Hello friends.
I am a beginner on the FPGA side, I am having troubles making the fpga( Spartan-3e Starter kit) to communicate with my PC. UART is easy to implement, so i choose to implement UART for my purpose.
After writing UART in verilog,( At same time i was learning verilog also) i simulated the results and it behave as expected in simulation. but when i programmed it into FPGA it doesn't work. I don't know why?
I am posting my code for receiver and transmitter.

Please let me know if anybody knows link to videos or tutorials on implementing UART or Ethernet.

Do you have your pinouts mapped properly?
Is your hardware working?
Did you connect power?
Did you look at signals with a scope?
Are your speeds correct?
