Hello Microphone Board
Programming Hello Microphone with the FabISP
Download the Files:
To program your Hello Microphone - download all the files - you need the c and makefile. Look at the back of the microphone - the negitive end is has marks that extend to the back of the case.
If Using ATtiny85 Instead
Note: If you are using a microcontroller with the same pin configuration but different memory (for example the ATtiny85 instead of the ATtiny45- you will need to edit the makefile.
To edit the makefile for the ATtiny85, open terminal and move to the directory where you downloaded the c code and makefile.
Type:
nano hello.mic.45.make
The program will open in the nano text editor (it looks like the code below)
Change each line with a "45" to "85". Except the line that says PROJECT=hello.mic.45. Leave that line.
PROJECT=hello.mic.45
SOURCES=$(PROJECT).c
MMCU=attiny85
F_CPU = 8000000
CFLAGS=-mmcu=$(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: $(PROJECT).hex
avrdude -p t85 -c bsd -U flash:w:$(PROJECT).c.hex
program-dasa: $(PROJECT).hex
avrdude -p t85 -P /dev/ttyUSB0 -c dasa -U flash:w:$(PROJECT).c.hex
program-avrisp2: $(PROJECT).hex
avrdude -p t85 -P usb -c avrisp2 -U flash:w:$(PROJECT).c.hex
program-usbtiny: $(PROJECT).hex
avrdude -p t85 -P usb -c usbtiny -U flash:w:$(PROJECT).c.hex
program-dragon: $(PROJECT).hex
avrdude -p t85 -P usb -c dragon_isp -U flash:w:$(PROJECT).c.hex
To save the file:
- press [control]+O to save the file
- press [control]+X to exit the editor
To Flash the Microntroller:
sudo make -f hello.mic.45.make program-usbtiny
If Working - This is the Terminal Output Produced (for ATtiny45)
avr-objcopy -j .text -O ihex hello.mic.45.out hello.mic.45.c.hex;\
avr-size --mcu=attiny45 --format=avr hello.mic.45.out

Run The Python Program (Ubuntu)
python hello.mic.45.py /dev/ttyUSB0
Run The Python Program (Mac)
Your serial port may be different depending on your computer. You need to find the port for your comupter. To find your serial port, with the board attached:, in terminal - type
ls /dev/tty.usb*
Then use the port you are given to run the python program. For example - when I type "ls /dev/tty.usb*", I get "/dev/tty.usbserial-FTF53NJC". So I would type:
hello.mic.45.py /dev/tty.usbserial-FTF53NJC

Hello Phototransistor
The purpose of this board is to take input from a phototransistor and display it visually using a python program when the board is connected to a computer via a FTDI cable. Link to the Fab Academy board diagrams / pngs and code. You need the c and the makefile.
Note: The collector side of the phototransistor is usualy marked in some way. Check the datasheet for the part you are using.
If Using ATtiny85 Instead
Note: If you are using a microcontroller with the same pin configuration but different memory (for example the ATtiny85 instead of the ATtiny45- you will need to edit the makefile.
To edit the makefile for the ATtiny85, open terminal and move to the directory where you downloaded the c code and makefile.
Type:
nano hello.light.45.make
