George Oikonomou 060b00c4b5 Use TRICKLE_TIMER_IS_STOPPED in trickle_timer_stop() 2013-09-30 12:37:03 +01:00
George Oikonomou 2957d44ff8 Merge pull request #352 from lab11/cc2538-spi-driver 
Added SPI driver for CC2538
 2013-09-28 13:25:17 -07:00
Brad Campbell e2af903d05 Added SPI driver for CC2538 
This uses the core/dev/spi.h header and implements the spi_init()
function and the various macros for SPI operation. ssi.h contains all of
the register locations and information.

This implementation is not very versatile, mostly because I don't how to
make it flexible in the contiki system. It supports pin muxing for the
four spi pins, but other than that picks sensible defaults.

The SPI macros (like SPI_READ()) are defined in
cpu/cc2538/spi-arch.h. In order to use the SPI driver, add the following
includes to your project:

    #include "spi-arch.h
    #include "dev/spi.h"

Small fixes to networking files

Nicolas Tsiftes 43b5425493 Cleaned up various fragments and fixed a compilation error that occured when switching metric container. 
Fixed a wrapping problem in the ETX EWMA calculation.

Corrected the multiplier of the link metric, and simplified the configuration
so that the user does not need to specify the multiplier.

Oliver Schmidt 4772455a9a Merge pull request #358 from oliverschmidt/master 
Optimized 6502 Ethernet drivers.

Oliver Schmidt 2263c1aa55 - Optimized LAN91C96 driver for speed and size. 
- Speed: The primary byte copy loops are reduzed to the bare minimum by adjusting the base pointer 'ptr' and loop register 'y' in such a way that the 'y' overflow matches the low byte of the loop size.

- Introduced a loop for setting the MAC address.

Additional minor fix:

- Properly start self modification with first location.

Oliver Schmidt ea08635ca4 Optimized CS8900A driver for speed and size. 
- Speed: The primary byte copy loops are reduzed to the bare minimum by adjusting the base pointer 'ptr' and loop register 'y' in such a way that the 'y' overflow matches the low byte of the loop size.

- Size: Factored out all repeated code into subroutines. Introduced a loop for setting the MAC address.

Additional minor changes:

- Activate frame reception as last step of initialization after CS8900A configuration.

- Properly set internal address bits used by the CS8900A.

Initialize tcpip process before resolver process.

Oliver Schmidt 6fc83cf601 Initialize tcpip process before resolver process. 
Since introduction of mDNS (f145c17039)
the resolver process initialization depends on the tcpip process
already being initialized (because of the call to udp_new()).

Adam Dunkels bfd7e5f25b Fixed a few bugs in the route handling code. While bughunting, rewrote parts of the code to make its intention clearer. Also added a bunch of comments to make the logic of the code more evident. 2013-08-19 17:48:32 +02:00
Adam Dunkels 8dc4e46968 Check if the nexthop neighbor for a given route has disappeared. If so, we drop the route too. If we happen to be the RPL root, we also initiate a global repair as the neighbor may moved. 2013-08-19 17:48:32 +02:00

Adam Dunkels d830e9df3f Implement forwarding error handling: if a packet changes direction, we set the FWD_ERR flag. If we see the FWD_ERR flag, we drop the route that we sent it to. If we are the root node, we also initiate a global repair. 2013-08-19 17:48:31 +02:00
