A/D Conversion on SAMA5D3 Xplained

Former Member

I have enabled A0-A2, but if I try to read the raw voltage using a cat of the Voltage0_raw file, I get a timeout.  Same thing for chan 1 and 2.

I can see that the channels have been enabled by doing a cat of the voltage_en files.  Is there further setup required?

  • Hello James,

     

    It's much better to put questions in a suitable group and mark them as questions (rather than post them as blogs).

     

    I can't help you with this because you don't provide anything like enough information.

     

    What dev tools are you using, I use and  program micros pretty much 100% of my time but the phrase "using a cat of the Voltage0_raw file" means nothing to me - I suspect it might some kind of Linux dependent reference in which case you will need to tell us exactly which OS you are running. Adding any relevant scripts and code would help.
