Hi,
I'm trying to adapt the Oscilloscope exemple, present in TinyOS 2.1.1, to my
purpose. Instead of reading from a sensor and transmit those readings, I want
to read from serial using pins 2 and 4 of the expansion port of a telosb mote.
If I use the Oscilloscope example without any change, my test scenario works.
When I introduce my changes, the event UartReceive.receive is never called. The
source is sending data, as I tested it with a notebook.
My changes came from the BaseStation example, and are the following:
configuration OscilloscopeAppC { }
implementation
{
( ... )
components ActiveMessageC as Radio, SerialActiveMessageC as Serial;
OscilloscopeC.SerialControl -> Serial;
//OscilloscopeC.UartSend -> Serial;
OscilloscopeC.UartReceive -> Serial.Receive;
OscilloscopeC.UartPacket -> Serial;
OscilloscopeC.UartAMPacket -> Serial;
}
module OscilloscopeC @safe()
{
uses {
( ... )
interface SplitControl as SerialControl;
//interface AMSend as UartSend[am_id_t id];
interface Receive as UartReceive[am_id_t id];
interface Packet as UartPacket;
interface AMPacket as UartAMPacket;
}
}
implementation
{
event void Boot.booted() {
uint8_t i;
for (i = 0; i < UART_QUEUE_LEN; i++)
uartQueue[i] = &uartQueueBufs[i];
uartIn = uartOut = 0;
uartBusy = FALSE;
uartFull = TRUE;
( ... )
if (call SerialControl.start() != SUCCESS)
report_problem();
}
event void SerialControl.startDone(error_t error) {
event void SerialControl.stopDone(error_t error) {}
event message_t *UartReceive.receive[am_id_t id](message_t *msg, void
*payload, uint8_t len)
{
message_t *ret = msg;
call Leds.led2Toggle();
atomic
if( reading != NREADINGS )
{
local.readings[reading++] = msg->data[0];
}
return ret;
}
Looks like the mote isn't reading from UART0TX/ UART0RX pins. What may be still
missing?
Thanks in advance!
Best regards,
