Karl Knutsson
137c183ec2 OP-1522 Remove unused channel set cfg 
Remove unused channel set configuration option.
With the new channel allocation the old channel set
configuration isn't needed.

a3715598c7 OP-1522 New channel allocation 
Generate a pseudo random list of channels from hmac_sha1 with the
coordid as key.

Enforce channel spacing based on the frequency deviation derived
from the configured data rate.

9bf18490b1 OP-1522: Channel timeout logic 
Use real time rather than missed pickets when deciding if we are
disconneted. Makes the link less sensitive at higher rates since
higher rates means more chances to get a packet through within the
given time.

b0491da115 OP-1576: Remove unused tx_resent counter

rx_failure in link quality calculations.

52c1080ffe OP-1522 Robustness of OPLink radio 
Increase number of channels to 32 for all bit rates.
Synchronize clock on all channels.
Go into failsafe after 4 or 8 (one_way_link) missed packets.
Don't stay on channel 0 if we dropped a packet.

966ef5ce75 OP-1680 Increase the range and resolution of OPLink PPM values 
Encode 511 steps plus a single "invalid" value, rather than 256 steps
plus a dedicated valid flag bit. This gives a range of 990 - 2010 us in
steps of 2 us.

d9a3fac502 Disable the "preamble invalid" interrupt for the RFM22b module. It causes 
high CPU load and isn't used anyway.

This reverts commit 9fd4fb26b9.
 2014-10-16 08:23:10 +02:00
Karl Knutsson
9fd4fb26b9 OP-1532 fix non-ppm mode 
Always send packets from the coordinator.
Previously the coordinator only always sent packets
on channel 0. This scheme doesn't work with
with the change to use 32 channel.

Karl Knutsson
4e365f6dff OP-1530 Use rfm22b_dev->num_channels 
Use the number of allocated channel from the num_channels field
in the pios_rfm22b_dev struct rather than from the maximum number
of possible of channels given the configured speed.

d0d8a0aadd OP-932 Adds PWM outputs to OPLinkMini. Both gpio pins on the main and/or flexi port can be configured to output PWM for a total of up to 4 PWM outputs. 2013-07-03 18:58:34 -07:00

c76ee7de9d OP-932 Fixes the failsafe that detects when the Rx modem loses sync with the Tx modem. This was not working on one-way mode. 2013-06-30 16:08:50 -07:00
Brian Webb
491e5fe685 Adds a failsafe on PPM output on OPLink that kicks in when the link goes down. Also updates all air datarate settings and adds new 64 and 100 kbps modes. 2013-06-29 15:00:38 -07:00

Brian Webb
2aea2342ab OP-932 Adds a direct PPM channel on each Tx packet when in PPM mode, and adds a PPM only mode that uses a 9600 bps air datarate. Also updates the OPLink configuration tab and moves all OPLink configuration to the OPLink configuration tab on the Revo, and customizes the OPLink configuration tab for the Revo. 2013-06-26 18:01:54 -07:00

Brian Webb
61c453f6ff Removes several of the air datarate settings, and fine tunes the calculation of the max packet length from the datarate and packet time. 9600, 19200, 36400, and 57600 modes tested. Tested 19200 in one-way mode for PPM only. 2013-06-26 17:59:33 -07:00

cdd51537f1 Fixes the 9600 bps air datarate for the RFM33B modem. 2013-06-26 17:57:46 -07:00
Brian Webb
fc0328a3cd OP-932 Adds working one-way mode to the OPLink radio connection. In this mode, packets will only flow from the ground side (coordinator modem) to the flight side modem. 2013-06-26 17:57:32 -07:00
Brian Webb
774a74884a OP-932 Replaces the RFM22B PPM/receiver code with an OPLinkReceiver UAVObject. This object is generated on a coordinator OPLink, and is used by both the OPLink to generate PPM output, and the OPLinkReceiver on the Revo. 2013-06-26 17:57:11 -07:00
Brian Webb
8c370df319 OP-932 A significant re-work of the OPLink and configuration of the OPLink. Auto-configuration is removed, and remote modems are bound the coordinator, rather than the other way around. Timing of the radio link is also significantly changed. The rfm22b code is also simplified so that it only sends packet, and has no notion about what those packets are, so the rfm22b is converteded to simply a com type device. 2013-06-26 17:56:56 -07:00
Brian Webb
e9f83bcc80 Fixes a bug in the rfm22b driver that was reading past the end of the bindings list when receiving a status message. Also adds some formatting changes that came about after doing a make uncrustify_all. 2013-05-26 08:36:38 -07:00

ac4847c8ac OP-932 Moves the configuration of the com ports on the coordinator OPLink to startup. 2013-05-21 19:48:21 -07:00
Brian Webb
dbce08a151 OP-932 Changes the radio task loop to loop every 1ms, and reduces the tx transmit period back down to 8ms. Also reduces the Tx windows to 1ms for each modem, and reserves the latter half of the Tx window for channel changing. 2013-05-21 17:40:05 -07:00
Brian Webb
d4a4588011 OP-932 Changes the RFM22 frequency hopping to change channels every Tx period. Also increases the Tx clock period from 8ms to 16ms, and adds a check on calculation the the time delta that it doesn't change the previous estimated time delta by too much. If the delta between the current time delta and the previously estimated time delta is too large it could indicate that there was a delay somewhere that makes the calculated time delta inaccurate. 
Rearanges the packet send priority in the rfm22b driver so that PPM packets are top priority.

bb87e6390e Update ppm_fresh if we receive a new PPM packet in order to keep the 
rfm22b receiver supervisor happy.

a2d8544931 OP-931: adds -Wextra compiler option for the flight code, and makes the bazillion code changes required 
to make the flight code compile again. Needs careful review, particularly all the fixes for the
signed vs unsigned comparisons.

57552f4cc9 OP-932: Changed the clock syncronization to happen only on packts transmitted from the coordinator to the remote modem. The Tx finished time of the previous packet is now sent in the packet header. This is compared to the Rx complete time of that packet on the remote modem to calcualte the difference between two modems. This eliminates the need for ACKing, so ACKs were removed for PPM and status packet. 2013-05-04 16:50:08 +01:00
