AMC7834EVM: EVM interface board python support?

Part Number: AMC7834EVM
Other Parts Discussed in Thread: AMC7834


I use the interface board for the AMC7834 demo board to control the chip on my board. Currently I use your GUI to talk with the interface board.

 My question is if I could talk with it by software, like Python? Outside of the GUI for automation purposes.

Do you have any manual for this?

What I want to do is just control the DAC and change its voltage output.

  • Update:

    In fact, I don’t need to talk with your EVM board now.

    I need talk with two AMC7834 on my own board.


    Let’s forget Python for a moment.

    My first question is if your interface board could talk with two AMC7834?

    (There is two CS to decide which one to talk with, or use a GPIO as CS?)

  • Hi Julio,

    You could use an external SPI generator to talk directly to the EVM.  If you would like to use the SDM-USB-DIG to talk to both you can use 2x SDM-USB-DIG devices, which can technically work.  The problem is that the SDM-USB-DIG uses a COM port communication that is a bit nuanced.  We have a LabView library for it, and as you are a TIer we could share the source code with you if you would like.  Reach out to me at and we can discuss what you are trying to do with the EVM.  There could be a simpler way to go about this.
