Piezo Speaker

Posted by: ben in FPGA, tags: ,

Great, the FPGA board has a piezo speaker soldered. This is the next funny component to drive. The device is connected with one wire, where the FPGA has to send a pulsing signal to it. Typical this signal will be generated by a frequency generation module. The sending frequency of the implemented module can be increase and decrease by the switches on the board, by hitting this switches to a good beat the device generated a nice sound.

– Again, if you want to have a look into the VHDL code, just write me an email.

    Hi… I am working on a project that involves the Xilinx ML506 which has the embedded piezo speaker. However, I don’t really know how to specify different tones OR create different tones. Pleas if you could send me the code I would very much appreciate it!
