Good evening to all. I face the same case as pradeepkumar481 that posted on 18/11. I am using the ADS7861 (a quite new ADC that somemore u can request from Texas Instrument) and need to connect to FPGA DE2 board. I have been told to use a SPI on this. However, i have no idea what is the SPI and how to connect it. SPI is a synchronous interface fro serial communication according to wikipedia. Is that a chip??? Since it consists of Master and slave structure, is that i need to use VHDL code inside my FPGA board and a chip between ADC and FPGA (if SPI is really a chip). then FPGA acts as a master and the chip between FPGA and ADC acts as a slave. Is it? I really cant figure it out as ADC cant be input the VHDL code.
For another assumption of mine, is that i just need to input both master ans slave VHDL code inde FPGA board . Then the FPGA acts as Master and connect to slave which is inside FPGA too. Then the slve is connected to ADC, which is ADS7861 in my case. Is it?
I need to design the VHDL code for these in order to connect ADC and FPGA. I cant process as i struck here. Can somebody help me?
