Library functions for using the switches are contained in the Basys MX3 library pack, SWT library. However, the user can easily use the
switches without the SWT library, as presented above.
4.3. Shared Pins
As shown in the connectivity table above, SW7 driving signal is shared with the TRIG_2 signal in 2×15 Pins Debug Header.
5. User Buttons
There are five buttons on the board, labeled BTNU, BTNL, BTNC, BTNR, BTND both on the board and in the schematic, attached to five
digital IO pins of PIC32. Reading the buttons is done by basic access to an input IO pin. Read more details in Digital Inputs and Outputs
chapter.
Figure 5.1 shows the way the buttons are electrically connected on the Basys MX3.

All the pins must be defined as digital input: their corresponding TRIS bit must be set to 1, and analog function must be disabled for pins
corresponding to BTNU, BTNL, BTNR, BTND.

Do you have a question about the Basys MX3 and is the answer not in the manual?
Questions and answers
I m not able to use the basys mx3 with recent version of mplabx (6.x). The debugging tool does not show in the list. U of Sherbrooke
If the Digilent Basys MX3 board does not appear in the list of debugging tools in MPLAB X version 6.x, you can try the following steps:
1. Ensure the board is connected via the DEBUG USB connector.
2. Verify that the correct device (PIC32MX370F512L) is selected during project setup.
3. Make sure all required drivers are installed for the Basys MX3 board.
4. If the tool still does not appear, manually select it under the Licensed Debugger group.
5. If unavailable, consider using MPLAB X IPE to program/erase the microcontroller, though it does not support debugging.
If the problem persists, the version of MPLAB X may not fully support the Basys MX3 debugger integration. In this case, try using a different MPLAB X version or contact support for updates.
