 | | RE: Extending IR communications
|
| Orient both RCXs so that they are pointing towards the ceiling. Set the RCX transmit power level to high (default is probably low power); there's probably some Lejos function to do this -- all it requires is setting one bit in an I/O register to 1. (...)

At the top of dir_write, you probably want to add: if (dir_tx_state == TX_ACTIVE) return -1; Or something to that effect, so you don't transmit a second message while a first is still transmitting, and so you have a way of (...)
