Frequency generator
Digital Project EITF40
by
Robert Walther
In this project I developed a frequency generator based on a microcontroller.
This frequency generator provides
four signal types:
sinus, triangle, sawtooth and rectangular
with variable duty cycle.
The frequency scale goes up to 10kHz in 1Hz steps. Higher frequencies are possible with
reduced signal quality.
A single line LCD is implemented to
show the generator parameters which can be set easily by four push buttons.
The learning targets of this project
were:
- devise project requirements that
are possible to realize with given tools and electronic devices
- create a schematic of the system
that fits to the requirements
- build up the hardware on a strip
board
- implement the functionalities by
developing a program for the microcontroller
