Synopsis
At the very beginning of this course, we decided to
work on a digital project that was to build a frequency generator. In
order to achieve that, we worked with different components: the microcontroller
ATMega16, the digital-to-analogue converter D7011c and the LCD screen
GDM12864H. The two main tasks of the project were to wire all the components
with each other so that we can generate a working communication at first and
then to program the microcontroller. With the final product it is possible to
create three types of signal: a sine, a rectangle and a triangle wave. The
range of frequency generated goes from 2.5 Hz up to about 860 Hz.
