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