SPARK V ATMEGA16 Hardware Manual
3.20 ATMEGA16 microcontroller
Spark V robot has ATMEGA16 microcontroller running at 7.3728MHz. .hex file is loaded using
boot loader software from NEX Robotics. In the bootloading process Reset and Boot switches
are used together. To know more about the boot loader, refer to section 4.6. Robot can also be
programmed by ISP (In System Programming) using AVR USB programmer from NEX
Robotics or ATMEL's AVR ISP mkII. It is recommended that you use boot loader software
instead of ISP. If ISP is used then is a chance that boot loader will get erased.
You can also use SPI pins of the microcontrollers as general purpose I/Os or as SPI port for
interfacing with external device. SS (Slave select) pin of the SPI port is available as pad. Refer to
figure 3.44 and 3.45 for SPI pins location.
You can access all the pins of the microcontroller by soldering on the pads which are located just
beside the microcontroller pin.
