Configurable Key Click Tone

4-8 Chapter 4: Programming

The FPGA has the ability to sound a short chirp whenever a key is pressed, providing auditory feedback to an operator of the keyboard. This auditory feedback is optional. The FPGA may be configured to make the sound or not to make the sound, depending on the particular application.

USB DynaKey Tone Frequencies

The frequency is transmitted to the FPGA as a Note Number. Note numbers are equivalent to specific frequencies. The note number sent to the FPGA is selected by rounding the requested frequency to the nearest frequency number given by the table of Note Numbers (N) and Frequencies (freq) listed in the following table.
