinning in a loop transmitting.
 2013-07-03 23:41:40 -07:00
px4dev be6ad7af3b Rework the FMU<->IO connection to use a simple fixed-size DMA packet; this should let us reduce overall latency and bump the bitrate up. 
Will still require some tuning.
 2013-07-03 00:08:12 -07:00
px4dev d1562f926f More implementation for the serial side on IO; fix a couple of bugs on the FMU side. 
Still needs serial init and some more testing/config on the FMU side, but closer to being ready to test.
