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.

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

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
