Hi guys, I am designing a circuit that will convert 12V signal into digital through a Comparator and that needs to be read by FPGA. (1) If I don't use a common GND for the comparator and the FPGA, do I have to use Differantial inputs? (2) Which IO Standard do I use, and where can I get their specifications (3) Can someone advise me o

I have constructed the vhdl code for master(FPGA) and slave (adc). What are you trying to achieve? If you want to control the adc, you have to design a SPI master interface. A vhdl code for the slave would be needed only to simulate the slave's behaviour. (...)
hi, i want to interface adc with a cpld ,how can i do the same
Hello; I want to use the adc on spartan 3e kit. I think I need to use SPI interface to connect the adc to the FPGA. I wonder if I can find a vhdl source code for using adc with SPI interface. Please help me... Thanks...
I cannot get the following code to produce the correct results of a subtraction and I'm not sure what is wrong with it. Current is an input from an adc that is in two's complement form. The clk is the same for both the adc so that I should be clocking in a new sample at the same rate of the (...)
