The AVR chips all have internal hardware that can be used. For this description of the hardware the 90S8515 was used. Newer chips like the Mega8515 may differ and have more or less internal hardware. You will need to read the manufacturers data sheet for the processor you are using to learn about the special internal hardware available. Timer / Counters The AT90S8515 provides two general purpose Timer/Counters – one 8-bit T/C and one 16-bit T/C. The Timer/Counters have individual pre-scaling selection from the same 10-bit pre-scaling timer. Both Timer/Counters can either be used as a timer with an internal clock time base or as a counter with an external pin connection which triggers the counting. timer-counter prescaler

USB ASP Downloader for ATMega For programming the AVR microcontrollers, Atmel has provided special software that can be downloaded from the Atmel website. Software is AVRStudio. This software uses assembly language as the language of instrumentality. AVRStudio addition, there are some third party software that can be used to create programs on the AVR. These third-party software using high level programming language like C, Java, or Basic. To make removal from the computer into a chip, can be used several ways such as using JTAG cable or using artificial Atmel STK. However, you also can use the schematic circuit above to make a downloader ATMega microcontrollers based USB ports. Here is my USB downloader which I successfully created. Imade the USB ASP Downloader based ATMega8. hopefully can help you. Schematic circuit of USB ASP Downloader
