ADC and DAC pmod

Former Member

i want setting up ADC and DAC   Peripheral Module at the same time on JA and JB on zedboard .  maxim's ready project file is( http://content.maximintegrated.com/en/design/tools/applications/evkit-software/index.mvp/id/1064) for 15 Peripheral Module that every time just one pmod can use, can you help me that how do i change  maxim's ready project file that ADC and DAC setting up whit together at the same time ?

    The Maxim demo is just a project to let you try out any one of the PMOD modules in their 'Analog Essentials' evaluation kit. Each of the PMOD modules can be plugged into either the JA or JB PMOD connectors on the ZedBoard and, as you suggest, you can connect one of the DAC modules to one of the PMOD connectors and the ADC module to the other.

     

    The multiplexed arrangement used in the Maxim demo is pretty complex. I would suggest instantiating an AXI I2C IP core in the Zynq PL (Programmable Logic) section for the MAX11205 ADC PMOD and either a second AXI I2C IP core for the MAX5825 DAC PMOD or a Quad AXI SPI IP core for the MAX5216 DAC. You can use the Zynq Concept Tools and Techniques tutorial, or one of the other tutorials on the ZedBoard Reference Design / Tutorials page: http://zedboard.org/support/design/1521/11 for an example of how to add IP cores and constraints to a basic Zynq design.

     

    Then you can use the software code provided in the Maxim demo software as an example of how to program and exercise the ADC and DAC PMODs. You could also look at the AXI I2C and AXI Quad SPI core code examples provided in the Xilinx SDK. But you will need to write your own software to operate both PMODs at the same time.
