adjust sound of piezo electric

I got a device with a piezo electric buzzer that is working quite well but i still get some backround noise and not the mzimum loudness. I just want to clear the sound to be perfect for the purpose of the device. A sample of sound can also be provided. I will provide the datasheet of the buzzer and buzzer.c file and all other files of the buzzer. You can test it with your equipment or just adjust the files as per datasheet and i test myself on the real hardware. The developer must have good knowledge of piezo transducer with a square wave and square wave rise time/fall time solution. I need this donw within 3 days.

PAYMENT: ALL money shall be paid upon completion of the job and after i download the file to the mcu and test it on the real hardware. If you require a milestone in advance do not bid. I need someone who knows in advance he will complete the job.

Habilidades: Programación en C, Ingeniería eléctrica, Electrónica, Microcontrolador, Diseño de sonido
