7. Programming a Boot-loader
ATTENTION!
The described road-map in this chapter requires
programming experience!
You will be able to upload an Arduino-bootloader into the micro-
controller: for instance with the help of STK500.
In order to transfer any program, which has been written in Arduino
language, into the Atmega micro-controller the Atmega-processor
will have to be equipped with a special Arduino-boot-loader. This
boot-loader will be needed to take care of the correct location for
the coded characters inside the Atmega’s memory.
In order to install the boot-loader we will need the following compo-
nents:
* an AVR Programming Board (for instance the STK500 Board)
* a 12 Volt power supply
* the AAR-Robot including an on-board ISP-connector (fig. 7)
* a PC provided with a physical COM-Port (preferably NOT a USB-
RS232 converter, which might result in risks by timing-errors)
Please install (respectively update) the current version of the
Arduino-software, which will be found at the website www.arduino.
cc. The downloaded file probably will be delivered as a .ZIP- or
.RAR-type. Unpack these files and store the contents at your hard
disc.
Please apply e.g. WINAVR to transfer the Arduino boot-loader to
the robot.
Attention!
The ARDUINO software belongs to the freeware category and from
time to time it may happen that Arduino software and Arduino
boot-loaders do not properly cooperate!
If you experience such or similar problems you are invited to visit
the various Arduino websites respectively forums
