    ADC implementaion in DE2-115

    Hi, What is the difference between Ethernet MAC and EtherCAT. Can EtherCAT slave implementation is done using ethernet MAC. thanks, raja.

    ADC implementaion in DE2-115

    thanks for reply. Flibble, this is what i have an idea tell me whether am right. 1) Am using ADC implementaion to convert analog signals from Sensor to FPGA via serial interface. In DE2-115 board, i have an RS-232 with Trans receiver ZT3232E and sensor has an RS - 232 at other end. So, can...

    ADC implementaion in DE2-115

    you r right mrflibble. WM8731 is used for ADC purpose. For EtherCAT implementation , do i need to have a EtherCAt controller from Bhakoff or we can just implement a EtherCAT slave. In ethercat slave case, is there any example available. thans, raja.

    ADC implementaion in DE2-115

    Dear flibble, The sampling frequency provided in WM8731 is 8 - 96 kHz. As you said, through I2c we have very slow bit rate, and i think to control the shaft of motor continuously we need high bitrates. P.S: You are right abt serial interface and am sorry it was I2S not I2c. thanks, raja.

    ADC implementaion in DE2-115

    Actaully am already implementing SPI interface between the FPGA board and TI microcontroller. Thats why, i need to look for any other possiblities. In project is like data aquisition from voltage detection sensor --- FPGA --- TI controller. Later motor control using TI. So, in between FPGA --...

    Need Verilog/VHDL code for ADC and DAC

    Re: ADC hi, in my application, using DE2-115 Cyclone IV FPGA board which has 24 bit Audio CODEC ( WM8731 from wolfson ) using I2C and sampling frequency if 8k to 96kHz. ADC is used for data aquisiation from Voltage detection sensor and save in dual port ram. thanks, vrv.

    ADC implementaion in DE2-115

    Hi again, Thanks for reply. Actually its I2c i think, am attching the datasheet provided along with the board. If it so, i need to implement ADC using I2c. am i right. A query, is ther a possiblity of Implementing with EtherCAT slave. thanks, raja.

    ADC implementaion in DE2-115

    Hello Mr flibble, thanks for your reply, and sorry for replying lately. CODEC is 24 - bit encoder/decoder. In dev board manual it is mentioned as, board has 24-bit audio via Wolfson WM8731 CODEC. In Wolfson WM8731 Codec features are Audio performance -- ADC SNR 90 dB at 3.3 V. sampling...

    ADC implementaion in DE2-115

    Hello, I am newbe to FPGA, we are using DE2-115 Developmental board. For a task we need to transfer data from sensor to DE2-115, for which we need ADC. In DE2-115 user manual we can see Audio Codec ( 24 bit), can we use this as an ADC, please let me know if there is an example or any pdf...
