projects: eval-ade7978: example project
Example project for ADE7978 in chipset configuration with ADE7933/ADE7932, and ADE7923. Tested using the EVAL-ADE7978EBZ. The example includes measurments of the rms values. The example is tested with the AD-APARD32690-SL. Signed-off-by: Radu Etz <radu.etz@analog.com>
