sample project specification:

This project will test basic programming competency in working with PIC processors. It will consist of a transmitter module (connected via serial port to a desktop PC) and a receiver module. The computer will issue commands to the transmitter module, which converts information to IR (infrared) to be received by the receiver module and displayed on an LCD screen. Certain commands may activate a LED on the transmitter module and receiver module.

The purpose of this project is to check the following understanding of working with PIC processors:
- transmit and receive of IR data
- being able to connect multiple unrelated hardware together for communication
- the ability to have multiple processes using interrupt routines
- the ability to dim LEDs

Details:
Transmitter:
PIC processor: PIC12F1840
Voltage input: 5V
Input is SERIAL at 9600 baud from PC (you can use a USB to serial adapter)
PC should have a terminal software (example: putty) where user's keystrokes will be output to the serial port.
Transmitter will take serial input and convert it to infrared signal, 940nm LED, modulated at 38KHz (0 bit is 38KHz output, 1 bit is no output)
There will be a single LED on the transmitter module. The numbers on the PC's keyboard will trigger various levels of LED intensity. For example: typing "0" will result in the LED being off. Typing "9" will cause the LED to be at 90% duty cycle PWM. Typing "5" will cause LED to be on at 50% duty cycle PWM. The frequency of the LED PWM shall be 1000Hz exactly.

Receiver:
PIC processor: PIC16F1827
Voltage input: 5V
Input is a IR receiver connected to the serial port. The IR receiver will demodulate 38KHz signals and output a serial signal connected to the PIC's RX port. There is a 16x2 character LCD display connected to the PIC processor. The LCD display will display all keystrokes sent by the transmitter in ASCII symbols. For example, the user types "A" on the PC's terminal, the user will see "A" displayed on the LCD screen. As a user types more characters on the PC, these characters will all be echoed on the LCD screen in sequence. When 16 characters are filled up on the first row, the characters will start to appear on the 2nd row. When the 2nd row is filled up with characters, a clear screen will happen and new characters will appear from a blank screen starting from the first row. There is also a LED connected to the receiver, it will behalf EXACTLY the same as the LED on the transmitter, example: if the CPU receives a "9" character, the LED will output at 90% duty cycle with a 1000Hz PWM.

Overall the finished project should behave like this:
1. Any characters typed on the PC's terminal should be displayed on the LCD screen of the receiver. Characters can be limited to a-z, A-Z, and 0-9, and !@#$%^&*()
2. Characters "0" to "9" will control LED intensity on BOTH transmitter and receiver modules.

I estimate this project to take no more than 2 weeks:
2-3 days to understand PIC and learn the programming environment.
1 day to draw the schematics / put together the test platform on breadboard
4 days of programming
1 day of testing
