Hello all, I am designing an IR curtain with TX array on one side and RX array on another side. TX side controller and RX side controller are different not same. I am using timer on both side for synchronization but i am not getting results. I want to synchronize transmitter and receiver without any GPIO line. I want to synchronize it with IR -Tx and Rx sensor. If any one has idea how to synchronise it please help me.
Regards, Sagar
Hi Per Westermark,
I am using an 8051 controller,and with one controller i am handling 9 receiver on Rx side and there are 9 controllers serially with there 9 receivers on it.
On Tx side also i am using 8051 with 9 transmitter and 9 controller serially with there 9 transmitter on 1 controller. I am trying to save on electronics by flashing the individual beams in a sequence. On Tx side i am making 1st ir transmitter ON then make it off, then move to next ir transmitter and so on. After 9 successive ir transmitter i am sending ack signal to another controller to start its transmission in a sequence. On Tx side i am modulating beam so on receiver will come to know which Ir transmitter is on.
I am sensing ir modulated signal on reviver side. After one complete scan i am sending revived data from all 9 controller to PC for image formation.
In above case i am not able to synchronise Tx side and Rx side.
