The

ADC

tab provides the options to configure ADC channels and protection settings in the respective parts.



Toolbar​

The

ADC

tab toolbar contains

Add

and

Remove

channel buttons. The

Remove

button is active only for the last channel on the list.



ADC channels table​

ADC​

  • Triggered source

    – The ISR trigger priority. The options from the dropdown menu:

    Control loop

    or

    Scheduled

    . For details, see the middleware documentation:

    https://github.com/Infineon/mtb-pwrconv

  • Channel

    – The channel name is auto-set or custom. The first channel configuration is mandatory for the

    Infineon control loop

    . The controlled output parameter –

    Vout

    , and the channel name is defined accordingly

  • Units

    – The units of the respective channel. You can select from the dropdown menu:

    V

    (volts),

    A

    (amperes),

    º

    (degrees), or

    Custom

    .

  • External gain

    – The resulting factor of the signal conditioning on the electrical quantity: either attenuation or amplification. The value range is 0.001 - 100.

  • Pin

    – Displays the pin assigned to the channel. The pin assignment can be changed from the Device Configurator

HW Protection​

  • Underlimit/Overlimit

    – The protection from the under/over crossing ADC range. Check a corresponding check box to enable bottom/top boundary protection.

  • Value (ADC equivalent)

    – Represents the voltage of the native electrical quantity at the MCU pin after conditioning. The maximum supported ADC value is 3.3 V and the minimum – 0V.

DMA

Enables the HW DMA transfer from the ADC register to SRAM memory. Check this box for the selected channel. This option is available if the triggered source is the control loop.
