Hi Miklos,
Thanks for the speedy response. My entire project is quite large... is there
any specific portion/part I can extract that would be more useful ?
The portion of code I initially posted is from RF230DriverLayerP.nc
tasklet_async command error_t RadioSend.send(message_t* msg)
{
uint16_t time;
uint8_t length;
uint8_t* data;
uint8_t header;
uint32_t time32;
void* timesync;
if( cmd != CMD_NONE || state != STATE_RX_ON || !
isSpiAcquired() || radioIrq )
{
FormatDbgStr("FAT :
cmd=%d,st=%d,spAq=%d,rIrq=%d\r\n",cmd, state,isSpiAcquired(), radioIrq );
return EBUSY;
}
...
...
...
}
Thanks,
Lewis

Can you post your code too? Miklos
