Part 1: Warmup
Write an Embedded C program which implements a 3-Bit binary counter and displays
the value of the counter on the LED’s. If S1 is pressed the counter should count up once
per second. If S3 is pressed the counter should count down once per second. If neither
button is pressed the count should remain static.
Part 2: Driving Speaker using a Timer
The speaker is connected to P1.5. To make a sound the speaker needs to be driven with
a frequency within the normal range of human hearing (20Hz - 20,000Hz). Write code
to generate a frequency to drive the speaker at 1kHz using Timer0. Verify the frequency
using an oscilloscope on the speaker.
Part 3: Speaker Tuner
Write a C program which generates a tone of which the pitch is controlled by the potentiometer on the board. The frequency should increase as the variable resistor is turned
clockwise.
Part 4: Timer interrupt
Write a C program which generates a timer based interrupt every 300ms. When the
interrupt service routine runs a counter value should increase by one. This counter value
should then be displayed in binary on the 3 LEDs.
Part 5: External Interrupts
Write a C program that uses external interrupts to determine if a button has been pressed.
All of the pushbuttons should be capable of triggering the interrupt. The interrupt service
routine should be used to light up a different LED corresponding to the button that was
pressed (e.g. button 1 turns on LED1, button 2 turns on LED2, ect). The P1IFG register
allows you to work out which button has been pressed. The LEDs should stay on until
the next button has been pressed.

I have understood your requirements and project pretty well. I can make it with quality in reasonable price. Please come into the chatbox for further discussion regarding the project. Waiting for your first precious me Další
hi there, i can develop firmware for your requirements independent of target processor. I have relevant experience more than that this task deserves. But i am new to freelancer. please consider me...
I work as embedded engineer as every day job. I could do the work you are proposing. I need the schematic of the circuit, or the microcontroller name. best regards Federico
