  1. Hi Jeffrey, Sorry I should have mentioned that we are considering DAQHat, specifically, MCC 134 OEM. The only acceptable DAQ controller for us is ARM from either STM or NXP. We can develop such controller in-house but it's more efficient to buy COTS. Thank you!
  2. Hello to all, We would like to use a quantity of MCC OEM boards designed to operate under Raspberry Pi control. At this moment RpI are out of stock everywhere. Can anybody suggest replacement MCU? We want to avoid Linux and Python. RpI consumption is too high for use due to quantity.
  3. Hi zygot, I have to agree with you that lack of full schematic irritates, however, it's still possible to utilize it for one time projects. Besides, they provide a partial schematic covering ADC interfaces. Also, it might be possible to accomplish whatever the poster wants by using available software resources. I am not sure that he needs any HW design but configuration. I have this thing (14 bit version) and use it in my work mostly for measurements and as a signal source. Its ADC and DAC are excellent. My point that making custom hardware will triple the cost and development time.
  4. Hi herve, It is not clear what are you expecting to hear. Are you looking for a commercial module with firmware or just an option for your own design? There are a number of ICs from Analog Devices, TI, Maxim that satisfy your sampling rate requirements and resolution, for a example, ADC chips LTC2313, LTC2314. However, they require high frequency (>=40MHz) clock, thus, high frequency connector to the FPGA board. Personally, I think Avnet MicroZed board would be a good base for your design. Another option is to look at evaluation boards from ADC, DAC chip vendors. Typically, they are very good for learning capabilities of the product and recognizing gap we need to fill. Take a look at the Red Pitaya package. It might be overkill but has everything you might need. Good luck!
  5. Hi Jon,

    Would it be possible to share with me JTAG over USB schematic diagram used on Zybo board?

    On my custom card I want to combine UART and JTAG on a single USB connector. Digilent JTAG over UART-USB is very reliable and works seemlessly.

    Thank you.

      Hi @Notarobot,

      You will need to e-mail support.digilent@ni.com to discuss getting this information.

      cheers,

      Jon

      Hi @Notarobot,

      Not a problem.

      cheers,

      Jon
