    Using VADC_GROUP app gives error in VADC around 2048

    Hi,

    Using the VADC_GROUP app in Dave 4.3.2, the XMC4800 ADC measurement gives an error in the area around 2048. (see attached image).
    Using the simple ADC_MEASUREMENT app or the ADC_MEASUREMENT_ADV app, this error does not appear.
    I tested this on the XMC4700_XMC4800_Relax_Kit_Series-UM-v01_02-EN and the XMC4300_Relax_Kit.pdf-UM-v01_01-EN. Both evaluation boards behaves the same.

    Please can anybody tell me what I do wrong and how to solve this problem?

    The final goal is to sample 16 channels with 100kHz time equidistant sampling rate and storing the ADC values to RAM.
    When one of the signals crosses a predefined limit, an interrupt must be generated. Is for this kind of applications an example project available?

    Regards,
    Gerrard
