Button Debouncer
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
This example demonstrates using a button debouncer state machine to count the number of presses on the center button
|
|
on the basys3 board. The number of presses counted by the debouncer will be given on the two left most digits of the display followed by the count for the number of presses by the non debounced counter. You can reset the button counter
|
|
by pressing the up button on the board. To build the design first navigate to the additional examples directory:
|
|
|
|
.. code-block:: bash
|
|
:name: additional-examples
|
|
|
|
cd additional_examples
|
|
|
|
Then run make to compile the design:
|
|
|
|
.. code-block:: bash
|
|
:name: example-debouncer-basys3
|
|
|
|
make -C button_debouncer
|
|
|
|
|
|
At completion, the bitstream is located in the build directory:
|
|
|
|
.. code-block:: bash
|
|
|
|
cd button_debouncer/build/arty_35
|
|
|
|
Now, you can upload the design with:
|
|
|
|
.. code-block:: bash
|
|
|
|
openocd -f ${INSTALL_DIR}/${FPGA_FAM}/conda/envs/${FPGA_FAM}/share/openocd/scripts/board/digilent_arty.cfg -c "init; pld load 0 top.bit; exit"
|
|
|
|
The following is an example of the debouncer in action:
