| =Lab Experiments=
| |
|
| |
| The experiments in this course are based on the project [[Embedded Systems Experiments for the Telecommunication Engineering Undergraduate Program]].
| |
| See this page for the [[Embedded_Systems_Experiments_for_the_Telecommunication_Engineering_Undergraduate_Program#Used_Equipment | Experimental Setup]].
| |
| We will use the [https://www.arduino.cc/en/Main/ArduinoBoardUno Arduino Uno] board as hardware platform, and will be developing software in C/C++ using the GNU compiler with the avrlibc.
| |
| We have plenty of Arduinos for use in the classroom, but if you can afford, you are encouraged to buy one for yourself to work on the extra-class assignments. They are available for less than R$50. [http://lista.mercadolivre.com.br/arduino-uno-r3 check MercadoLivre].

|
| |
| Arduino's microcontroller is Atmel's ATMega328P. Download its manual [http://www.atmel.com/images/atmel-8271-8-bit-avr-microcontroller-atmega48a-48pa-88a-88pa-168a-168pa-328-328p_datasheet_complete.pdf here].

| {{collapse top| bg=lightyellow | expandir=true | Homework 01: UART and Input/Output Buffers}}
| |
| For this homework, each student must:
| |
| #Execute [[ESTE: UART - Interrupts and Circular Buffer | Lab 05: UART - Interrupts and Circular Buffer]].
| |
| #Implement an UART Loopback Application with the following characteristics:
| |
| ##Use the Round-Robin With Interrupts architecture (suggestion: model it using a state-machine);
| |
| ##Use separate input and output buffers with configurable length;
| |
| ##Modify the application loop to use a delay to simulate data processing for each received byte (see loop pseudo-code bellow);
| |
| #Considering the application as a queue system, where bytes arrive through the serial and leave through the output buffer, analyze this communication problem using the queueing theory utilization theorem:
| |
| ##Define the worst-case arrival rate (A, in bytes/second, remember that an 8N1 serial will send 1 start bit, 8 data bits, and 1 stop bit);
| |
| ##Define the worst-case departure rate (D, in bytes/second, assume it is, in theory, the inverse of the processing time);
| |
| ##Compute the utilization of the queue (U=A/D, meaning that U is the amount of bytes going to the queue every second);
| |
| ##Build a graph where the x axis is the processing time (P={1,4,8}, ms) and the y axis is the minimum buffer size for a 1-second data transfer busrt;
| |
| ##Plot in this graph curves for different UART bitrates (B={19200,57600,115200}, bps).
| |
| #Finally, run the nine configurations of the experiment (PxB) in your board.
| |
| ##Compare the experimental results to the analytical model;
| |
| ##Plot the same graph for the experimental results;
| |
| ##Discuss and justify the differences and/or similarities of the analytical and experimental results.
| |
|
| |
| *Use [http://docente.ifsc.edu.br/arliones.hoeller/ste/milli_counter.tgz this timer implementation] to build the processing delay;
| |
|
| |
| Pseudo-code for the test application:
| |
| <syntaxhighlight lang=c>
| |
| void loop() {
| |
| char x = read_from_input_buffer();
| |
| delay(TIME);
| |
| write_to_output_buffer(x);
| |
| }
| |
| </syntaxhighlight>
| |
|
| |
| Students must hand-in the source code used in the experiment and a short report (2 pages max.) consisting of:
| |
| #Introduction (describe the problem being studied)
| |
| #Analytical model (equations and graph)
| |
| #Experimental Setup (Material and Methods)
| |
| #Results (the other graph)
| |
| #Discussion
| |
|

| |
| ##Use the Round-Robin With Interrupts architecture (suggestion: model it using a state-machine);
| |
