Elnegm said:I think in your FPGA you to implement UART module to deal with the COM port in PC if ypu will send data from FPGA to PC,but if the FPGA only reciecve data from PC ,so you will need small FSM on your FPGA to recieve UART frame and extract data from it and but it into RAM ,in both case you need to write c code on your PC in order to use COM port and send and recieve
And this site to interface with serial
and this is open source for UART module get it from open coures site

Excuse me sir, im kinda confuse... you have posted the site to interface w/ serial but i still dont know how to implement things further... my question is, is there any exercise that i could follow step by step on implementing it... i dont know where to start...I have done so many research on the net but still i could not find one whom i could follow...all i want is to interface the spartan 3 to PC... what do i need? do i need to connect wire directly from PC to FPGA without any hardware schematics at the middle and then using hyperterminal in PC in sending data towards the FPGA but ofcourse the FPGA is program to receive data already... or is there a hardware for me to interface the PC to FPGA? if it is so, i dont know the schematic for this, i dont know how to do this thing... pls do help me sir... i really need your help for this... hope for your reply
