cxadc

• Set device parameters using cxadc.parameters.*.parameter.
• Set group to allow non-root access to the device and sysfs parameters.
• Enable exportVersionVariable to export the git hash to the environment variable __CXADC_VERSION.

Note

Changes may require udevadm trigger to apply.

Example

{
    hardware.cxadc = {
        enable = true;
        group = "video";
        exportVersionVariable = true;

        parameters = {

                crystal = 40000000;
                level = 0;
                sixdb = false;
                tenbit = true;
                tenxfsc = 0;
                vmux = 1;
            }

            cxadc1 = {
