Hello
I'm doing my first steps in TinyOS and have sucessefuly write code to
comunicate with an rs232 device.
Did you used the technique presented at the MoteIV support to have access to
the UART because it is
also used by the radio. Besides that I also used USARTDATA.rxDone and it
worked, did you enabled the UartControl.enableRxIntr()?

Subject: [Tinyos-help] How to receive messages over the UART?
Hi,
I have connected a mote to a digital camera with a serial interface. I am
able to transmit to the camera using the UART but I am having difficulty when
trying to receive the acknowledgements it sends back. Ideally when a byte is
received I need an interrupt to be flagged to enable me to read and store that
byte of data. I believe this should be possible using the asynchronous event
USARTDATA.rxDone found in the HPLSUARTFeedback interface of the HPLUSART0M
module. Although I have wrote code that should work the rxDone event is never
signalled even when I am sending data to the receive pin on the UART. I have
ensured that the baud rate is set correctly and that the receive pin on the
UART is enabled. The code compiles without any problems so I don't know where I
am going wrong?
Any help would be greatly appreciated,
Cheers,
Steven
