To developpe the program in assembler for the microcontroller Motorola 68HC11, we've used a simulator:
To load the program to the microcontroller, we can use a program as JBUG11 and run it.
You can download the assembler program we've done. The final progam have a range between 40 decibels and 120 decibels with a the peak value that is lightened a few second and fall slowly to the current value (except if a new peak has overcomed the old one). One level correspond exactly to one dB.
