Trouble is, still, when I connect I2C to the Telos, no radio messages
are received. We measured some voltage on a pin (connected to our
I2C level converter, aka Philips Level Translating I2C Bus Repeater)
that the radio presumably shares - is this the problem? Should we
use a diode to block voltage going back to the Telos?
Have you released the I2C resource when you finished using it?
I presume so, e.g.
// this when we get I2C access granted
event void CmdIO.granted( uint8_t rh ) {
result_t r;
buffer[0] = lcd+1;
r = call I2CPacket.writePacket(rh,128,1,buffer);
if (r != SUCCESS) call CmdIO.release();
}
event void I2CPacket.writePacketDone(uint16_t addr, uint8_t len,
uint8_t* data, result_t s) {
call CmdIO.release();
call Leds.redToggle();
}
