adamdunkels 3fa8ffda1a Moved the modules packetbuf, queuebuf, and packetqueue from net/rime to net/, since they are not Rime-specific 2010-06-14 19:19:16 +00:00
nifi 14b1bb9f57 Fixed to only use leds when DEBUG is set 2010-04-20 11:41:16 +00:00
adamdunkels 3670fac618 Bugfix: timing fixed 2010-04-08 18:23:24 +00:00
adamdunkels be117afe04 After a lot of tweaking and twiddling with the timing of the ContikiMAC code and the mechanisms in the CC2420 driver, things seem to work somewhat stable now - knock on wood! 2010-04-04 07:49:30 +00:00
adamdunkels a637ddaf4e Flush the rxfifo when turning off the radio instead of when turning it on. This seems to fix a bug that was seen in mspsim and seemed to appear on real hardware too. 2010-04-03 16:01:00 +00:00
adamdunkels c9ca5d61e2 Rewrote the pending_packet() function to check the FIFOP pin instead of the 'pending' variable - works must better on real hardware and is now supported by the latest mspsim 2010-03-31 19:08:56 +00:00
adamdunkels 4d5f112960 New return value for invidating a link-layer collision 2010-03-30 23:00:22 +00:00
adamdunkels 5e7f99a2c0 Reverted the removal of the code that checked the FIFOP pin before reading a packet - checking FIFOP is the correct way to do it. Also added TXONCCA for now, including new radio.h return values to indicate a link-layer collision. 2010-03-30 23:00:05 +00:00
adamdunkels a3a8c0e179 Safety check: only try to read a packet if it was preceeded by an interrupt (which sets the pending flag) 2010-03-19 13:18:53 +00:00
nifi ea090a60e6 Fixed to call the SLIP callback function also when using IPv6 2010-03-17 07:10:25 +00:00
adamdunkels 67b0170a43 Bugfix: don't care about FIFOP when reading a packet; if the radio rx had been turned off before a packet was read, FIFOP would be zero and the packet would be trashed 2010-03-16 18:10:09 +00:00
nifi 55e0fec37e * Changed to write keys to CC2420 RAM big-endian order 
* Fixed cc2420_aes_cipher() to wait for encryption to finish before reading result
 2010-03-15 23:04:54 +00:00
nifi e834562455 * Fixed FASTSPI_READ_RAM_LE to wait for tx end before reading 
* Added FASTSPI_WRITE_RAM_BE to write to RAM (big-endian order)
 2010-03-15 23:01:37 +00:00
adamdunkels 0035a70537 Reworked the locking code, which seems to fix a few bugs caused by the interaction with contikimac. Contikimac performs a CCA check in a preempting rtimer, which requires underlying code to properly call the GET_LOCK() macro. This fix seems to solve most problems, but there may be others left. 2010-03-14 22:45:20 +00:00
nifi 58c55340ed fixed to work with IPv6 2010-03-10 22:30:39 +00:00

adamdunkels cc7d3ae142 Reset CCA mode to default. Make sure that the radio gto switched on when reading RSSI; otherwise node will reboot because of watchdog 2010-03-09 13:18:16 +00:00
adamdunkels b9827d2b36 Bugfix: didn't correctly reset the pending flag when a packet was read from the radio 2010-02-25 16:06:44 +00:00
adamdunkels 4b04fdd328 Minor style fix 2010-02-23 18:26:26 +00:00
adamdunkels 1ee32c3074 Removed non-functional time synchronization code; added some experimental code for CCA checks (enabled CCA mode 1, a temporary development function for setting the CCA threshold); enable the possibility to switch off radio even if a packet is currently arriving 2010-02-23 18:24:49 +00:00
adamdunkels 5292005962 A null radio driver that does not do anything - useful in the native port and as a template for new radio drivers 2010-02-23 18:18:53 +00:00
adamdunkels 0b2b7bcdba Removed inadvertedly left-over include file 2010-02-18 23:52:34 +00:00
adamdunkels e34eb54960 A work-in-progress rework of the Contiki MAC and radio layers. The 
main ideas are:

* Separates the Contiki low-layer network stack into four layers:
  network (e.g. sicslowpan / rime), Medium Access Control MAC
  (e.g. CSMA), Radio Duty Cycling RDC (e.g. ContikiMAC, X-MAC), and
  radio (e.g. cc2420).
* Introduces a new way to configure the network stack. Four #defines
  that specify what mechanism/protocol/driver to use at the four
  layers: NETSTACK_CONF_NETWORK, NETSTACK_CONF_MAC, NETSTACK_CONF_RDC,
  NETSTACK_CONF_RADIO.
* Adds a callback mechanism to inform the MAC and network layers about
  the fate of a transmitted packet: if the packet was not possible to
  transmit, the cause of the failure is reported, and if the packets
  was successfully transmitted, the number of tries before it was
  finally transmitted is reported.
* NULL-protocols at both the MAC and RDC layers: nullmac and nullrdc,
  which can be used when MAC and RDC functionality is not needed.
* Extends the radio API with three new functions that enable more
  efficient radio duty cycling protocols: channel check, pending
  packet, and receiving packet.
* New initialization mechanism, which takes advantage of the NETSTACK
  #defines.

zhitao 93c748cc74 Bug fix for mysterious packet loss : check FIFO pin instead of FIFOP pin for any unread RX FIFO data; 
Added protection of packet timestamp across interrupts. Note that race condition can still occur as interrupts and self-scheduled reads of the RX FIFO interleave in certain unusual patterns. More investigation is needed.
 2009-12-11 18:32:54 +00:00
adamdunkels 6815e2a53f Code style fix 2009-12-05 11:26:20 +00:00

adamdunkels 8745235a79 Minor codestyle fix 2009-09-09 21:07:42 +00:00
nifi d4b619bcc5 Renamed SPI_WAITFOREOTxBUF to SPI_WAITFORTxREADY for clarity and generalized SPI transmission status checks to work with both AVR and MSP430 2009-09-07 11:31:26 +00:00
nifi 3a8ee769cb Changed to monitor the UART transmitter buffer ready flag instead of the UART transmitter empty flag. This almost doubles the speed of transmitting data to CC2420. Patch by James Brown. 2009-08-31 12:06:34 +00:00
nifi c81dbb6c89 Fixed problem with the radio driver changing transmission power to max when not specified at transmission. Also fixed bug where the lock was released when setting the transmission power. 
Thanks to Djamel Djenouri and Marcus Lundn for identifying the problem.
 2009-08-19 15:05:05 +00:00

* Added missing include
 2009-04-07 09:22:58 +00:00
adamdunkels 0076bfe8a5 Changed the name of the 'serial' module to 'serial-line' to signify that the module is about lines of data from the serial port, not individual bytes, and to make sdcc happy 2009-03-17 15:56:32 +00:00
adamdunkels 65eb5fd4e8 Renamed the rimebuf module to packetbuf to signal that the module is used outside of a pure Rime context (e.g., the sicslowpan code uses it). 2009-03-12 21:58:20 +00:00
adamdunkels f634ccfb3d Set transmission power based on packet attribute 2009-03-11 20:38:53 +00:00

joxe 673d73bfa3 added energest on all parts of leds API and some cleanup 2008-09-29 11:35:28 +00:00
adamdunkels 6a460fecdd There is problem with the CC2420 driver: under high traffic load the packets often get mangled in the receive FIFO. Not sure why this happens or how to best prevent it. As a temporary workaround, I've added an additional CRC16 check to the incoming packets. This eats two bytes from each packet, but at least protects against the erroneous packets we've seen quite a few of lately. The reception code was also cleaned up, which resulted in a smaller code size. 2008-08-26 21:44:03 +00:00
adamdunkels f58b387bd3 Code style fixes 2008-07-08 08:23:47 +00:00
adamdunkels 1f005b6299 Moved energest.{c,h} from core/lib to core/sys: power profiling is a system mechanism, not a library 2008-07-03 23:36:30 +00:00

adamdunkels 2c5964ef55 Changed default transmission behaviour to be to send without checking for channel activity first (in anticipation of radio API change that adds a CCA function to the radio API). General code cleanup. Added optional timetable profiling. Added simple_cc2420_get_channel() function, changed simple_cc2420_set_chan_pan to simple_cc2420_set_pan since we now have a dedicated simple_cc2420_set_channel 2008-01-23 14:57:19 +00:00

 2007-11-18 12:27:44 +00:00
