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.

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 Lundén for identifying the problem.

2008-09-29 11:35:28 +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.
