Hello again, I want to learn how to use infrared sensors with this development board. I have seen this video, and I find very interesting.

http://www.dailymotion.com/video/xywv2n_how-to-interface-ir-sensors-lcd-display-with-fpga-devices-using-verilog-hdl_tech

I'm working on a project at the university, which is to count how many people are inside an office. I count how many people come and how many go through infrared sensors to interface with Spartan development board Elvert.

Could you please give me some ideas?
This post will discuss how to use the Seven Segment LED displays on the Elbert V2 Development Board from Numato Labs.  If you haven't been following the earlier posts then please start at the beginning here: Elbert V2 VHDL Tu...

Pablo, 

That video shows a simple IR receiver setup to measure obstruction.  The analogue electronics is a simple comparator being read by the FPGA.  Why use an FPGA?  It would be quicker and more simple to use a microcontroller for this purpose.  It would take considerable time to learn how to interface an LCD display with the Elbert V2 development board also...however the onboard LEDS could be used to provide the same effect.

Thats excellent, thank you very much.
This post continues on from the previous post on controlling the Seven Segment Display and using counters on the Elbert V2 Development board.  If people haven't seen that post then it can be found here: Elbert V2 FGPA tutoria...
