PICkit will execute these translated commands into MOSI/MISO/CLK pulses necessary to program our Atmel microcontroller. From here, the PICkit commands will travel through a real USB port, and the commands will arrive to PICkit 2. PK2AVRISP will translate the STK500 ISP commands into PICkit commands. We will trick the STK500 software to send the ISP commands to our virtual COM3 port instead of the real COM1 port.įrom the virtual port COM3, the ISP commands will travel through a virtual cable inside of the com0com software, and will arrive to virtual COM4.Īt the virtual COM4 we will connect another software, PK2AVRISP, which is in fact an ISP commands translator. In order to use a PICkit instead of a STK500 board, we will hijack the ISP commands. Based on the received ISP commands, the STK500 board will produce the MISO/MOSI/CLK pulses required to program the Atmel microcontroller. The STK500 software will produce ISP commands for the STK500 board, and will transmit those commands through physical serial port COM1, to the STK500 board.
In a normal data flow, when we have the physical STK500 programmer board, the microcontroller code (firmware) produced by the compiler is sent to STK500 software.
