I'm a bit new to fpga-s. I need help or sample code (vhdl if possible) for the A/D module.
I need a controller that initiates conversion and stores the data in a register or variable.
If you look at the users guide you will see that the Spartan 3e kit already has the code to control the Linear Tech A/D that is on the board. All you need to do is feed the analog signals to the preamp that is connected to the header on the board.
The FPGA will control both the preamp and the A/D. Once the data is converted it is brought into the FPGA via pin N10.
I'm trying to use adc on the spartan 3e now, but I have some problems I couldn't solve. If you find some documents and codes about this subject could you give me?
