A multi-channel timing controller is designed to meet diverse needs of photoelectric detection systems for timing control. ARM and FPGA frame are used to design control core

which is beneficial to improve timing precision and at the same time assure flexibility of the system. A programmable smart LCD is used to design the user interface

making the human-system interactions more convenient and efficient. In addition

upper PC software can be used to communicate with the controller through a serial to Ethernet module

and the PC software is developed based on Lab VIEW. Experimental results show that the controller has a good performance in timing precision of 1 μs

long operating cycle of 24 h

response to external triggers

and remote control based on Ethernet.Thus

the controller has a high application value

especially in the poisonous and harmful environments.
