Hi! Welcome to Week 9
This week's assignment was to read a microcontroller data sheet
and program my board to do something.
This week's assignment was to read a microcontroller data sheet
and program my board to do something.
I have to admit it, I have never been this confused with an assignment before. At one point, I was completely lost, but then I decided to set the steps I'm going to take in order to finish the assignment on time. First I was going to prepare the MakeFile in accordance to the data sheet of the ATtiny44, then the c code, and then link the FabISP to the echo hello board and program it on Linux Mint.
A data sheet is a very, very, very long manual of the microprocessor, it is very hard for on to read it entirely, and so I just searched whatever I needed in it. here you can check the data sheet I used with the ATtiny44 I used previously. I used this data sheet to know what to change with the fuses on Neil's original Make file. This is how Neil's looked:
PROJECT=hello.ftdi.44.echo
SOURCES=$(PROJECT).c
MMCU=attiny44
F_CPU = 20000000
CFLAGS=-mmcu=$(MMCU) -Wall -Os -DF_CPU=$(F_CPU)
$(PROJECT).hex: $(PROJECT).out
avr-objcopy -O ihex $(PROJECT).out $(PROJECT).c.hex;\
avr-size --mcu=$(MMCU) --format=avr $(PROJECT).out
$(PROJECT).out: $(SOURCES)
avr-gcc $(CFLAGS) -I./ -o $(PROJECT).out $(SOURCES)
program-bsd: $(PROJECT).hex
avrdude -p t44 -c bsd -U flash:w:$(PROJECT).c.hex
program-dasa: $(PROJECT).hex
avrdude -p t44 -P /dev/ttyUSB0 -c dasa -U flash:w:$(PROJECT).c.hex
program-avrisp2: $(PROJECT).hex
avrdude -p t44 -P usb -c avrisp2 -U flash:w:$(PROJECT).c.hex
program-avrisp2-fuses: $(PROJECT).hex
avrdude -p t44 -P usb -c avrisp2 -U lfuse:w:0x5E:m
program-usbtiny: $(PROJECT).hex
avrdude -p t44 -P usb -c usbtiny -U flash:w:$(PROJECT).c.hex
program-usbtiny-fuses: $(PROJECT).hex
avrdude -p t44 -P usb -c usbtiny -U lfuse:w:0x5E:m
program-dragon: $(PROJECT).hex
avrdude -p t44 -P usb -c dragon_isp -U flash:w:$(PROJECT).c.hex
program-ice: $(PROJECT).hex
avrdude -p t44 -P usb -c atmelice_isp -U flash:w:$(PROJECT).c.hex
I changed the project definition, and from the data page, I found out that 0x5E should be changed in our board to 0x0A (but that didn't work out later) so this is the final makefile I used, I also removed the lines that I do not need.
PROJECT=cCode SOURCES=$(PROJECT).c MMCU=attiny44 F_CPU = 20000000 CFLAGS=-mmcu=$(MMCU) -Wall -Os -DF_CPU=$(F_CPU) $(PROJECT).hex: $(PROJECT).out avr-objcopy -O ihex $(PROJECT).out $(PROJECT).c.hex;\ avr-size --mcu=$(MMCU) --format=avr $(PROJECT).out $(PROJECT).out: $(SOURCES) avr-gcc $(CFLAGS) -I./ -o $(PROJECT).out $(SOURCES) program-usbtiny: $(PROJECT).hex avrdude -p t44 -P usb -c usbtiny -U flash:w:$(PROJECT).c.hex program-usbtiny-fuses: $(PROJECT).hex avrdude -p t44 -P usb -c usbtiny -U lfuse:w:0x5E:m
Next step was to create the C code for the board. I was previously familiar with the c++ language and I found that to be helpful this week. Also, our instructor Nadine walked us through the basics of programing using c and assembly. I planned to code my program using both, but I didn't have enough time to do it, as well as that I found assembly confusing and super tricky.
So for the C code, this is my code, with the explanation of why I used each line:
#include <avr/io.h> // Library for Linux
#include <util/delay.h> // the Library that contains the delay function
#define F_CPU20000UL // define the speed from the crystal on the board
#define LED PORTA // define the LED light
#define BUTTON PA7 // define the Button
int main (void){
DDRA = 0b00000100; //set PORTA 7 for input and 2 for output
while (1){
if(BUTTON==1){ //if the button is pushed
LED = 0b00000100; //set PORTA 2 high/on
_delay_ms(1000); // wait for 1 sec
LED = 0b00000000; //set PORTA 2 low/off
_delay_ms(1000); // wait for 1 sec
}
}
}
This part was fairly simple. After I finished it, I realized that this week wasn't as complicated as I thought. I proceeded by linking the FabISP with the Echo Hello board by linking all of the 6 pin heads on the ISP with its correspondent pin on the board.
In this part, I followed Nadine's steps in order to program my board. I added the following commands first:
sudo apt-get install flex byacc bison gcc libusb-dev avrdude
sudo apt-get install gcc-avr
sudo apt-get install avr-libc
sudo apt-get install libc6-dev
, then created a desktop file that had the make file saved from the text editor with no extension, and a code file with a .c extension.
I then started programming the board, and although I had trouble in the beginning with it as I kept getting an error whenever I gave the make command, it finally worked after editing the 0x0A (that was supposed to work from the data sheet) to 0x5E (the internal clock) in the code, starting the process again, and checking (and Fixing) the soldering between the board and some pin heads. and this is my log:
