AMC7834EVM: EVM interface board python support?

Part Number: AMC7834EVM
Other Parts Discussed in Thread: AMC7834

Team,

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 frost@ti.com and we can discuss what you are trying to do with the EVM.  There could be a simpler way to go about this.

    Thanks,

    Paul
