How to Use QTouch Studio For Pin Configurability

The following steps describe the details on how to use pin configurability for QTouch Acquisition method:

1. 1.

   Open AVR QTouch Studio .Enable the Design Mode Radio button on the left hand side of the screen.

   Figure 1. Selecting the Design mode in the AVR QTouch Studio
   
   
2. 2.

   Go to File Menu option and click New Design .

3. 3.

   In the Create New Design Window, give the Project name and Kit Technology (QTouch in this case) and and Number of sensors (Keys/Rotors/Sliders) and click Create Design.

4. 4.

   After Creating Design, the new screen pops up which shows all the sensors which have been created.

5. 5.

   Now Go to Tools->Pin Configuration Wizard.Pin configuration .

6. 6.

   Pin configuration Window will pop up with the information on the usage of the tool. Click Next to proceed to the configuration.

7. 7.

   Select the MCU and click Next as shown below.

8. 8.

   Select the SNS and SNSK ports needs for the design and click Next.

9. 9.

   Select the pins used for the design and click Next .

   If there is error in the selection of the pins (Ex: conflictin pins used), a red marker will be appear and the user cannot proceed to next step in configuration until the user has done the correct pin selection.

   Now once the selection is done without errors, Click Next.

10. 10.

    In the New Window Screen, the code is shown on the screen.QTOUCH_STUDIO_MASKS needs to be enabled in the project option or in touch_ config.h file. And in the main.c file, this code SNS_array and SNSK_array needs to be copied from here and put under QTOUCH_STUDIO_MASKS macro as shown below in the main.c file.

    #ifdef QTOUCH_STUDIO_MASKS
        SNS_array[0][0]=0x09;
        SNS_array[0][1]=0x22;
        SNS_array[1][0]=0x00;
        SNS_array[1][1]=0x00;
        SNSK_array[0][0]=0x14;
        SNSK_array[0][1]=0x88;
        SNSK_array[1][0]=0x00;
        SNSK_array[1][1]=0x00;
    #endif
