Welcome to our site! EDAboard.com is an international Electronics Discussion Forum focused on EDA software, circuits, schematics, books, theory, papers, asic, pld, 8051, DSP, Network, RF, Analog Design, PCB, Service Manuals... and a whole lot more! To participate you need to register. Registration is free. Click here to register now.
You can use simulation tools to check and verify that your code is correct or not and observe your outputs as well...
For inout pins, check for tri-state buses...
Re: i2c master mode is done.But can i get anythin in spartan
simulation is proper.but i want to see it on hardware.the problem is that i have done only master mode.
and my SDA and SCL lines are inout.
so how will i assign in spartan 3 E?
Re: i2c master mode is done.But can i get anythin in spartan
Most of GPIO pins for spartan 3E is IO buses. Check for GPIO's at Spartan 3E datasheet. You need to have ucf file and assign the proper values(which GPIO you use has a ucf definition) at ucf file...
And what's your harware that communicates with FPGA.. You need to have a physical connection with your FPGA and your hardware... You need to connect your hardware's SCL and SDA to the FPGA GPIO...
