Week 13 - Output Devices

The task

Add an output device to a micro-controller board and program it to do something.

The execution

I decided to make the hello LCD board

Milled and soldered board

The set-up

The pin numbering of the LCD is written on the rear so set-up is very straightforward

Modifications to the C file!

After initially recieving an error I found two changes that need to be made to program the board (on osx 10.7.5 at least)

LINE 225 and LINE 235 need 'const ' added to their start. They should now look like -

Programming

I was introduced to a nice free application this week that allows you to open a terminal window already directed to a file location. It's called Go2Shell

Flashing the bootloader required the following command line:

make -f hello.lcd.44.make program-avrisp2

Your LCD will now flash with the text "hello world"

You can alter this text in the C file, lines 225 & 235 between the quotations.
>>Save the Modified file and repeat .make command
