After installing the required third-party tools and generating microcontroller abstraction layer (MCAL) demo project, you must customize the MCAL demo project for the motor control application. To customize the project, you configure the peripherals such as analog‑to‑digital converter (ADC), digital input/output (DIO), and universal asynchronous receiver/transmitter (UART) along with their interrupt configuration, interrupt priorities, memory allocation, and port configurations.

After you generate the MCAL configuration in EB Tresos Studio, implement these configuration settings. For a visual walkthrough of the configuration settings, play the video.

Configure ADC

These configuration steps in EB Tresos Studio enable MCAL drivers to generate accurate, time‑synchronized analog measurements required for the control algorithms of the motor control application.

1. To configure ADC parameters in the Adc tab, in the DemoApp project, expand Adc (Version #) and select Adc.

2. To enable the ADC read group for synchronized and fast analog sampling, in the General tab, select the AdcReadGroupApi parameter.

3. To configure the ADC hardware trigger parameters, in the AdcHwUnit tab, double-click the index entry of the AdcHwUnit_0 parameter. In the AdcHwUnit pane, double-click the AdcChannel tab. For this motor control example, you do not need channel 1. To delete this channel from the configuration, select AdcChannel_1 and click the Remove selected elements button .

   To configure AdcChannel_0, double-click the index entry of the parameter. In the General tab of the AdcChannel pane, set the AdcAnChannelNum parameter to G0CH0.

   To navigate to AdcHwUnit tab, click the Navigate one container upward button .

4. The motor control example does not use any software triggers. To delete software triggers, in the AdcGroup tab, select AdcSWGroup, and click the Remove selected elements button .

5. To configure ADC hardware group parameters, select the index entry of the AdcHwGroup parameter. In the General tab of the AdcGroup pane, configure these settings.

   • Set AdcGroupId (dynamic range) to 0.

   • Set AdcStreamingBufferMode to ADC_STREAM_BUFFER_CIRCULAR.

   • Set AdcStreamingNumSamples (1 —> 255) to 2.

   • Set AdcHwExtTrigSelect to ADC_TRIG_9_GxREQTRJ_GTM_ADCx_TRIG1.

6. Because this example does not use channel, you must delete all channel 1 parameters.

   • In the AdcGroupDefinition tab, select the index entry 1 and click the Remove selected elements button .

   • In the AdcResRegDefinition tab, select 1 and click the Remove selected elements button .

7. The motor control example uses the GTM trigger for the PWM block from the Embedded Coder^® Support Package for Infineon^® AURIX™ TC3x Microcontrollers. To delete the GTM trigger configuration in EB Tesos, in the GtmTriggerTimerConfig tab, select the GtmTriggerTimerConfigGtmTrigger parameter, and click the Remove selected elements button.

   To navigate to Adc tab, click the Navigate one container upward button twice.

8. To add a new ADC hardware module entry, in the AdcHwUnit tab, click the Add new element with default values button . This creates a hardware module with the name AdcHWUnit_1.

   To configure the parameters of AdcHWUnit_1, double-click on its index entry.

   • In the General tab of the AdcHwUnit pane, set AdcHwUnitId to HWUNIT_ADC3.

   • To configure the channel parameters of the new ADC hardware module, in the AdcChannel tab, double-click the index entry of Adc_Channel_0. In the General tab of the AdcChannel pane, set AdcAnChannelNum to G3CH0

   • To avoid naming conflict with the channel parameters of AdcHWUnit_0, at the top of the AdcChannel pane, rename Adc_Channel_0 to Adc3Channel_0.

     EB Tresos opens a dialog box when you rename any parameter. To update the parameter references, in the Adapt References dialog box, select Yes.

   To navigate back to the AdcHWUnit_1 tab click the Navigate one container upward button .

9. To configure the ADC group parameters of AdcHWUnit_1, in the AdcGroup tab, double-click on its index. In the General tab of the AdcGroup pane configure the following settings.

   • Set AdcGroupId (dynamic range) to 96.

   • Set AdcGroupAccessMode to ADC_ACCESS_MODE_STREAMING.

   • Set AdcGroupTriggSrc to ADC_TRIGG_SRC_HW.

   • Set AdcStreamingBufferMode to ADC_STREAM_BUFFER_CIRCULAR.

   • AdcStreamingNumSamples (1 —> 255) to 2.

   • AdcHwExtTrigSelect to ADC_TRIG_9_GxREQTRJ_GTM_ADCx_TRIG1.

10. To add hardware triggers, in the AdcHwTrigSignal tab, click the Add new element with default values button .

    In the AdcGroupDefinition tab, set AdcGroupChannel parameter of the 0 entry to /Adc/Adc/AdcConfigSet/AdcHwUnit_1/Adc3Channel_0. To navigate back to the Adc pane, click the Navigate one container upward button twice.

11. To configure the memory allocation parameters of the ADC, in the DemoApp project, expand Mcu (Version #) and select Mcu.

    This motor control example uses the GTM trigger for the PWM block from the Embedded Coder Support Package for Infineon AURIX TC3x Microcontrollers. Therefore, you must delete the GTM trigger configuration in EB Tesos. In the McuHardwareResourceA tab, double-click the index entry.

    In the McuGtmAllocationConf tab of the McuHardwareResourceAllocationConf pane, double-click the index entry 0.

    In the McuGtmTomChannelAllocationConf tab of the McuGtmAllocationConf pane, double-click the index entry 0.
