My task is to make a tone generator that output the 7 basic tone:A,B,C,D,E,F,G,G# by pressing the corresponding input.I know how to write the code in assembly by using the timer register and write a delay function corresponding the notes frequency.My other task is to interface it with a Microchip 25040 EEPROM using SPI protocol, which I dont know what is the use of it.

My question is how to write the same code in C?because I need to combine the SPI initialization code with the tone generator code to burn it in 8052 microcontroller.

Any suggestion on how make this work is welcome.
