Here in the burner circuit an open collector output is provided to the reset pin and it is driven by the programmer through the port. Whatever, a push button is used in most cases to provide reset facility. Designers can provide a resistance capacitance reset circuit, but itвЂ™s not always necessary. Internal pull up resistors are provided at the reset pins and if nothing is connected to this pin, the micro controller tries to execute the program written within it. A low signal (Ground) drives it into programming mode. And computer internal circuits may also receive harms.ДЄ high signal (+5V) in the вЂ ResetвЂ™ pin of micro controller brings it into operational state. A resistance is necessary to limit the current in the nodes of Zener diodes, without the which the Zener diode may burn off. It is wired in such a way that it converts в‘2 volt signal to +5-0 volt signal which is suitable for the micro controller. In the programmer, Zener diodes provide necessary conditioning for the signals. Those signals from PC should be made suitable for micro controller. The signals transmitted from PC is not in a form that could be accepted directly by the micro controller. Micro controller always accepts 0 V as logic 0 and +5 V as logic one.

In this state, microcontroller is programmable in either mode (Parallel programming or serial programming). To enable programming, the microcontroller must be taken to the RESET state by pulling its reset pin LOW (Logic 0, or say 0 V). The micro controller, ATmega32 is programmed using the pins meant for SPI communication. It has a signal amplitude of +5 to +12 volt representing binary вЂ1вЂ™ and -5 to -12 representing вЂ0вЂ™. It uses PC COM PORT to download the program into the micro controller. My circuit is adapted from the website of Pony Programmer.

Now the software which I am talking about is named PONY PROGRAMMER 2.06. To burn a micro controller just the burning Hardware is not enough, it requires software also that would download the program present in a computer or memory device into the micro controller.

Here ISP stands for In System Programmer.

IвЂ™ve yet not written anything about programming.ДЄTmega32 series micro controllers support 3 types of programming So far IвЂ™ve discussed about the micro controller basics and the compiler software.
