USBasp is a USB in-circuit programmer for Atmel
AVR controllers. It simply consists of an ATMega88 or an ATMega8 and a couple
of passive components. The programmer uses a firmware-only USB driver, no
special USB controller is needed.
Ø Materials
§ ATmega8 is an 8-bit AVR microcontroller that is based on RISC architecture
and is mainly used in the embedded system and industrial automation projects.
... The Program memory is 8K Flash, enough to store a number of instructions
while other two memories RAM and EEPROM contain 1K and 512 Bytes respectively.

Discussion
During I do it there are
many problems
·
Choosing components in Protuse is wrong
·
Making and
connecting components in schematic is wrong
·
And using circuit wrong
Conclusion
In
conclusion after I finished these project I could know about designing circuit
of schematic and PCB in Protuse. In addition I knew a lot of problems of it and
I can find of solution to make it well. Especially, I can know how to use of
it.
